! Modifications: |
| 19 |
! 21/06/01: Make integrations of more than one year possible ;-) |
| 20 |
! ATTENTION!! runs are supposed to start with Jan, 1. 1930 |
| 21 |
! (rday=1) |
| 22 |
|
| 23 |
! 27/06/01: Correction: The model always has 360 days per year! |
| 24 |
! 27/06/01: SO4 concentration rather than mixing ratio |
| 25 |
! 27/06/01: 10yr-mean-values to interpolate |
| 26 |
! 20/08/01: Correct the error through integer-values in interpolations |
| 27 |
! 21/08/01: Introduce flag to read in just one decade |
