| 9 | ! * This module is designed to work for Earth (and with ioipsl) |
|---|
| 10 | |
|---|
| 11 | ! * etat0dyn_netcdf routine can access to NetCDF data through the following |
|---|
| 12 | ! routine (to be called after restget): |
|---|
| 13 | ! CALL startget_dyn3d(varname, lon_in, lat_in, pls, workvar,& |
|---|
| 14 | ! champ, lon_in2, lat_in2) |
|---|
| 15 | |
|---|
| 16 | ! * Variables should have the following names in the NetCDF files: |
|---|
| 17 | ! 'U' : East ward wind (in "ECDYN.nc") |
|---|
| 18 | ! 'V' : Northward wind (in "ECDYN.nc") |
|---|
| 19 | ! 'TEMP' : Temperature (in "ECDYN.nc") |
|---|
| 20 | ! 'R' : Relative humidity (in "ECDYN.nc") |
|---|
| 21 | ! 'RELIEF' : High resolution orography (in "Relief.nc") |
|---|
| 22 | |
|---|
| 23 | ! * The land mask and corresponding weights can be: |
|---|
| 24 | ! 1) already known (in particular if etat0dyn has been called before) ; |
|---|
| 25 | ! in this case, ANY(masque(:,:)/=-99999.) = .TRUE. |
|---|
| 26 | ! 2) computed using the ocean mask from the ocean model (to ensure ocean |
|---|
| 27 | ! fractions are the same for atmosphere and ocean) for coupled runs. |
|---|
| 28 | ! File name: "o2a.nc" ; variable name: "OceMask" |
|---|
| 29 | ! 3) computed from topography file "Relief.nc" for forced runs. |
|---|
| 30 | |
|---|
| 31 | ! * There is a big mess with the longitude size. Should it be iml or iml+1 ? |
|---|
| 32 | ! I have chosen to use the iml+1 as an argument to this routine and we declare |
|---|
| 33 | ! internaly smaller fields when needed. This needs to be cleared once and for |
|---|
| 34 | ! all in LMDZ. A convention is required. |
