Functions/Subroutines

subroutine, public module_radiation_driver::radupdate (idate, jdate, deltsw, deltim, lsswr, me, slag, sdec, cdec, solcon)
 This subroutine checks and updates time sensitive data used by radiation computations. This subroutine needs to be placed inside the time advancement loop but outside of the horizontal grid loop. It is invoked at radiation calling frequncy but before any actual radiative transfer computations. More...
 
subroutine, public module_radiation_driver::grrad (prsi, prsl, prslk, tgrs, qgrs, tracer, vvl, slmsk, xlon, xlat, tsfc, snowd, sncovr, snoalb, zorl, hprim, alvsf, alnsf, alvwf, alnwf, facsf, facwf, fice, tisfc, sinlat, coslat, solhr, jdate, solcon, cv, cvt, cvb, fcice, frain, rrime, flgmin, icsdsw, icsdlw, ntcw, ncld, ntoz, NTRAC, NFXR, dtlw, dtsw, lsswr, lslwr, lssav, uni_cld, lmfshal, lmfdeep2, IX, IM, LM, me, lprnt, ipt, kdt, deltaq, sup, cnvw, cnvc, htrsw, topfsw, sfcfsw, dswcmp, uswcmp, sfalb, coszen, coszdg, htrlw, topflw, sfcflw, tsflw, semis, cldcov, fluxr , htrlw0, htrsw0, htrswb, htrlwb )
 This subroutine is the driver of main radiation calculations. It sets up column profiles, such as pressure, temperature, moisture, gases, clouds, aerosols, etc., as well as surface radiative characteristics, such as surface albedo, and emissivity. The call of this subroutine is placed inside both the time advancing loop and the horizontal grid loop. More...

subroutine, public module_radiation_driver::radinit (si, NLAY, me)
 This subroutine initialize a model's radiation process through calling of specific initialization subprograms that directly related to radiation calculations. This subroutine needs to be invoked only once at the start stage of a model's run, and the call is placed outside of both the time advancement loop and horizontal grid loop. More...
