|
C and latent heat flux due to evaporation (variable EVAP in |

|
C COMMON/FLUXES/, com_physvar.h). Index 2 of SHF and EVAP give fluxes |
| 55 |
|
|
C over sea. SLR is the flux that is radiated by the ocean/land. SSR |
| 56 |
|
|
C is the incoming short-wave radiation that is absorbed by the ocean/land. |
| 57 |
|
|
C Variable ALHC is the latent heat of evaporation/condensation (see |
| 58 |
|
|
C COMMON/PHYCON/, com_phycon.h). |
| 59 |
|
|
C HeatFlux is defined with positive into the atmosphere, units are W/m^2 |
