c |
| 12 |
c o Map the external forcing fields on the ocean model arrays. This |
| 13 |
c routine is included to separate the ocean state estimation tool |
| 14 |
c as much as possible from the ocean model. Unit conversion factors |
| 15 |
c are to be set by the user. |
| 16 |
c |
| 17 |
c The units have to be such that the individual forcing record has |
| 18 |
c units equal to [quantity/s]. See the header file *FFIELDS.h* of |
| 19 |
c the MITgcmuv. |
| 20 |
c |
| 21 |
c Required units such that no scaling has to be applied: |
| 22 |
c |
| 23 |
c heat flux: input file W/m^2 |
| 24 |
c salt flux: input file m/s |
| 25 |
c zonal wind stress: input file N/m^2 |
| 26 |
c merid. wind stress: input file N/m^2 |
| 27 |
c |
| 28 |
c To allow for such unit conversions this routine contains scaling |
| 29 |
c factors scal_quantity. |

c Patrick Heimbach, heimbach@mit.edu 06-May-2000 |
| 43 |
c |

| 46 |
c |
| 47 |
c Patrick Heimbach, heimbach@mit.edu 23-May-2000 |
