| 2 | ! MODULE forcing_tools : This module concentrates on the temporal interpolation of the forcing for ORCHIDEE. |
---|
| 3 | ! It provides basic service for the grid when this is provided in the forcing file. The main |
---|
| 4 | ! work for the grid is done in glogrid.f90. The approach of forcing_tools to handle the time |
---|
| 5 | ! aspect of the forcing is to read as many time steps as possible in memory and then |
---|
| 6 | ! interpolate that to the time interval requested by the calling program. |
---|
| 7 | ! The data is read on root_proc but then distributed over all processors according to the |
---|
| 8 | ! domain decomposition of ORCHIDEE. This allows to be more efficient in the temporal interpolation. |
---|
| 9 | ! It is important to keep in mind that forcing_tools works on time intervals. So the request for data |
---|
| 10 | ! of ORCHIDEE as to be for an interval and the forcing file needs to have a description of the time interval |
---|
| 11 | ! over which the forcing is valid. |
---|
| 12 | ! The general description of how the attributes needed in the netCDF file for describing the cell_methods |
---|
| 13 | ! for time are provided in this document : |

| 18 | ! forcing_integration_time : Computes the interval over which the simulation should be carried out. |
---|
| 19 | ! forcing_open : Opens the forcing files and extract the main information. |
