c ====== |
| 112 |
c |
| 113 |
c All surface forcing fields are defined at the center of |
| 114 |
c each grid (the rVel location in model/inc/GRID.h) with |
| 115 |
c one exception. When both ALLOW_BULKFORMULAE and |
| 116 |
c USE_EXF_INTERPOLATION are undefined, ustress and vstress are |
| 117 |
c defined at the Southwest C-grid U and V points, respectively. |
| 118 |
c |
| 119 |
c Input and output units and sign conventions can be customized |
| 120 |
c using variables exf_inscal_* and exf_outscal_*, which are set |
| 121 |
c by exf_readparms.F |
| 122 |
c |
| 123 |
c Output fields fu, fv, Qnet, Qsw, and EmPmR are |
| 124 |
c defined in FFIELDS.h |
| 125 |

| 126 |
c #ifndef SHORTWAVE_HEATING, hflux includes shortwave, |
