| 2 | ! MODULE globgrd : This module is dedicated to managing the spatial grid of the forcing. It can either read a file |
---|
| 3 | ! containing the grid information, as is the case for WRF forcing, or obtain the grid from the forcing files. |
---|
| 4 | ! The module has also the possibility to create a grid description files for certain applications like |
---|
| 5 | ! for instance in a coupling of ORCHIDEE through OASIS. |
---|
| 6 | ! For this purpose the module provides 4 subroutines : |
---|
| 7 | ! globgrd_getdomsz : This routine allows to get the domain size of the forcing based on a file it will explore. |
---|
| 8 | ! globgrd_getgrid : This routine extracts the coordinates and land/sea mask from the domain files. |
---|
| 9 | ! globgrd_writevar : Writes a variables into a netCDF file which can then be analysed to verify that the |
---|
| 10 | ! forcing grid was well read and interpreted by this module. |
---|
| 11 | ! globgrd_writegrid : Write a grid description file which has the WRF flavor. It allows to exchange grid information |
---|
| 12 | ! between an atmospheric model (mostly a driver !) and ORCHIDEE which are coupled through OASIS. |
