subroutine fizhi_init_fixed (myThid) |
| 6 |
c----------------------------------------------------------------------- |
| 7 |
c Routine to initialise the fizhi package. |

c Input: myThid - Process number calling this routine |
| 10 |
c |
| 11 |
c Notes: |
| 12 |
c 1) This routine is the interface to read input datasets and set |
| 13 |
c other fixed variables for fizhi |
| 14 |
c the datasets are: |
| 15 |
c vegetation (data for each tile at every grid point) |
| 16 |
c ozone (varies with lat, height and time - read it all in |
| 17 |
c now and interpolate between values later) |
| 18 |
c the other fixed parameters are: |
| 19 |
c N2O, Methane (vary with space) |
| 20 |
c CO2, CFC11, CFC12, CFC22 (set to a global value) |
| 21 |
c 3) For now, the fizhi package contains the alarms and clocks |
| 22 |
c routines, so this routine will also initialize the alarms. |
