startvar.F90

Last change on this file was 1425, checked in by lguez, 14 years ago

Replaced Numerical Recipes procedures for spline interpolation (not in
the public domain) by procedures from the Pchip package in the Slatec
library. This only affects the program "ce0l", not the program
"gcm". Tested on Brodie SX8 with "-debug" and "-prod", "-parallel
none" and "-parallel mpi". "start.nc" and "limit.nc" are
changed. "startphy.nc" is not changed. The relative change is of order
1e-7 or less. The revision makes the program faster (tested on Brodie
with "-prod -d 144x142x39", CPU time is 38 s, instead of 54
s). Procedures from Slatec are untouched, except for
"i1mach.F". Created procedures "pchfe_95" and "pchsp_95" which are
wrappers for "pchfe" and "pchsp" from Slatec. "pchfe_95" and
"pchsp_95" have a safer and simpler interface.

Replaced "make" by "sxgmake" in "arch-SX8_BRODIE.fcm". Added files for
compilation by FCM with "g95".

In "arch-linux-32bit.fcm", replaced "pgf90" by "pgf95". There was no
difference between "dev" and "debug" so added "-O1" to "dev". Added
debugging options. Removed "-Wl,-Bstatic
-L/usr/lib/gcc-lib/i386-linux/2.95.2", which usually produces an error
at link-time.

Bash is now ubiquitous while KornShell? is not so use Bash instead of
KornShell? in FCM.

Replaced some statements "write(6,*)" by "write(lunout,*)". Replaced
"stop" by "stop 1" in the case where "abort_gcm" is called with "ierr
/= 0". Removed "stop" statements at the end of procedures
"limit_netcdf" and main program "ce0l" (why not let the program end
normally?).

Made some arrays automatic instead of allocatable in "start_inter_3d".

Zeroed "wake_pe", "fm_therm", "entr_therm" and "detr_therm" in
"dyn3dpar/etat0_netcdf.F90". The parallel and sequential results of
"ce0l" are thus identical.

11	! Purpose: Access data from the database of atmospheric to initialize the model.
12	!-------------------------------------------------------------------------------
13	! Comments:
14	!
15	! * This module is designed to work for Earth (and with ioipsl)
16	!
17	! * There are three ways to acces data, depending on the type of field
18	! which needs to be extracted. In any case the call should come after a restget
19	! and should be of the type : CALL startget(...)
20	!
21	! - A 1D variable on the physical grid :
22	! CALL startget_phys1d((varname, iml, jml, lon_in, lat_in, nbindex, &
23	! champ, val_exp, jml2, lon_in2, lat_in2, ibar )
24	!
25	! - A 2D variable on the dynamical grid :
26	! CALL startget_phys2d(varname, iml, jml, lon_in, lat_in, &
27	! champ, val_exp, jml2, lon_in2, lat_in2, ibar )
28	!
29	! - A 3D variable on the dynamical grid :
30	! CALL startget_dyn((varname, iml, jml, lon_in, lat_in, lml, pls, workvar, &
31	! champ, val_exp, jml2, lon_in2, lat_in2, ibar )
32	!
33	! * Data needs to be in NetCDF format
34	!
35	! * Variables should have the following names in the files:
36	! 'RELIEF' : High resolution orography
37	! 'ST' : Surface temperature
38	! 'CDSW' : Soil moisture
39	! 'Z' : Surface geopotential
40	! 'SP' : Surface pressure
41	! 'U' : East ward wind
42	! 'V' : Northward wind
43	! 'TEMP' : Temperature
44	! 'R' : Relative humidity
45	!
46	! * There is a big mess with the longitude size. Should it be iml or iml+1 ?
47	! I have chosen to use the iml+1 as an argument to this routine and we declare
48	! internaly smaller fields when needed. This needs to be cleared once and for
49	! all in LMDZ. A convention is required.
