C | SUBROUTINE CALC_WSURF_TR |
| 14 |
C | o Compute a correction for the source/sink of tracer |
| 15 |
C | due to the linear free surface. |
| 16 |
C | o The source/sink results from W*Tr not summing to |
| 17 |
C | zero at the free surface. |
| 18 |
C | o Here, we compute an area-weighted mean correction |
| 19 |
C | to be applied in external_forcing.F |
