In practice c The calculations are only performed for the first "nlaylte" c parameters (nlaylte is calculated by subroutine "nlthermeq" c and stored in module "yomlw_h"). c c The purpose of this subroutine is to: c 1) Make some initial calculation at first call c 2) Split the calculation in several sub-grid c ("sub-domain") to save memory and c be able run on a workstation at high resolution c The sub-grid size is defined in dimradmars_mod c 3) Compute the 3D scattering parameters depending on the c size distribution of the different tracers (added by JBM) c 4) call "lwmain" and "swmain" c c c authors: c ------ c Francois Forget / Christophe Hourdin / J.-B. Madeleine (2009) c c c 3D scattering scheme user's guide (J.-B. Madeleine) c --------------------------------- c c This routine has been modified to take into account 3D, time c dependent scattering properties of the aerosols. c---- The look-up tables that contain the scattering parameters c of a given tracer, for different sizes, are read by SUAER.F90. c The names of the corresponding ASCII files have to be set in c this subroutine (file_id variable), and files must be in the c directory specified in datafile_mod. Please make sure that the c ASCII files are correctly written, and that the range c of particle sizes is consistent with what you would expect. c---- SUAER.F90 is in charge of reading the ASCII files and averaging c the scattering parameters in each GCM channel, using the three last c equations of Forget et al. 1998 (GRL 25, No.7, p.1105-1108). c---- These look-up tables, loaded during the firstcall, are then c constantly used by the subroutine "aeroptproperties.F" to compute, c online, the 3D scattering parameters, based on the size distribution c (reffrad and nueffrad) of the different tracers, in each grid box. c These 3D size distributions are loaded by the "updatereffrad.F" c subroutine. A log-normal distribution is then assumed in c "aeroptproperties.F", along with a Gauss-Legendre integration. c---- The optical depth at the visible reference wavelength (set in c SUAER.F90, after the file_id variable) is then computed by c the subroutine "aeropacity.F", by using the size and spatial c distribution of the corresponding tracer. This connection has to c be implemented in "aeropacity.F" when adding a new tracer. To do so, c one can use equation 2 of Forget et al. 1998 (Icarus 131, p.302-316). c---- The resulting variables "aerosol", "QVISsQREF3d", "omegaVIS3d" and c "gVIS3d" (same in the infrared) are finally used by lwmain.F and c swmain.F to solve the radiative transfer equation. c c changes: c ------- c c > SRL 7/2000 c c This version has been modified to only calculate radiative tendencies c over layers 1..NFLEV (set in dimradmars_mod). Returns zero for higher c layers, if any. c In other routines, nlayer -> nflev. c Routines affected: lwflux, lwi, lwmain, lwxb, lwxd, lwxn. c c > J.-B. Madeleine 10W12 c This version uses the variable's splitting, which can be usefull c when performing very high resolution simulation like LES. c c ---------- c Here, solar band#1 is spectral interval between "long1vis" and "long2vis" c set in dimradmars_mod c Here, solar band#2 is spectral interval between "long2vis" and "long3vis" c set in dimradmars_mod c c input: c ----- c icount counter of call to subroutine physic by gcm c ngrid number of gridpoint of horizontal grid c nlayer Number of layer c nq Number of tracer c ls Solar longitude (Ls) , radian c zday Date (time since Ls=0, in martian days) c pq(ngrid,nlayer,nq) Advected fields c c albedo (ngrid,2) hemispheric surface albedo c albedo (i,1) : mean albedo for solar band#1 c (see below) c albedo (i,2) : mean albedo for solar band#2 c (see below) c emis Thermal IR surface emissivity (no unit) c mu0(ngrid) cos of solar zenith angle c (=1 when sun at zenith) c pplay(ngrid,nlayer) pressure (Pa) in the middle of each layer c pplev(ngrid,nlayer+1) pressure (Pa) at boundaries of each layer c pt(ngrid,nlayer) atmospheric temperature in each layer (K) c tsurf(ngrid) surface temperature (K) c fract(ngrid) day fraction of the time interval c =1 during the full day ; =0 during the night c declin latitude of subsolar point c dist_sol sun-Mars distance (AU) c igout coordinate of analysed point for debugging c reffrad(ngrid,nlayer,naerkind) Aerosol effective radius c nueffrad(ngrid,nlayer,naerkind) Aerosol effective variance c c output: c ------- c dtlw (ngrid,nlayer) longwave (IR) heating rate (K/s) c dtsw(ngrid,nlayer) shortwave (Solar) heating rate (K/s) c fluxsurf_lw(ngrid) surface downward flux tota LW (thermal IR) (W.m-2) c fluxsurf_sw(ngrid,1) surface downward flux SW for solar band#1 (W.m-2) c fluxsurf_sw(ngrid,2) surface downward flux SW for solar band#2 (W.m-2) c c fluxtop_lw(ngrid) outgoing upward flux tota LW (thermal IR) (W.m-2) c fluxtop_sw(ngrid,1) outgoing upward flux SW for solar band#1 (W.m-2) c fluxtop_sw(ngrid,2) outgoing upward flux SW for solar band#2 (W.m-2) c tauref Prescribed mean column optical depth at 610 Pa c tau Column total visible dust optical depth at each point c aerosol(ngrid,nlayer,naerkind) aerosol extinction optical depth c at reference wavelength "longrefvis" set c in dimradmars_h , in each layer, for one of c the "naerkind" kind of aerosol optical c properties. c======================================================================= c c Declarations : c ------------- c #include "callkeys.h" c----------------------------------------------------------------------- c Input/Output c ------------ INTEGER,INTENT(IN) :: icount INTEGER,INTENT(IN) :: ngrid,nlayer,nq INTEGER,INTENT(IN) :: igout REAL,INTENT(IN) :: pq(ngrid,nlayer,nq) REAL,INTENT(IN) :: tauscaling(ngrid) !
