|
C o Map external forcing fields (ustress, vstress, hflux, sflux, |
| 18 |
|

C swflux, apressure, climsss, climsst, etc.) onto ocean model |
| 19 |
|
|
C arrays (fu, fv, Qnet, EmPmR, Qsw, pLoad, SSS, SST, etc.). |
| 20 |
|
|
C This routine is included to separate the ocean state estimation |
| 21 |
|
|
C tool as much as possible from the ocean model. Unit and sign |
| 22 |
|
|
C conventions can be customized using variables exf_outscal_*, |
