C !DESCRIPTION: |
| 16 |
C Calls the implicit vertical advection/diffusion routine |
| 17 |
C for each passive tracer. |
| 18 |
C And apply open boundary conditions for each passive tracer |
| 19 |
C Note: would be better to apply OBC in a dedicated S/R ; |
| 20 |
C can be done here assuming no other contribution modify passive |
| 21 |
C tracer after implicit vertical diffus/advect is applied. |
