Users should not use the thermals yet, as several major configuration changes still need to be done. This version includes : - updraft and downdraft parametrizations - velocity in the thermal, including drag - plume height analysis - closure equation - updraft transport of heat, tracers and momentum - downdraft transport of heat This model should not be used without upcoming developments, namely : - downdraft transport of tracers and momentum - updraft & downdraft transport of q2 (tke) - revision of vdif_kc to compute q2 for non-stratified cases Thermals could also include in a later revision : - momentum loss during transport (horizontal drag) Compilation of the thermals has been successfully tested on ifort, gfortran and pgf90 ================================================ ================================================ M libf/phymars/callkeys.h M libf/phymars/inifis.F Added new control flags to call the thermals : - calltherm (false by default) <- to call thermals - outptherm (false by default) <- to output thermal-related diagnostics (for dev purposes) ================================================ M libf/phymars/vdifc.F ^------> added a temporary output for thermal-related diagnostics M libf/phymars/testphys1d.F ^------> added treatment for a initialization from a profile of neutral gas (ar) -> will be transformed in a decaying tracer for thermal diagnostics M libf/phymars/physiq.F ^------> added a section to call the thermals -> changed the call to convadj -> added thermal-related outputs for diagnostics M libf/phymars/convadj.F ^------> takes now into account the height of thermals to execute convective adjustment => note : convective adjustment needs to be activated when using thermals, in case of a second instable layer above the thermals ================================================ A libf/phymars/calltherm_interface.F90 ^------> Interface between physiq.F and the thermals A libf/phymars/calltherm_mars.F90 ^------> Routine running the sub-timestep of the thermals A libf/phymars/thermcell_main_mars.F90 ^------> Main thermals routine specific to Martian physics A libf/phymars/thermcell_dqupdown.F90 ^------> Thermals subroutine computing transport of quantities by updrafts and downdrafts A libf/phymars/thermcell.F90 ^------> Module including parameters from the Earth to Mars importation. Will disappear in future dev ================================================ ================================================ == 17/06/2011 == EM >>> Updates and corrections (to enable compiling/running in debug mode with ifort) - removed option "-free-form" from makegcm_ifort and set mod_loc_dir="." so that module files (produced in local directory by ifort) are moved to LIBO - updated initracer.F, physdem1.F, physiq.F, inichim_newstart.F to avoid referencing out-of-bound array indexes (even if unused) - cosmetic updates on inwrite.F, datareadnc.F - updated newstart.F to initialize and use 'datadir' when looking for files - corrected bug on interpolation of sub-surface temperatures in lect_start_archive.F == 17/06/2011 == AC >>> Important updates to thermals parameters - Tuned aspect ratio of thermals to suit Buoyancy estimations from LES in CLOSURE relation - Renormalization of alim_star after plume - Removed alimentation mixing of estimated Teta in plume >>> Minor change in makegcm_ifort == 22/06/2011 == EM - added modifications (from JYC & FGG) to tracer.h & initracer.F for ions - minor improvement to newstart.F (q=x option, check that tracer index provided by user is valid). - minor correction to callradite.F (to enable compilation in debug mode with ifort when there is only one tracer). == 17/06/2011 == AC - Added maximum vertical velocity and heat flux output from thermals - Added buoyancy diagnostics - Minor modifications in thermals routines == 23/06/2011 == EM - correct bug (introduced previously) in lect_start_archive.F on loop boundaries for soil temperature. == 01/07/2011 == AC - Added new settings for the Martian thermals from new LES observations - Revamped thermcell's module variables to allow it's removal - Minor changes in physiq and meso_physiq for the call to thermals - Switched from dynamic to static memory allocation for all thermals variable to gain computation speed == 04/07/2011 == AC - Minor setting modification to thermals - Added new flux optimization in thermcell_main_mars.F90, to run properly in 3D == 14/07/2011 == JBM - Tidying up dust properties in DATAFILE for better consistency (cf. suaer.F90) - Cosmetic changes in aeropacity.F (changed comment and put a print inside a water flag) == 15/07/2011 == EM >> Implemented using 'z0' roughness length map (important: 'z0' reference field is in datafile surface.nc, which has also been updated). - made z0 a z0(ngridmx) array and moved 'z0' from 'planete.h' to 'surfdat.h'; added a 'z0_default' (common in surfdat.h) corresponding to the 'control' array value (contole(19) in startfi.nc). - adapted 'tabfi.F' to use 'z0_default'. - adapted 'phyetat0.F' to look for a 'z0' field in startfi.nc. If 'z0' is not found in the startfi.nc file, then the uniform default value (z0_default) is used. - modified 'physdem1.F' to write 'z0' field to restart.nc - adapted use of z0() in 'physiq.F' (diagnostic computation of surface stress), 'vdifc.F' and 'vdif_cd.F'. - adapted 'dustdevil.F' to use 'z0_default'. - 'testphys1d.F' now uses 'z0_default', and the value to use can be set in run.def (with "z0=TheValueYouWant"). - modified 'datareadnc.F' to load reference map of 'z0' from surface.nc, and added a 'z0' option in 'newstart.F' to force a uniform value of z0. Note that the use of the z0 map is automatic when using newstart, but only when it loads a start_archive.nc file. == 15/07/2011 == AS - Modified the mesoscale part so that the previous change by EM does not imply an error in the mesoscale case. More development is needed though to get the "varying z0" capability in the mesoscale model. - Worked on versions of meso_physiq and meso_inifis as close as possible to physiq and inifis for more continuity in the process of impacting changes (and even possibly to reach a common version of physiq and inifis). >>> The main point is to make the mesoscale significant specific parts coded into include files in meso_inc so that meso_physiq and meso_inifis looks very close to physiq and inifis. >>> This is completely transparent for GCM users who does not need the contents of meso_inc. - Slight cosmetic changes to physiq.f and inifis.F --- some of them e.g. to prepare convergence between meso_physiq and physiq - Dropped the meso_ prefix from the slope routines (currently those are only used in the mesoscale model, but one could imagine using those in hi-res GCM runs) - Added a MESOSCALE flag to writediagfi so that mesoscale simulations are not bothered with calls put in routines by GCM people == 19/07/2011 == AS - Finished converging meso_physiq.F and meso_inifis.F towards physiq.F and inifis.F --> see previous point 15/07/2011 --> meso_ routines no longer exist (everything is in meso_inc and transparent to GCM users) --> GCM routines include mesoscale parts within MESOSCALE precompiler commands --> MESOSCALE parts are as hidden as possible not to mess up with GCM users/developers - Cleaned inelegant or useless #ifdef [or] #ifndef MESOSCALE in physiq and inifis so that a minimum amount of such precompiler commands is now reached [mainly related to I/O] - Added the SF08 slope insolation model in the general physics parameterizations. Added a callslope keyword in inifis.F and callkeys.h --> This keyword is False by default / True if you use -DMESOSCALE - Removed the obsolete call to Viking Lander 1 diagnostic Replaced it with a diagnostic for opacity at the domain center [valid for GCM and mesoscale] == 01/08/2011 == EM - Fixed bug in readtesassim (timeflag was not always set before being used) == 03/08/2011 == AC - Modified physiq.F to interface new SL parametrization - New SL parametrization based on a bulk Richardson Monin-Obukhov theory formulation Stability functions are taken from D.E. England et al. (95) Similarity functions coefficients based on Dyer and Hicks (70). Includes thermal roughness length computation, heat and momentum drag coefficient computation Can be used to output hydrodynamic-related SL quantities (bulk Richardson, turbulent Prandtl number estimation, Reynolds number) - Minor modification in thermcell_dqupdown.F to suit picky compilers - vdifc.F Now takes into account sub-grid gustiness, evaluated from thermals activity (it's proxy being the maximum vertical velocity) - Minor modification in meso_inc_les.F: u* is now taken from the new vdifc and not recomputed from a simple law == 08/08/2011 == AC - Formula correction for the Reynolds in vdif_cd : will affect the thermal roughness length. Results obtained with the precedent formula (previous commit) probably underestimate by about 1K the temperature in the mixing layer. - Added a new subroutine to libf/phymars called surflayer_interpol.F. This routine can be called as a diagnostic for interpolation of horizontal velocity norm and temperature in the surface layer, in 1D or 3D. The output height is controlled by a parameter z_out, to be set in physiq.F. This might be later added to a .def file. z_out is set to 0. by default, resulting in no call to this subroutine. == 16/08/2011 == AC - Minor modification in physiq.F to pass Ch from vdifc to meso_inc_les - Major modification to the formulation of integrals in surflayer_interpol.F Now stable for most cases. Some cases with highly negative Monin Obukhov length remain to be explored. - Added gustiness to the Richardson computation in vdif_cd.F. Gustiness factor is for now of beta=1., after several comparisons with LES aerodynamic conductances. May be subject to a minor change (+/- 0.1) in the near future. (almost transparent for the user) - Minor modifications relative to variables in vdifc.F. - Esthetic change to calltherm_mars.F - Changed the definition for HFX computation in the LES in meso_inc/meso_inc_les.F. New definition yields very similar results to old one and follows a strict definition of what HFX should be. == 24/08/11 == TN Attempts to tune the water cycle by adding outliers + A few structural changes !! * watercap.h is now obsolete and removed -- all is in surfdat.h * watercaptag initialized in surfini.F (up to 7 areas defined) instead of initracer.F - settings proposed by AS commented - experiments by TN decommented. use with caution. * water ice albedo and thermal inertia in callphys.def and inifis.F * water ice albedo in surfini.F * water ice albedo computation in albedocaps.F90 * alb_surfice is now obsolete in physiq.F, albedo_h2o_ice is used instead * frost_albedo_threshold defined in surfdat.h * water ice thermal inertia in soil.F TODO: * calibrate thermal inertia and ice albedo * have a look at subgrid-scale ice with dryness ? == 07/09/2011 == AC - Added new flag for the Richardson-based surface layer : callrichsl, can be changed in callphys.def One should always use the thermals model when using this surface layer model. Somes cases (weakly unstable with low winds), when not using thermals, won't be well represented by the Richardson surface layer. This stands for Mesoscale and Gcm but not for LES model. Correct configs : callrichsl = .true. calltherm = .true. callrichsl = .false. calltherm = .false. callrichsl = .false. calltherm = .true. Previously unstable config : callrichsl = .true. calltherm = .false. - To be able to run without thermals and with the new surface layer, a modification has been made to physiq.F to account for gustiness in GCM and MESOSCALE for negative Richardson, so that : callrichsl = .true. calltherm = .false. can now be used without problems, but is not recommended. - Consequently, callrichsl = .false. is now the default configuration for thermals. We recall the available options in callphys.def for thermals : outptherm = BOOLEAN (.false. by default) : outputs thermals related quantities (lots of diagfi) nsplit_thermals = INTEGER (50 by default in gcm, 2 in mesoscale) : subtimestep for thermals model. It is recommended to use at least 40 in the gcm, and at least 2 in the mesoscale. The user can lower these values but should check it's log for anomalies or errors regarding tracer transport in the thermals, or "granulosity" in the outputs for wmax, lmax and hfmax. == 08/09/11 == AS LMDZ.MARS + MESOSCALE. ---> Setting up a more realistic water ice source at the poles (notably outliers) [[ surfini.F ]] Main changes and bug fixes * reference to comcstfi.h was wrong. big problem because e.g. pi was not known. * commented about a problem to be fixed, due to surfini being called before initracer. * MESOSCALE: put the mesoscale north cap definition into a precompiling flag #MESOSCALE for the moment: if [alb_mean_TES > 0.26 and lat > 70] then outliers (previously done in meso_inc_caps.F) [[ inifis.F ]] Just changed a comment with wrong formatting --> below, only MESOSCALE [[ soil.F ]] if somewhere IT > IT_outliers, then makes it = IT_outliers [[ physiq.F ]] [[ meso_inc/meso_inc_caps.F ]] [[ meso_inc/meso_inc_ini.F ]] meso_inc_caps no longer called. keep for reference for the moment. [[ meso_inc/meso_inc_var.F ]] deleted lines with *_lim variables, now useless == 08/09/11 == EM -Fixed problem about undefined tracer names in 'surfini.F' by calling 'initracer' before 'surfini' in physiq.F == 09/09/11 == AS --> Fixed a problem with .eq. used with booleans in physiq.F [some good picky compilers complain about this] --> Added a warning in inifis about using callrichsl = .false. calltherm = .true. which is not recommended. The new surface layer has been built to go with the new mixing layer scheme (thermals). And anyway it is a much better scheme than the previous one. == 09/09/11 == AC This is a major update for thermals and richardson layer parametrization. This update stabilizes thermals (further studies might show that we can reduce the value of nsplit in gcm. To be tested.), and prevent downdrafts from descending into the surface layer, which was acting as a cold feedback on the thermals. The Richardson surface layer now features different gustiness coefficients for Richardson, heat and momentum so that u* and t* are correctly represented. Upcoming updates will change surflayer_interpol.F90 to implement those changes in the interpolation scheme as well. *************************** IMPORTANT : several parts of the vdifc code might want to use these new definitions for gustiness, u* and t*. exemple : dust devil routines that recompute u* ? lifting routines ? TODO ! ************************** M 289 libf/phymars/thermcell_main_mars.F90 ^-----------------> Added iterations to the velocity / buoyancy / entrainment / detrainment computation to ensure correct convergence. Iteration number is for now set to 4, which is probably too much. This will be changed once several cases are tested. The minimum is probably 2 iterations. M 289 libf/phymars/vdifc.F ^-----------------> Subgrid gustiness parametrization now uses different gustiness beta coefficients for heat and momentum. Comparisons with LES at Exomars landing site, matching u* and teta* suggests values of beta=0.7 for momentum and beta=1.2 for heat, where the formula for large scale horizontal winds in the first layer is : U0^2 = pu^2 + pv^2 + (beta*wmax_th)^2 M 289 libf/phymars/vdif_cd.F ^-----------------> LES data suggests that Richardson number distribution during daytime has a very large standart deviation due to highly negative Richardsons on several gridpoints. As a consequence, the mean Richardson in daytime in the LES is much more negative than in LES. In the gcm, parametrized subgrid turbulence prevents such cases, which can be dangerous in nearly unstable conditions. Hence, we use beta=0.5 instead of one, so that we keep the anti-crazy-hfx function of beta and we increase the norm of negative Richardsons in general for daytime conditions. This is set in conjonction with beta settings for heat and momentum in vdifc. M 289 libf/phymars/meso_inc/meso_inc_les.F ^-----------------> HFX and USTM computations now uses the different betas for heat and momentum. == 21/09/11 == AS --> Added MESOINI precompiler flag so that all fields needed to initialize the mesoscale model are being output in the diagfi.nc file. Previously it was made through a separate physiq.F which needed to be updated every time... --> This is completely transparent to the casual GCM users and only appears in the WRITEDIAGFI section of physiq.F == 21/09/11 == AC Revision on several settings for the thermals model. This version relies on fits done for an article to be published, and is more precise. M 299 libf/phymars/thermcell_main_mars.F90 ^-----------------> Changed downdraft to updraft mass flux ratio from -1.8 to -1.9 Changed first level for downdraft mixing from k=3 to k=2. Only level 1 is non-mixed now. Changed coefficients for downdraft to updraft thermal buoyancy ratios. M 299 libf/phymars/calltherm_mars.F90 ^-----------------> Changed r_aspect_thermals from 2. to 1.5 for the GCM version to better match buoyancy profiles. == 29/09/11 == AS --> To easily explore sensitivity to lifting thresholds: in dustlift.F, ustar_seuil=sqrt(stress/rho) and alpha_lift[dust_mass] can be prescribed through an external stress.def parameter file. --- alpha_lift[dust_number] is computed from alpha_lift[dust_mass] as in initracer.F --- ustar_seuil is more user-friendly than stress because direct comparison with ustar from model --> For the moment this is MESOSCALE only, but potentially useful to everyone == 30/09/11 == TN >> Bug correction in lect_start_archive.F ; in some cases layer(:) was not initialized. == 10/10/2011 == AC *********** This commit aims at increasing the thermals speed. Using these corrections, gcm performances in 64x48x32 using 1 tracer goes from 27.9% elapsed time in thermals to 18.76%. *********** Additional work needs to be done in tracer advection to gain speed in high tracer number configuration. (tracer advection (but not momentum nor temperature) could be decoupled from sub-timestep, as they do not act on the thermals scheme (water vapor is neglected as we use theta and not theta_v, and radiative effect of dust is not computed in the thermals.)) *********** => TOP 5 of routine contributions to gcm runtime : Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls s/call s/call name 18.76 6.33 6.33 960 0.01 0.01 thermcell_main_mars_ 17.19 12.13 5.80 __svml_powf4.A 13.72 16.76 4.63 10369 0.00 0.00 filtreg_ 3.94 18.09 1.33 __intel_new_memset 3.73 19.35 1.26 2880 0.00 0.00 thermcell_dqupdown_ note: thermcell_main_mars_ does call quite a lot power computations (see __svml_powf4.A), but this number will not increase with tracer numbers. *********** => LOG: M 312 libf/phymars/thermcell_main_mars.F90 ^------------------- removed (commented) computations on buoyancy which is purely diagnostic tuned internal convergence loop and added convergence criterion M 312 libf/phymars/thermcell_dqupdown.F90 ^------------------- removed (commented) downdraft-related if-loops (as we do not advect tracers and momentum in downdrafts for now) M 312 libf/phymars/calltherm_mars.F90 ^------------------- removed (commented) diagnostic-related computations changed default thermals spliting and aspect ratio corrected a bug where maximum height was not correctly computed and could result in convective adjustment used in place of thermals when using certains sets of nsplit and r_aspect (was not happening with the baseline version, so that this correction is transparent to users) ******************** == 14/10/2011 == AS + AC - Monin-Obukhov length is now output from surflay_interpol and written in diagfi if z_out not 0. - in calltherm_interface, defaut settings for qtransport_thermals and dtke_thermals == 20/10/2011 == 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). == 21/10/2011 == EM - Corrected small bug in newstart: initracer was not always used and thus some tracer indexes (igm_co2, igcm_h2o_vap,...) were not set. This however means that we now also call inifis from newstart and that we read in flags set in 'callphys.def' (required for sanity checks in initracer). Also adapted 'inichim_readcallphys': removed some obsolescent tests on number of tracers for given combinations of options. == 21/10/2011 == AS - Added possibility for CH4 tracer in tracer.h and initracer.F == 27/10/11 == AS --> Added geticecover.F90 which computes seasonal ice cover given ls, lati(ngrid), long(ngrid) as proposed by T. Titus from TES observations [fitting functions for crocus line] ... output is icecover(ngrid) which value is 0 [no ice cover] or 1 [ice cover] ... no calculations are done for latitudes between -40 and +40 [ice cover is directly set to 0] --> In physiq.F, co2ice is set to a dummy high value to simulate a CO2 cap wherever icecover(ngrid) is 1. This is done at each timestep before newcondens is called. --> For the moment this is MESOSCALE only, but potentially useful to everyone. == 28/10/11 == FL + AS ADDED THE NEW FRAMEWORK FOR PHOTOCHEMISTRY This is not the last version. A new rewritten version of calchim.F [using LAPACK] is yet to be committed. --> A new version for photochemistry routines : *_B.F no longer exists, new routines in aeronomars D 333 libf/aeronomars/photochemist_B.F D 333 libf/aeronomars/init_chimie_B.F A 0 libf/aeronomars/read_phototable.F M 333 libf/aeronomars/calchim.F A 0 libf/aeronomars/photochemistry.F M 333 libf/aeronomars/chimiedata.h --> Changed calls to calchim and watercloud [surfdust and surfice needed] in physiq.F --> Left commented code for outputs in physiq.F [search for FL] --> Added settings which works for 35 levels in inidissip.F according to FL. Commented for the moment. --> Checked compilation and run, looks fine. Note that 'jmars.20101220' is needed. == 02/11/2011 == AC *********** This commit aims at increasing the thermals speed, especially for large tracer number configurations. The idea behind this commit is to advect non-active conserved variables outside of the sub-timestep of the thermals. Because these variables are not used in thermals computation, we can decouple them: momentum: can be decoupled because we assume a constant ratio between horizontal velocity in alimentation layer and maximum vertical velocity in the thermal s. tracer: can be decoupled because we do not take condensation of any tracer into account and hence do not liberate latent heat nor form clouds in the thermal s. temperature: cannot be decoupled (of course) *********** D 336 libf/phymars/thermcell_dqupdown.F90 ^---------------- Deleted and replaced by a simpler version. Notes about downdraft advection are still available from revision 336 of SVN in thermcell_dqu pdown. A 0 libf/phymars/thermcell_dqup.F90 ^---------------- New upward advection for tracers and momentum in thermals. Several changes are done compared to the old approach: - Updraft quantities are not longer computed by making hypothesis on the amount of advected air. - In general, the formalism for updraft computation is much simpler and clearer. - Tracer tendancies are no longer computed using the conservation equation. Instead, we use the divergence of an approximated turbulent flux of the concerned quantity, where downdraft are also neglected. M 336 libf/phymars/thermcell_main_mars.F90 ^---------------- The Main does not call anymore thermcell_dqupdown, which it was doing 2+tracer_number times per subtimestep (140 times per physical step for a 2 tracer config) M 336 libf/phymars/calltherm_mars.F90 ^---------------- Entrainment, detrainment and mass-fluxes are recomputed in the sub-timestep loop. Their final value after iterations is used by the new advection routine to compute tracer and momentum fluxes. *********** Results - Conservation of tracers has been assessed over 1 yr in 1D and found to be comparable to that obtained with the simple convective adjustment. (it actually seems to be better by a factor of 10%!) - GCM speed-up is of about 20% compared to the old thermal configuration, for a 2 tracer case. - Advection of sharp tracer profiles has been successfully observed, similar to the old method. == 07/11/11 == JBM >>> Changed watercloud.F to call two separate routines, simpleclouds.F or improvedclouds.F, which are a simplified and full microphysical scheme for cloud formation, respectively. Removed the tag called "improved" in watercloud.F, and added another tag called "microphys" which is defined in callphys.F instead. Changed routines: callkeys, inifis, physiq, watercloud. >>> Reimplemented the use of typical profiles of dust particle sizes and CCNs in simpleclouds.F. Corrected the previously used analytical CCN profile. Moved ccn_factor to simpleclouds.F, which won't be used in the new microphysical scheme. Changed routines: aeropacity, physiq, simpleclouds, watercloud. >>> Computed rdust at the end of callsedim instead of updatereffrad, except at firstcall. Renamed rfall into rsedcloud and moved it in simpleclouds. Moved nuice_sed to initracer.F and added it to tracer.h. Changed routines: callsedim, physiq, tracer.h, watercloud, initracer, simpleclouds, updatereffrad. >>> Added two tracers for the CCNs. Added the different tests in initracer.F to make sure that, for example, microphys is not used without doubleq, etc. Corrected an inconsistency in callsedim.F, and changed the way r0 is updated. Changes routines: callsedim, inifis, initracer, physiq, testphys1d, tracer.h. >>> Added the ability to have a spatially variable density in newsedim (same method as that used for the radius of sedimentation). Required the addition of one input to newsedim, which is the size of the density variable "rho". Changed routines: callsedim, newsedim. >>> Added an output to aeropacity called "tauscaling", which is a factor to convert dust_mass and dust_number to true quantities, based on tauvis. Removed ccn and qdust from aeropacity, which are obsolete now. >>> Wrote improvedcloud.F which includes all the microphysical scheme, and connected it to the sedimentation scheme. Added and changed routines: callsedim, physiq, growthrate, nuclea, improvedclouds, initracer, watercloud, microphys.h. == 07/11/11 == TN >> Added CCN & dust tracers updates in physiq.F Corrected a bug that can give negative CCN numbers, due to the use of single precision values (only 6 decimals) whereas up to 10E+10 CCN can be formed or disappears... >> Corrected physical bug that causes h2o_vap or h2o_ice to be negative in improvedclouds.F. >> Corrected physical bug that causes CCN & dust tracers to be negative in improvedclouds.F when all ice sublimates and releases dust >> Added parameter contact mteta in callphys.def Default value is still 0.95, see inifis.F >> Changed tendancy computation for dust_number in improvedclouds.F that was not the right one. Indeed, the scavenged dust_number tracer is computed from the dust_mass one, and its tendancy before scavenging must be taken into account to compute its scavenging's tendancy. == 09/11/11 == AS Added a more recent version of concentrations.F by FL
