1MODULE etat0phys
2!
3!*******************************************************************************
4! Purpose: Create physical initial state using atmospheric fields from a
5!          database of atmospheric to initialize the model.
6!-------------------------------------------------------------------------------
7! Comments:
8!
9!    *  This module is designed to work for Earth (and with ioipsl)
10!
11!    *  etat0phys_netcdf routine can access to NetCDF data through subroutines:
12!         "start_init_phys" for variables contained in file "ECPHY.nc":
13!            'ST'     : Surface temperature
14!            'CDSW'   : Soil moisture
15!         "start_init_orog" for variables contained in file "Relief.nc":
16!            'RELIEF' : High resolution orography
17!
18!    * The land mask and corresponding weights can be:
19!      1) computed using the ocean mask from the ocean model (to ensure ocean
20!         fractions are the same for atmosphere and ocean) for coupled runs.
21!         File name: "o2a.nc"  ;  variable name: "OceMask"
22!      2) computed from topography file "Relief.nc" for forced runs.
23!
24!    * Allowed values for read_climoz flag are 0, 1 and 2:
25!      0: do not read an ozone climatology
26!      1: read a single ozone climatology that will be used day and night
27!      2: read two ozone climatologies, the average day and night climatology
28!         and the daylight climatology
29!-------------------------------------------------------------------------------
30!    * There is a big mess with the longitude size. Should it be iml or iml+1 ?
31!  I have chosen to use the iml+1 as an argument to this routine and we declare
32!  internaly smaller fields when needed. This needs to be cleared once and for
33!  all in LMDZ. A convention is required.
