Rename module dimens_m to dimensions.
Move Sources/* to root directory.
Moved variables from module com_io_dyn to module inithist_m, where they are defined. Split grid_atob.f into grille_m.f and dist_sphe.f. Extracted ASCCI art to documentation. In grille_m, use automatic arrays instead of maximum size. In grille_m, instead of printing data for every problematic point, print a single diagnostic message. Removed variables top_height, overlap, lev_histhf, lev_histday, lev_histmth, type_run, ok_isccp, ok_regdyn, lonmin_ins, lonmax_ins, latmin_ins, latmax_ins of module clesphys, not used. Removed variable itap of module histwrite_phy_m, not used. There is a variable itap in module time_phylmdz. Added output of tro3. In physiq, no need to compute wo at every time-step, since we only use it in radlwsw.
In invert_zoom_x, call rtsafe instead of the equivalent coding that was there. funcd needs to access a[0-4] and abs_y so we upgrade a[0-4] from arguments of coefpoly to variables of module coefpoly_m and abs_y from local variable of invert_zoom_x to private variable of module invert_zoom_x_m. Removed unused arguments t10m and q10m of hbtm.
dynetat0 read rlonu, rlatu, rlonv, rlatv, cu_2d, cv_2d, aire_2d from "start.nc" and then these variables were overwritten by inigeom. Corrected this. Now, inigeom does not compute rlonu, rlatu, rlonv and rlatv. Moreover, cu_2d, cv_2d, aire_2d are not written to "restart.nc". Since xprimu, xprimv, xprimm025, xprimp025, rlatu1, rlatu2, yprimu1, yprimu2 are computed at the same time as rlonu, rlatu, rlonv, rlatv, and since it would not be convenient to separate those computations, we decide to write xprimu, xprimv, xprimm025, xprimp025, rlatu1, rlatu2, yprimu1, yprimu2 into "restart.nc", read them from "start.nc" and not compute them in inigeom. So, in summary, "start.nc" contains all the coordinates and their derivatives, and inigeom only computes the 2D-variables. Technical details: Moved variables rlatu, rlonv, rlonu, rlatv, xprimu, xprimv from module comgeom to module dynetat0_m. Upgraded local variables rlatu1, yprimu1, rlatu2, yprimu2, xprimm025, xprimp025 of procedure inigeom to variables of module dynetat0_m. Removed unused local variable yprimu of procedure inigeom and corresponding argument yyprimu of fyhyp. Moved variables clat, clon, grossismx, grossismy, dzoomx, dzoomy, taux, tauy from module serre to module dynetat0_m (since they are read from "start.nc"). The default values are now defined in read_serre instead of in the declarations. Changed name of module serre to read_serre_m, no more module variable here. The calls to fxhyp and fyhyp are moved from inigeom to etat0. Side effects in programs other than gcm: etat0 and read_serre write variables of module dynetat0; the programs test_fxyp and test_inter_barxy need more source files. Removed unused arguments len and nd of cv3_tracer. Removed unused argument PPSOL of LWU. Bug fix in test_inter_barxy: forgotten call to read_serre.
Sources inside, compilation outside.
Renamed procedure fxhyp_loop_ik to invert_zoom_x. Bug fix. clat is now in rad so there should be no conversion in fyhyp. (This bug had an effect only if clat was /= 0.) No need for heavyside to be double precision. Removed variable tnom of module iniadvtrac_m. Was redundant with tname.
In procedure fxhyp, extracted the body of the loop on ik into a new procedure: fxhyp_loop_ik. dzoomx and dzoomy must now be fractions of the entire range, they cannot be ranges in degrees or rad. In fxhyp, force Xf(2 * nmax) = pi_d instead of possibly doing it in fxhyp_loop_ik. In fxhyp_loop_ik, when testing whether xvrai is between -pi and pi, changed the boundaries from -pi - 0.1 to - pi_d - 1d-5 and from pi + 0.1 to pi_d + 1d-5. This reveals a misconception of the code. Therefore, this version does not work.
In procedure fxhyp, removed the possibility to set scal180 to false. The useful lower bound of fhyp and xxpr is not 0. It does not make sense to give the save attribute to is2 since fxhyp is only called one per run. Bug fix: is2 could be used without being defined. The bug did not appear because is2 had the save attribute so it was initialized at 0.
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.
Removed 8 first arguments of fxyhyper, use variables of module serre instead. Moved reading of variables of module serre from procedure conf_gcm to new procedure read_serre. In guide, added conditions to avoid useless calls to tau2alpha and writefield. Bugfix: offline corresponds to alpha = 1. Open only one NetCDF file to read number of vertical levels. In tau2alpha, added conditions to avoid useless computations of dxdyu and dxdyv. gamma is not needed for a regular grid.
Module pressure_var is now only used in gcm. Created local variables pls and p3d in etat0, added argument p3d to regr_pr_o3. In leapfrog, moved computation of p3d and exner function immediately after integrd, for clarity (does not change the execution). Removed unused arguments: ntra, tra1 and tra of cv3_compress; ntra, tra and traent of cv3_mixing; ntra, ftra, ftra1 of cv3_uncompress; ntra, tra, trap of cv3_unsat; ntra, tra, trap, traent, ftra of cv3_yield; tra, tvp, pbase, bbase, dtvpdt1, dtvpdq1, dplcldt, dplcldr, ntra of concvl; ndp1, ntra, tra1 of cv_driver Removed argument d_tra and computation of d_tra in concvl. Removed argument ftra1 and computation of ftra1 in cv_driver. ftra1 was just set to 0 in cv_driver, associated to d_tra in concvl, and set again to zero in concvl.
Changed all ".f90" suffixes to ".f".
Converted to free source form files which were still in fixed source form. The conversion was done using the polish mode of the NAG Fortran Compiler. In addition to converting to free source form, the processing of the files also: -- indented the code (including comments); -- set Fortran keywords to uppercase, and set all other identifiers to lower case; -- added qualifiers to end statements (for example "end subroutine conflx", instead of "end"); -- changed the terminating statements of all DO loops so that each loop ends with an ENDDO statement (instead of a labeled continue).
Moved everything out of libf.
No reason to call inidissip in ce0l. In inidissip, set random seed to 1 beacuse PGI compiler does not accept all zeros. dq was computed needlessly in caladvtrac. Arguments masse and dq of calfis not used. Replaced real*8 by double precision. Pass arrays with inverted order of vertical levels to conflx instead of creating local variables for this inside conflx.
