C NOTES: |

C ====== |
| 129 |
c |
| 130 |
C All surface forcing fields are defined at the center of |
| 131 |
C each grid (the rVel location in model/inc/GRID.h) with |
| 132 |
C one exception. When both ALLOW_BULKFORMULAE and |
| 133 |
C USE_EXF_INTERPOLATION are undefined, ustress and vstress are |
| 134 |
C defined at the Southwest C-grid U and V points, respectively. |
| 135 |
c |
| 136 |
C Input and output units and sign conventions can be customized |
| 137 |
C using variables exf_inscal_* and exf_outscal_*, which are set |
| 138 |
C by exf_readparms.F |
| 139 |
c |
| 140 |
C Output fields fu, fv, Qnet, Qsw, and EmPmR are |
| 141 |
C defined in FFIELDS.h |
| 142 |
c |
| 143 |
C #ifndef SHORTWAVE_HEATING, hflux includes shortwave, |
| 144 |
C that is, hflux = latent + sensible + lwflux +swflux |
| 145 |
