C   FORCING FIELD VARIABLES
C- Mandatory:
C  tair      :: air temperature (K)
C  qair      :: specific humidity at surface (kg/kg)
C  rain      :: total precipitation (= rain + snow) (m/s), (>0: rain)
C  solar     :: downward shortwave radiation (W/m^2), (>0: downward)
C  flwdwn    :: downward longwave radiation  (W/m^2), (>0: downward)
C  wspeed    :: wind speed (m/s)
C- Optional:
C  uwind     :: zonal wind speed (m/s),      at cell center (A-grid)
C  vwind     :: meridional wind speed (m/s), at cell center (A-grid)
C  runoff    :: freshwater runoff (m/s)
C  Qnetch    :: net heat flux (cheating)
C  EmPch     :: E-P (cheating)
C  cloud     :: fraction sky covered in cloud
C  thAir     :: Air potential temp. in the BL [K]
C                (used in AIM-formula stability function)
