5	!
6	!
7	! There are three ways to access data from the database of atmospheric data which
8	! can be used to initialize the model. This depends on the type of field which needs
9	! to be extracted. In any case the call should come after a restget and should be of the type :
10	! CALL startget(...)
11	!
12	! We will details the possible arguments to startget here :
13	!
14	! - A 2D variable on the dynamical grid :
15	! CALL startget(varname, iml, jml, lon_in, lat_in, champ, val_ex, jml2, lon_in2, lat_in2, interbar )
16	!
17	! - A 1D variable on the physical grid :
18	! CALL startget(varname, iml, jml, lon_in, lat_in, nbindex, champ, val_exp, jml2, lon_in2, lat_in2, interbar )
19	!
20	!
21	! - A 3D variable on the dynamical grid :
22	! CALL startget(varname, iml, jml, lon_in, lat_in, lml, pls, workvar, champ, val_exp, jml2, lon_in2, lat_in2, interbar )
23	!
24	!
25	! There is special constraint on the atmospheric data base except that the
26	! the data needs to be in netCDF and the variables should have the the following
27	! names in the file :
28	!
29	! 'RELIEF' : High resolution orography
30	! 'ST' : Surface temperature
31	! 'CDSW' : Soil moisture
32	! 'Z' : Surface geopotential
33	! 'SP' : Surface pressure
34	! 'U' : East ward wind
35	! 'V' : Northward wind
36	! 'TEMP' : Temperature
37	! 'R' : Relative humidity
