---|
| 13 | !! Following subroutines are public and called from dim2_driver : |
---|
| 14 | !! - forcing_info : Open the forcing file and return information about the grid in the forcing file. |
---|
| 15 | !! Prepare for a zoom if needed. |
---|
| 16 | !! Initialization of parallelization related to the grid. |
---|
| 17 | !! - forcing_read : Return the forcing data for the current time step of the model. The forcing file will |
---|
| 18 | !! be read if it has not already been done for the current time-step in the forcing file. |
---|
| 19 | !! - forcing_grid : Calculate the longitudes and latitudes of the model grid. |
