InLongRad

Value

Meaning

Konzelmann et al equation

The incoming longwave radiation is estimated with the atmospheric emissivity as a function of air temperature, vapour pressure and cloudiness as suggested by Konzelmann et al 1994 (in a study of the radiation balance over the Greenland ice-sheet) See Eq. (4.81).

Satterlunds equation

The incoming longwave radiation is estimated with the atmospheric emissivity as a function of air temperature, vapour pressure as suggested by Satterlund for clear-sky irradiance, complemented with a standard formulation of the influence of clouds. See Eq (4.83).

Brunts equation

The incoming longwave radiation is estimated with the formula by Brunt for clear-sky irradiance, complemented with a standard formulation of the influence of clouds. See Eq (4.82).
