c |
| 12 |
c o Map external forcing fields (ustress, vstress, hflux, sflux, |
| 13 |
c swflux, apressure, climsss, climsst, etc.) onto ocean model |
| 14 |
c arrays (fu, fv, Qnet, EmPmR, Qsw, pload, sss, sst, etc.). |
| 15 |
c This routine is included to separate the ocean state estimation |
| 16 |
c tool as much as possible from the ocean model. Unit and sign |
| 17 |
c conventions can be customized using variables exf_outscal_*, |
| 18 |
c which are set in exf_readparms.F. See the header files |
| 19 |
c EXF_FIELDS.h and FFIELDS.h for definitions of the various input |
| 20 |
c and output fields and for default unit and sign convetions. |
