MODULE startvar ! !******************************************************************************* ! !------------------------------------------------------------------------------- ! Purpose: Access data from the database of atmospheric to initialize the model. !------------------------------------------------------------------------------- ! Comments: ! ! * This module is designed to work for Earth (and with ioipsl) ! ! * There are three ways to acces data, depending on the type of field ! which needs to be extracted. In any case the call should come after a restget ! and should be of the type : CALL startget(...) ! ! - A 1D variable on the physical grid : ! CALL startget_phys1d((varname, iml, jml, lon_in, lat_in, nbindex, & ! champ, val_exp, jml2, lon_in2, lat_in2, ibar ) ! ! - A 2D variable on the dynamical grid : ! CALL startget_phys2d(varname, iml, jml, lon_in, lat_in, & ! champ, val_exp, jml2, lon_in2, lat_in2, ibar ) ! ! - A 3D variable on the dynamical grid : ! CALL startget_dyn((varname, iml, jml, lon_in, lat_in, lml, pls, workvar, & ! champ, val_exp, jml2, lon_in2, lat_in2, ibar ) ! ! * Data needs to be in NetCDF format ! ! * Variables should have the following names in the files: ! 'RELIEF' : High resolution orography ! 'ST' : Surface temperature ! 'CDSW' : Soil moisture ! 'Z' : Surface geopotential ! 'SP' : Surface pressure ! 'U' : East ward wind ! 'V' : Northward wind ! 'TEMP' : Temperature ! 'R' : Relative humidity ! ! * There is a big mess with the longitude size. Should it be iml or iml+1 ? ! I have chosen to use the iml+1 as an argument to this routine and we declare ! internaly smaller fields when needed. This needs to be cleared once and for ! all in LMDZ. A convention is required. !------------------------------------------------------------------------------- USE ioipsl IMPLICIT NONE PRIVATE PUBLIC startget_phys2d, startget_phys1d, startget_dyn !
