NB: the easiest is to have global storage of tracer names/indexes in tracer.h => changed initracer.F & tracer.h to have global igcm_something indexes == 03/10/08 == - adaptations for surface ice index, modified files: phyetat0.F : if there is a dynamical tracer 'h2o_vap' then load surface tracer called 'h2o_ice' instead initracer.F : in 'old' tracer name case: move qsurf(nqmx)->qsurf(nqmx-1) and set i_h2o_ice=i_h2o_vap if iceparty=.false. physdem1.F : if old tracer names: move qsurf(nqmx-1)->qsurf(nqmx) if iceparty=.false., write surface tracer 'h2o_ice' (and not 'h2o_vap') to file. adapted vdifc.F, callsedim.F & watercloud.F & physiq.F so that surface ice is now identified as qsurf(i_h2o_ice) - updated aeronomars/perosat.F (cosmetics) == 06/10/08 == - modify newstart.F and lect_start_archive.F to use tracers by name == 07/10/08 == - adapted inichim_newstart.F (added qsurf to arguments) and inichim_readcallphys.F == 08/10/08 == - implement reading traceur.def in dyn3d/iniadvtrac.F == 16/10/08== -small change in inifis.F (only warn if too many tracers, compared to the expected number, not stop). - corrected bug in initracer.F == 21/10/08 == - modified newstart.F to load B.Diez subsurface ice maps. - corrected small bug (uninitialized variable) in interp_horiz.F == 22/10/08 == - updated iniwritediagsoil.F so that thermal inertia is written to diagsoil.nc == 31/10/08 == - changed xvik.F program so it works even if we don't have atmospheric temperature at hand (then it uses a 10km reference scale height) and so that it does surface pressure interpolation log-wise. == 03/11/08 == - modified physiq to compute (and output) co2 column. - added improvement by Francois in newcondens.F about computing CO2 partial pressure.

Central function is callcorrk.F. Radiative properties are no longer stored in dimradmars.h, but in the two files radinc_h.F90 and radcommon_h.F90. 3D aerosol scheme incorporated into callcorrk.F. dustopacity.F renamed aeropacity.F and substantially simplified. For now the option to include dust as an aerosol has been removed. >>> newcondense.F replaced by condense_co2cloud.F90. This is basically Francois' routine from the old model, adapted to work with the new generalised tracer scheme. >>> Options added in physiq.F and tabfi.F to allow for planets with varying orbital parameters, radii, gravity etc. For the moment we select the planet using the variable 'planettype' in callphys.def. This could probably be improved in the future. >>> Many new options added to callphys.def. == 25/11/2009 == >>>> List of changes and modifications - modified watercloud.F: added sanity check (i.e. do we have a water tracer?) - modified dyn3d/dynetat0.F --> removed possibility of reindexing tracers - modified phyetat0.F --> removed possibility of reindexing tracers -- removed using a "co2ice" array to store surface CO2 ice -> adapted surfini.F & physiq.F to use qsurf(:,igcm_co2_ice) instead of co2ice(:) -> modified initracer.F & tracer.h to properly initialize (and store) a "co2_ice" tracer. -> removed 'co2ice' from vdifc.F (it was not used there anyway) and from phsdem1.F -> removed possibility of calling 'newcondens' from physiq.F -> cleaned up newstart.F, lect_start_archive.F, start2archive.F to not use "co2ice" field but qsurf(igcm_co2_ice) -- adapted 'create_make_gcm' and 'makegcm' scripts so that we don't need to have and (unused) 'aeronomars' directory around. -- shifted to reading traceur.def (dyn3d/iniadvtrac.F) in an Earth-LMDZ4-like fashion: first line == number of tracers and then tracer name (1 per line; later we'll also add advection scheme type) -- NOTE BY RW: Here would be a good place to also note which tracer (if any) is the 'variable gas' in the radiative transfer -- Made some changes in tabfi.F to let user change planet parameters such as rotation rate, molar mass of atmosphere, ... (NB: note however that we seem to lose dynamics/physics coherence ... we should probably read these values from a planet.def file) -- Changed condens_co2cloud.F : added a check for presence of CO2 gas and output of corresponding tendency. == 15/12/2009 == >>> Correlated-k radiative transfer now reads spectral bands and p-T matrix values from ascii files; the code checks that the number of bands and matrix elements in the files match those written in radinc.F90 on the first call. >>> Water vapour tracer coupled to variable gas species in radiative transfer; option also given to run with fixed relative humidity profiles. 'Variable gas species' option added to callphys.def. >>> Surface albedo updated to be one band everywhere. >>> suaer_corrk.F90 modified to use different ep, omeg, g variables in the visible and infrared. This is necessary because the number of bands is, in general, different. >>> suaer_corrk.F90 has an option to accept Francois' new CO2 ice values (and convert wvl to metres!!). >>> optci.F --> optci.F90 so that water vapour continuum subroutine can be included. == 08/01/10 == >>> Option to change pref for hybrid coordinates added to newstart.F. == 15/01/2010 == >>> Upgraded newstart.F: added possibility to reset refrence surface pressure "preff" (and pa) >>> tabfi.F: added possibility of changing value of "year_day" >>> cosmetic change in callphys.def : separate "universal" parameters and planet-specific parameters (in a separate file, e.g. earlymars.def) == 22/01/2010 == ==> call this version LMDZ.GENERIC >>> Some cleanup & upgrades: -- split parameters in callphys.def into generic stuff (stays in callphys.def) and another more specific file (e.g. earlymars.def). -- added 'output_olr' key (in callkeys.h; read in physiq.F) to trigger output of fluxes in ascii file 'olr.txt' -- removed (non-generic) 'kastprof' and 'nearcond' keys/options in physiq.F (also removed file kastprof_fn.F) -- had to set 'fixh2ovap =.false. in callcorrk.F to avoid "out of range subscript" pb in callcorrk.F ==> this should be improved / better controlled in the future -- updated newsedim.F to use "molrad, visc, avogado values from comcstfi.h (and not local versions of these constants) -- fixed buggy -O option in makegcm (and makegcm_g95); == 22/02/2010 == ==> call this version LMDZ.GENERIC.v0.31 -- rain.F, manabe.F and largescale.F subroutines added to water cycle -- several new toggles added to earlymars.def == 28/03/2010 == ==> call this version LMDZ.GENERIC.v0.4 -- many changes for this version! -- radiative transfer -- A new system was implemented that automatically reads the p, T, g, Q and band values from files. The dataset required is now specified in callphys.def. We still need to edit radinc_h when the corrk array sizes change - think about improving this in the future. -- water cycle -- A watercommon_h mod file was created, several files were renamed and moist convection and precipitation subroutines were added. Still needs some testing! -- OLR -- Two new functions were added: one to produce .nc files of the OLR by band, and the other to save the upgoing radiation by band in 1D as a .txt file. -- general structure -- tabfi.F, newstart.F etc. cleaned up + it was checked that they pass variables correctly. Several new options added to run.def for 1D, in order to allow truly arbitrary planet simulations. The 'planettype' option has been removed as it screwed things up completely. -- energy conservation -- I found that the planckir function in the radiative transfer did not always produce values that summed to sigma T^4. A new test was implemented to check for this problem and the standard band widths in the IR were increased. == 31/03/2010 == ==> call this version LMDZ.GENERIC.v0.5 -- OLR -- The .nc functions were implemented and tested. It was necessary to add new functions 'writediagspec.F' and 'iniwrite_spec.F'. -- CO2 condensation -- In 1D we now exit automatically if CO2 is condensing on the surface. -- G1D -- We can now choose at the beginning of physiq.F, using saveG1D, how many times we want to save per day in 1D (rather than every single time that physiq is called). -- water cycle -- I corrected a nasty bug in callcorrk involving varfixed, real*8 and epsi. I corrected a simple bug in the writing of qsurf in g1d.dat. rain.F has been tested and the algorithm for precipitation evaporation modified to that written in the manual of Larent Li. Cloud fraction variable is now included. activice and iceparty are gone, ~replaced by watercond and waterrain. -- orbit -- nres and tlocked were added as basic options to callphys.def -- radiative transfer -- I added error checking for out-of-bounds temperature in callcorrk.F. I added a new file calc_rayleigh.F90 to calculate Rayleigh scattering using a weighted mean, as opposed to simply the midpoint band values. Band discretisation is now even more automated than before: the coefficients are stored in directories like /earth/32x36/, and we can compile the GCM like this: makegcm -d 32x24x20 -b 32x36 -p std gcm. A bug was fixed involving emissivity not being properly passed from newstart.e to the main part of the code. Stellar spectra are now calculated automatically for any range of bands from high resolution data (originally from the VPL website). -- vertical discretisation -- I corrected a bug in testphys1d that used a fixed value of temperature to compute the altitude levels in the model. Now we use the scale height from z2sig.def instead. Values of preff and pa are no longer defined in testphys1d (they're not needed). -- Non-ideal gases -- I have replaced cpp in many places with cpp_3D in physiq. This is a major change, but there are enough cases where it will be useful to make it worthwhile in the universal code. I have done the same with rcp. == 10/10/2010 == ==> call this version LMDZ.GENERIC.v0.6 -- startup -- We now check water tracers exist in newstart.F before all watery initialisation options. Added an option 'autozlevs' to run.def (and logic.h). When true this recalculates the scale height in z2sig.def in order to get the same minimum pressure for any resolution. Currently, this is only useful for one-d simulations. Pressure is now distributed better in newstart.F. There was a bug before when the global mean of phi was not equal to zero and the surface pressure was changed with topography still present. In initracer, we no longer automatically set h2o_vap=h2o_ice. -- general -- periheli, apheli --> periastr, apoastr. Note this necessitates a change in start_planet too. testphys1d.F --> rcm1d.F physiq.F, callcorrk.F upgraded to Fortran 90 to remove evil zerophys. I cleaned up the method of displaying energy balance and temperature range in the model a bit. Pure H2 atmospheres are now permitted, although the code is _untested_. Rayleigh scattering, specific heat capacities and molar masses are varied, and the H2-H2 collision-induced data of Grushka et al. is used for the radiative transfer. -- boundary layer -- An improved version of vdifc.F has been created that includes the latent heat effect of water vapor, following the method used in 'clmain' in the LMDZ terrestrial model. -- water cycle -- Benjamin's improvements have been added, namely the hydrology, and reevaporation. Variable cloud fractions are allowed, or a global fixed value may be chosen for use in aeropacity. Surface wetness (beta) is now calculated in a simple way, and outputed as a diagnostic, along with the atmospheric relative humidity. mol/mol to kg/kg bug in callcorrk corrected. -- radiative transfer -- A major bug in gfluxv.F was corrected. It involved BSURF, the radiation reflected upwards from the ground. In aeropacity, we now set the cloud opacity in the top layer of the atmosphere to zero. This solves an instability problem that was occurring when CO2 clouds formed. Dust is back! Only fixed profiles allowed for now. It is assigned "naerkind=3" in aeropacity.F90. If 'CLFvarying' is enabled, the corrk subroutine is now called twice per timestep - once for clear skies and once for cloudy. This slows things down but is effective for Earth-like simulations. An optional Newtonian cooling scheme has been implemented that can replace the correlated-k method for dynamical tests etc. It is pretty experimental and has not been extensively tested. -- Dynamics -- callgroupeun in gcm.F has been set to FALSE, as it does not conserve tracers. The coefficient facup has been set to 1 in inidissip.F. We may need to mess with this later if it makes the model too unstable. == 1/08/2011 == ==> call this version LMDZ.GENERIC.v0.7 Main change: a new file 'gases.def' now required at startup. This tells us which gases are in the planet's atmosphere. It is used to calculate fundamental quantities like cpp and mugaz. A check is made against the radiative transfer data to make sure they correspond. Code has been tested successfully using the 'gfortran compiler'. -- startup -- a bug involving tsoil interpolation in lect_start_archive.F was corrected. -- aerosols -- gauss integration number 5-->10 in aeroptproperties.F90 -- water cycle -- Big fat bug in rain.F90 corrected. The routine internally updated the temperature with new tendencies before it was supposed to happen! Bug in oborealis where phi not properly updated was corrected. Improvements to hydrol.F90: zdtsurf_hyd --> pdtsurf_hyd A 'sourceevol' option was added (accessed in callphys.def) that allows us to track the evolution of the surface distribution over time. Another bug in rain corrected involving evaporation - it was heating the atmosphere rather than cooling it... -- convection -- I found a bug in convadj.F that breaks tracer conservation when convection stops at one layer and immediately restarts in the next one. -- diagnostics -- Some bugs corrected in the computation of 3D averages for the H2O / energy conservation diagnostics. -- radiative transfer -- A bug involving continuum opacities (variable DCONT) was corrected in optci.F90 and optcv.F0. H2-H2 warming now in theory reliable and correct (60-1000 K). A bug involving the definition of the Planck function boundaries was corrected in sfluxi.F90 and gfluxi.F. == 21/10/2011 == EM - added FF's upgrade of writediagfi. Now, if at runtime there is a diagfi.def file, it should contain the list of variables (1 per line) than will be put in the diagfi.nc file. If there is no diagfi.def file, then all variables are put in the diagfi.nc file (as was the case before). === 10/11/2011 == EM - Updated the makegcm(s) so that default behaviour is to set LMDGCM env variable to be the directory in which the makegcm script is. Updated the makegcm_* to use "SOURCE" to identify code and be compatible with latest 'create_make_gcm'. == 10/11/2011 == EM - Upgrade: The location of the 'datagcm' directory can now be given in the callphys.def file ( datadir = /absolute/path/to/datagcm ). Changed "datafile.h" into a F90 module "datafile_mod.F90" and spread this change to all routines that used to use "datafile.h". == 10/11/2011 == EM - Upgrade of the 'create_make_gcm' script: objects are removed from the libraries before compilation, which enforces that the gcm will fail to compile if any routine failed to compile. == 12/12/2011 == AS - Use of allocatable arrays to set corrk stuff through reading *.dat files, without the need to change radinc_h manually. - Allocation is done in sugas_corrk which is within firstcall loop in callcorrk. - Note that N_LGAUSS is still a parameter. It is not supposed to change much. - Compiles fine. Tested with debugging options through pgdbg. Runs fine. Exact same results in Early Mars test case. Modified files: M 469 libf/phystd/physiq.F90 M 469 libf/phystd/sugas_corrk.F90 M 469 libf/phystd/callcorrk.F90 M 469 libf/phystd/radinc_h.F90 M 469 libf/phystd/radcommon_h.F90 == 13/12/2011 == AS - Same spirit as previous commit, but for ngasmx which is now read in gases.def -- before arrays w/ dim ngasmx are allocated dynamically - Allocation is done in su_gases.F90 which is called in inifis - Outside su_gases.F90, very few modifications to the code : the new module "gases_h.F90" simply replaces the old common "gases.h" ! - Compiles fine. Tested with debugging options through pgdbg. Runs fine. Exact same results in Early Mars test case. == 20/12/2011 == JL + AS - Allocatable gastype in sugas_corrk instead of hardcoded (it was a problem for more than 4 gases!) == 13/02/2012 == JL + AS - All outputs are now in netCDF format. Even in 1D (No more G1D) - Clean up of the call to callcorrk when CLFvarying=true - Corrects a bug in writediagspecIR/VI. Output are now in W/m2/cm-1 as a function of the wavenumber in cm-1 - Enable writediagspecIR/V to work in the CLFvarying=true case (output now done in Physiq after writediagfi) - Add a simple treatment for the supersaturation of CO2 (see forget et al 2012) - corrects a small bug when no clouds are present in aeropacity == 16/02/2012 == JL + EM - Mesh area now present in 1d diag files. - Spectral Bandwidth included in the diagspec files - Correction of a initialzation bug on day_step and ecritphy in rcm1d == 17/02/2012 == RW - qsurf bug in variable species rad. tran. removed - line to update kappa in newstart.F added - necessary to synchronise dynamics and physics - three obsolete files removed from dyn3d/ directory - calc_cpp_mugaz --> check_cpp_mugaz, with override option in callphys.def - kcm1d no longer consistent with new code, but I haven't updated as I'm still working on it and as far as I know noone else uses it. If that changes let me know. == 27/02/2012 == AS - Temperature grid for Planck calculations can now be refined through the parameter NTfac in radinc_h. Default is NTfac = 1.0D-1, i.e. Delta T = 0.1 K == 16/03/2012 == JL - Removed cpp3D and nonideal stuff. == 19/03/2012 == EM Some cleanup and bug fixing: - "cloudfrac" was not well written to restartfi (wrong size). - missing save attribute for "reffrad" in physiq.F90. - cleanup recomputation of surface pressure in newstart and change loop order in interp_horiz (which "fixes" an odd behaviour which fills some arrays with zeros, but only when using some versions of ifort!) == 19/03/2012 == AS - Cleaned rcm1d.F and made it truly generic by asking for planetary constants without any default values. - Settings are now needed in a rcm1d.def file. Unbeknown to the user, we create a minimal run.def file, read parameters, then remove this dummy run.def. - Introduced a keyword force_cpp if the user wants to give values for cpp and mugaz in def files. == 19/03/2012 == AS+FF - Introduced global1d in callcorrk so that global (using sza) or local (using latitude) 1D simulations can be carried out. - Converted all astronomical distances in AU instead of Mkm. - This might cause problems with old start files. So added a test in iniorbit. A quite dirty test, but that'll do the job. == 22/03/2012 == JL - New turbulent diffusion scheme solving "most" energy conservation problems: - Turbulent energy created by buoyancy effects is now dissipated back into enthalpy - the scheme is now written in an enthalpy conservative way - Turbulent diffusion now treated in routine turbdiff (in F90). - Temporarily, for comparison, the old vdifc can be used by setting UseTurbDiff=.false. in physiq.F90 - The sensible heat flux is now an output - Corrected evaporation at the surface when all the surface water is evaporated (JL+BC). - Added new energy conservation diagnostic variables and output == 26/03/2012 == JL - Added double gray case (if graybody=true in callphys.def): - opacities are set to a constant value in sugas_corrk. - the values are kappa_IR m^2/kg in the infrared (to be read in callphys.def) kappa_VI m^2/kg in the visible (to be read in callphys.def) - Cleaned continuum part in optc* - Added .def files for a typical 1d earth case in deftank (dry case for the moment) - Corrects a bug on potential temperature calculation in physic == 27/03/2012 == JL - Corrects the computation of planck function at the surface in sfluxi so that its integral is equal to sigma Tsurf^4. - This ensure that no flux is lost due to: -truncation of the planck function at high/low wavenumber -numerical error during first spectral computation of the planck function -discrepancy between Tsurf and NTS/NTfac in sfluxi - OLR now equal to LW net heating/cooling at equilibrium! - As much as possible, only the value of the stephan boltzmann constant defined in racommon_h (and the corresponding variable, sigma) should be used. Now done in physics, vdifc and turbdiff. == 16/04/2012 == JL - Added consistency checks for calculations including water and global1d+diurnal. - Corrected small bugs in precipitation scheme == 04/05/2012 == JL - Correction a huge bug in newstart: rcp and cpp can now be changed in start.nc files and are the same as in startfi.nc; Even when starting from start and startfi files. - rcp, cpp and mugaz can now be computed using gases.def in newstart - Correction of a bug arising in gcm.F when the solar days are long (thanks Melanie V.) - Corrected the temperature used to differentiate sublimation and evaporation in watersat_grad - Minor name changes in watercommon - Better physical parametrization of the effective radius of liquid and icy water cloud particles in callcorrk (for radfixed=true) - Added consistency check in inifis - Moved 1d water initialization from physiqu to rcm1d - All enertests in physiq written in a matricial (F90) way. The rest of physiqu should follow soon == 25/05/2012 == EM - Significant update on how the number of scatterers is managed: Instead of having to manualy change 'nearkind' in radinc_h.F90, the number of scatterers must now be set when compiling, using makegcm "makegcm -s 1" for one scatterer or "makegcm -s 2" for two (e.g. dust and water ice), default behaviour (ie not specifying -s #) is -s 1 Modified phystd/radinc_h.F90 , added directory phystd/scatterers with script make_scatterers , and adapted makegcm* scripts. == 06/06/2012 == EM - Corrected the polar mesh surface area which was wrong in the physics (changes in phyetat0.F, calfis.F and newstart.F) - Some cleanup in newstart.F (removed some obsolete "Mars" options: mons_ice,..) and also added option "q=profile" to initialize a tracer with a profile read from file "profile_tracername" == 29/06/2012 == EM - Some cleanup in start2archive.F and ini_archive.F to get them to work for the generic model (removed some "Martian" specificities). == 17/07/2012 == JL for LK - Generalization of aerosol scheme: - any number of aerosols can be used and id numbers are determined consistently by the code. Aerosol order not important anymore. - addition of a module with the id numbers for aerosols (aerosol_mod.F90). - initialization of aerosols id numbers in iniaerosol.F90 - compile with -s x where x *must* be equal to the number of aerosols turned on in callphys.def (either by a flag or by dusttau>0 for dust). => may have to erase object files when compiling with s option for the first time. - For no aerosols, run with aeroco2=.true. and aerofixco2=.true (the default distribution for fixed co2 aerosols is 1.e-9; can be changed in aeropacity). - If starting from an old start file, recreate start file with the q=0 option in newstart.e. - update callphys.def with aeroXXX and aerofixXXX options (only XXX=co2,h2o supported for now). Dust is activated by setting dusttau>0. See the early mars case in deftank. - To add other aerosols, see Laura Kerber. == 18/07/2012 == JL - New water cycle scheme: - largescale now in F90. Robustness increased by i) including evap inside largescale ii) computing the condensed water amount iteratively - same improvements in moistadj. - Water thermodynamical data and saturation curves centralized in module watercommn_h - The saturation curves used are now Tetens formula as they are analyticaly inversible (Ts(P)-> Ps(T)). New saturation curve yields very good agreement with the former one. - Saturation curves are now generalized for arbitrary water amount (not just q<<1) - The old watersat should be removed soon. - The effect of water vapor on total (surface) pressure can be taken into account by setting mass_redistrib=.true. in callphys.def (routine mass_redistribution inspired from co2_condense in martian model but with a different scheme as many routines evaporate/condense water vapor). - New cloud and precipitation scheme (JL + BC): - The default recovery assumption for computing the total cloud fraction has been changed (total random gave too large cloud fractions). See totalcloudfrac.F90 for details and to change this. - Totalcloudfraction now set the total cloud fraction to the fraction of the optically thickest cloud and totalcloudfrac is thus called in aeropacity. - Only the total cloud fraction is used to compute optical depth in aeropacity (no more effective optical depth with exponential formula). - 4 precipitation schemes are now available (see rain.F90 for details). The choice can be made using precip_scheme in callphys.def. Usage of the more physically based model of Boucher et al 95 (precip_scheme=4) is recommended. default behavior is set to the former "simple scheme" (precip_scheme=1). - See rain.f90 to determine the parameter to be defined in callphys.def as a function of the precipitation scheme used. - Physiq.F90 now written in a matricial (more F90) way. - Radii (H2O and CO2 cloud particles, aerosols, duts, ...) calculations now centralized in module radii_mod.F90 and work with the new aerosol scheme implemented by Laura K. Some inconsistency may remain in callsedim. - Corrected gray gas mode. The use of kappa_VI or kappa_IR far a given band is now based on its wavenumber independently of SW and LW calculations Implementation compiled with ifort and pgf90. gcm.e runs in Earth and Early Mars case with CO2 and H2O cycle + dust. == 19/07/2012 == JL - Corrected precipitation evaporation scheme + snow fall (JL+BC) - Commented some unecessary writediagfi calls that where used for test. == 24/07/2012 == JL - Correction of a bug in turbulent diffusion (turbdiff.F90) => This solves a water conservation problem arising when the code tries to evaporate over dry land. == 26/07/2012 == AS - Bug fix in physiq : the size of OLR_nu is L_NSPECTI and not L_NSPECTV - A more robust aerosol_mod + iniaerosol : problems with ifort+parallel solved, while still OK with other compilers and seq runs. == 05/09/2012 == JL - Correction of the calculation of the solar longitude in tlocked case. -Can now handle any prograde resonance with nres=omega_rot/omega_orb. -Sun now goes westward for the standard 2:1 case, as expected. - In the gray case, the separation between kappa_IR and VI is now set by wave number, independently of the usual IR/VISIBLE calculation separation. i.e. kappa_IR can be used in the calculation of the downward stellar flux if the wavenumber in the band is low enough and vice versa. - In ave_stelspec, stellar flux averaging has been generalized to incorporate very red/blue stellar spectra (great care must however be taken of the band limit used for the corralated k distributions). -Brown dwarf spectra from Allard et al. have been added. -Any Black body temperature can now be used. == 19/09/2012 == JL - Correction in largescale to improve robustness when large water vapor amount - Correction in soil_setting to allow change of the number of subsurface layers == 19/09/2012 == AS (Sorry for long text but this is a quite major commit) Paving the path for parallel computations. And moving towards a more flexible code. Automatic allocation is used within all routines in phystd. No further mention to ngridmx and nqmx. 1. ngridmx and nqmx are still used in LMDZ.GENERIC in the dyn3d part 2. if the LMDZ4/LMDZ5 dynamical core is used, there is no more fixed dimensions ngridmx and nqmx --> a fully flexible parallel implementation is now possible (e.g. no need to recompile when changing numbers of processors) The important stuff : - Compilation checked with ifort. OK with and without debug mode. No errors. Checked for: gcm, newstart, rcm1d, kcm1d - RUN GCM: Running an Earth test case. Comparison with previous revision --> debug mode : perfect match. bit by bit (diff command). checked with plots --> O1 mode : close match (checked with plots) --> O2 mode : sometimes up to 0.5 K departure.... BUT in this new version O2 and O1 are quite close while in previous version O1 and O2 differed by about, well, typically 0.5 K (pictures available on request) - RUN NEWSTART : perfect match (bit-by-bit) in either debug or normal mode. - RUN RCM1D : perfect match in normal mode. - RUN KCM1D : not tested (I don't know what is the use of kcm1d) List of main changes : - Additional arguments to some subroutines (ngrid and nq) - F77 include strategy is obsolete and replaced by F90 module strategy In this new strategy arrays are allocatable and allocated once at first use This has to be done for all common featuring arrays defined with ngridmx or nqmx surfdat.h >> surfdat_h.F90 tracer.h >> tracer_h.F90 comsaison.h >> comsaison_h.F90 comgeomfi.h >> comgeomfi_h.F90 comsoil.h >> comsoil_h.F90 comdiurn.h >> comdiurn_h.F90 fisice.h >> DELETED. was not used. probably a fossil. watercap.h >> DELETED. variable put in surfdat_h.F90 - F77 'save' strategy is obsolete and replaced by F90 'allocatable save' strategy (see previous point and e.g. new version of physiq.F90) - Suppressing any mention to advtrac.h which is a common in the dynamics and needs nqmx This was easily solved by adding an argument with tracer names, coming from the dynamics This is probably not a definitive solution, ... but this allows for generic physics to work easily with either LMDZ.GENERIC or LMDZ dynamical cores - Removing consistency tests between nq and nqmx ; and ngrid and ngridmx. No use now! - Adaptation of rcm1d, kcm1d, newstart given above-mentioned changes A note on phyetat0 and soil_setting: - Now written so that a slice of horizontal size 'ngrid' starting at grid point 'cursor' is read in startfi.nc 'cursor' is defined in dimphys.h and initialized by inifis (or in newstart) this is useful for parallel computations. default behavior is the usual one : sequential runs, cursor is 1, size ngrid is the whole global domain A note on an additional change : - nueffrad is now an argument to callcorrk as is the case for reffrad both are saved in physiq this is for consistency and lisibility (previously nueffrad was saved in callcorrk) ... but there is a call to a function which modifies nueffrad in physiq ... previously this was not modifying nueffrad (although it was quite cumbersome to detect this) ... to be conservative I kept this behaviour and highlighted it with an array nueffrad_dummy ... I added a comment because someone might want to change this == 20/09/2012 == AS A more robust way to count lines in setspi and setspv. bandlen.txt file is no longer used. This was causing problems with MPI computations. == 06/11/2012 == EM - Fixed bug in disvert: pseudo-altitude pseudoalt() should be computed using the scale height H provided in "z2sig.def" (and not 10.0).
