| 3 | !******************************************************************************* |
|---|
| 4 | ! Purpose: Create physical initial state using atmospheric fields from a |
|---|
| 5 | ! database of atmospheric to initialize the model. |

|---|
| 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. |
