In procedure clmain, remove local variable ykmq, not used (not used in LMDZ either). Remove its computation in yamada4. In procedure yamada4, remove dummy argument cd, not used.
Use iflag_pbl from module conf_phys in yamada4 instead of getting it as argument. In clvent, simplifications using the fact that zx_alf2 = 0 and zx_alf1 = 1 (discarding the possibility to change this). In physiq, no need for temporary variables z[uv]strph: compute actual arguments of aaam_bud directly.
Bug fix in dynetat0: phisinit to phis. gcm explodes (stops in hgardfou) in less than one day with iflag_pbl = 7 (Mellor and Yamada 2.0 Fournier) and 11 (corresponding to iflag_pbl = 31 in LMDZ, call to vdif_kcay). So remove those choices. Not much used in LMDZ either. Remaining useful choices are iflag = 0, 1, 6, 8, 9. Remove procedure yamada, which was not used.
Rename phisinit to phis in restart.nc: clearer, same name as Fortran variable. In aaam_bud, use rlat and rlon from phyetat0_m instead of having these module variables associated to actual arguments in physiq. In clmain, too many wind variables make the procedure hard to understand. Use yu(:knon, 1) and yv(:knon, 1) instead of u1lay(:knon) and v1lay(:knon). Note that when yu(:knon, 1) and yv(:knon, 1) are used as actual arguments, they are probably copied to new arrays since the elements are not contiguous. Rename yu10m to wind10m because this is the norm of wind vector, not its zonal component. Rename yustar to ustar. Rename uzon and vmer to u1 and v1 since these are wind components at first layer and u1 and v1 are the names of corresponding dummy arguments in stdlevvar. In clmain, rename yzlev to zlev. In clmain, screenc, stdlevvar and coefcdrag, remove the code corresponding to zxli true (not used in LMDZ either). Subroutine ustarhb becomes a function. Simplifications using the fact that zx_alf2 = 0 and zx_alf1 = 1 (discarding the possibility to change this). In procedure vdif_kcay, remove unused dummy argument plev. Remove useless computations of sss and sssq. In clouds_gno, exp(100.) would overflow in single precision. Set maximum to exp(80.) instead. In physiq, use u(:, 1) and v(:, 1) as arguments to phytrac instead of creating ad hoc variables yu1 and yv1. In stdlevvar, rename dummy argument u_10m to wind10m, following the corresponding modification in clmain. Simplifications using the fact that ok_pred = 0 and ok_corr = 1 (discarding the possibility to change this).
Removed argument icbmax of cv30_feed, not used in cv_driver (not used in LMDZ either). Clearer to have iflag1 = 0 in cv30_feed than in cv_driver. Clearer to have iflag1 = 42 in cv30_uncompress than in cv_driver. Removed argument iflag of cv30_compress. Since there is iflag1 = 42 in cv30_uncompress, iflag1 that comes out of cv_driver is disconnected from iflag1 computed by cv30_feed and cv30_trigger. Removed some references to convect3 and convect4 in comments. This program derives from the convect3 version, we do not need to know about other versions. Bug fix in cv30_undilute1: icbs1 was not made >= 2.
Moved variables date0, deltat, datasz_max, ncvar_ids, point, buff_pos, buffer, regular from module histcom_var to modules where they are defined. Removed procedure ioipslmpp, useless for a sequential program. Added argument datasz_max to histwrite_real (to avoid circular dependency with histwrite). Removed useless variables and computations everywhere. Changed real litteral constants from default kind to double precision in lwb, lwu, lwvn, sw1s, swtt, swtt1, swu. Removed unused arguments: paer of sw, sw1s, sw2s, swclr; pcldsw of sw1s, sw2s; pdsig, prayl of swr; co2_ppm of clmain, clqh; tsol of transp_lay; nsrf of screenp; kcrit and kknu of gwstress; pstd of orosetup. Added output of relative humidity.
Sources inside, compilation outside.
Removed procedure fxyhyper. Useless intermediary between inigeom and fxhyp, fyhyp. Removed argument yprimv of fyhyp, not used in inigeom. Downgraded rlonm025 and rlonp025 from arguments to local variables of fxhyp, not used in inigeom. Downgraded arguments champmin, champmax of fxhyp and fyhyp to local variables: print them in fxhyp and fyhyp instead of fxyhyper. Removed arguments xzoomdeg, grossism, dzooma, tau of fxhyp. Use directly module variables clon, grossismx, dzoomx, taux instead. Removed arguments yzoomdeg, grossism, dzooma, tau of fyhyp. Use directly module variables clat, grossismy, dzoomy, tauy instead. In procedure yamada4, l0 does not need the save attribute. It is defined at each call.
In file grilles_gcm.nc, renamed variable phis to orog, deleted variable presnivs. Removed variable bug_ozone from module clesphys. In procedure ozonecm, moved computation of sint and cost out of the loops on horizontal position and vertical level. Inverted the order of the two loops. We can then move all computations from slat to aprim out of the loop on vertical levels. Created variable slat2, following LMDZ. Moved the limitation of column-density of ozone in cell at 1e-12 from radlwsw to ozonecm, following LMDZ. Removed unused arguments u, albsol, rh, cldfra, rneb, diafra, cldliq, pmflxr, pmflxs, prfl, psfl of phytrac. In procedure yamada4, for all the arrays, replaced the dimension klon by ngrid. At the end of the procedure, for the computation of kmn,kn, kq and q2, changed the upper limit of the loop index from klon to ngrid. In radlwsw, for the calculation of pozon, removed the factor paprs(iof+i, 1)/101325, as in LMDZ. In procedure sw, removed the factor 101325.0/PPSOL(JL), as in LMDZ.
Created procedure test_disvert (following LMDZ). Added procedures hybrid and funcd in module disvert_m. Upgraded compute_ab from internal procedure of disvert to module procedure. Added variables y, ya in module disvert_m. Upgraded s from local variable of procedure disvert to module variable. Renamed allowed value of variable vert_sampling in procedure disvert from "read" to "read_hybrid". Added possibility to read pressure values, value "read_pressure". Replaced vertical distribution for value "param" by the distribution "strato_correct" from LMDZ (but kept the value "param"). In case "tropo", replaced 1 by dsigmin (following LMDZ). In case "strato", replaced 0.3 by dsigmin (following LMDZ). Changed computation of bp in procedure compute_ab. Removed debugindex case in clmain. Removed useless argument rlon of procedure clmain. Removed useless variables ytaux, ytauy of procedure clmain. Removed intermediary variables tsol, qsol, tsolsrf, tslab in procedure etat0. Removed variable ok_veget:. coupling with the model Orchid is not possible. Removed variable ocean: modeling an ocean slab is not possible. Removed useless variables tmp_rriv and tmp_rcoa from module interface_surf. Moved initialization of variables da, mp, phi in procedure physiq to to inside the test iflag_con >= 3.
Changed all ".f90" suffixes to ".f".
Moved everything out of libf.
Changed handling of compiler in compilation system. Removed the prefix letters "y", "p", "t" or "z" in some names of variables. Replaced calls to NetCDF by calls to NetCDF95. Extracted "ioget_calendar" procedures from "calendar.f90" into a separate file. Extracted to a separate file, "mathop2.f90", procedures that were not part of the generic interface "mathop" in "mathop.f90". Removed computation of "dq" in "bilan_dyn", which was not used. In "iniadvtrac", removed schemes 20 Slopes and 30 Prather. Was not compatible with declarations of array sizes. In "clcdrag", "ustarhb", "vdif_kcay", "yamada4" and "coefkz", changed the size of some arrays from "klon" to "knon". Removed possible call to "conema3" in "physiq". Removed unused argument "cd" in "yamada".
Split "thermcell.f" and "cv3_routines.f". Removed copies of files that are now in "L_util". Moved "mva9" and "diagetpq" to their own files. Unified variable names across procedures.
Created rule for "compare_sampl_*" files in "Documentation/Manuel_LMDZE.texfol/Graphiques/GNUmakefile". Extracted "qcheck", "radiornpb", "minmaxqfi" into separate files. Read pressure coordinate of ozone coefficients once per run instead of every day. Added some "intent" attributes. Added argument "nq" to "ini_histday". Replaced calls to "gr_fi_ecrit" by calls to "gr_phy_write_2d". "Sigma_O3_Royer" is written to "histday.nc" only if "nq >= 4". Moved "ini_histrac" to module "ini_hist". Compute "zmasse" in "physiq", pass it to "phytrac". Removed computations of "pftsol*" and "ppsrf*" in "phytrac". Do not use variable "rg" from module "YOMCST" in "TLIFT".
-- Minor modification of input/output: Created procedure "read_logic". Variables of module "logic" are read by "read_logic" instead of "conf_gcm". Variable "offline" of module "conf_gcm" is read from namelist instead of "*.def". Deleted arguments "dtime", "co2_ppm_etat0", "solaire_etat0", "tabcntr0" and local variables "radpas", "tab_cntrl" of "phyetat0". "phyetat0" does not read "controle" in "startphy.nc" any longer. "phyetat0" now reads global attribute "itau_phy" from "startphy.nc". "phyredem" does not create variable "controle" in "startphy.nc" any longer. "phyredem" now writes global attribute "itau_phy" of "startphy.nc". Deleted argument "tabcntr0" of "printflag". Removed diagnostic messages written by "printflag" for comparison of the variable "controle" of "startphy.nc" and the variables read from "*.def" or namelist input. -- Removing unwanted functionality: Removed variable "lunout" from module "iniprint", replaced everywhere by standard output. Removed case "ocean == 'couple'" in "clmain", "interfsurf_hq" and "physiq". Removed procedure "interfoce_cpl". -- Should not change anything at run time: Automated creation of graphs in documentation. More documentation on input files.
