3MODULE etat0phys

5  !*******************************************************************************
6  ! Purpose: Create physical initial state using atmospheric fields from a
7  !          database of atmospheric to initialize the model.
8  !-------------------------------------------------------------------------------
9  ! Comments:
10
11  !    *  This module is designed to work for Earth (and with ioipsl)
12
13  !    *  etat0phys_netcdf routine can access to NetCDF data through subroutines:
14  !         "start_init_phys" for variables contained in file "ECPHY.nc":
15  !            'ST'     : Surface temperature
16  !            'CDSW'   : Soil moisture
17  !         "start_init_orog" for variables contained in file "Relief.nc":
18  !            'RELIEF' : High resolution orography
19
20  !    * The land mask and corresponding weights can be:
21  !      1) computed using the ocean mask from the ocean model (to ensure ocean
22  !         fractions are the same for atmosphere and ocean) for coupled runs.
23  !         File name: "o2a.nc"  ;  variable name: "OceMask"
24  !      2) computed from topography file "Relief.nc" for forced runs.
25
26  !    * Allowed values for read_climoz flag are 0, 1 and 2:
27  !      0: do not read an ozone climatology
28  !      1: read a single ozone climatology that will be used day and night
29  !      2: read two ozone climatologies, the average day and night climatology
30  !         and the daylight climatology
31  !-------------------------------------------------------------------------------
32  !    * There is a big mess with the longitude size. Should it be iml or iml+1 ?
33  !  I have chosen to use the iml+1 as an argument to this routine and we declare
34  !  internaly smaller fields when needed. This needs to be cleared once and for
35  !  all in LMDZ. A convention is required.
