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.
