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