Clear-sky emissivity after Idso & Jackson with a cloud correction; the
formulation used by AEME::calc_in_lwr() (originally gotmtools).
Usage
calc_in_lwr(cc, airt, relh = NULL, dewt = NULL)
Arguments
- cc
cloud cover fraction, 0-1.
- airt
air temperature, degC.
- relh
relative humidity, percent. Used to derive dewt when that
is not supplied.
- dewt
dew point temperature, degC. Takes precedence over relh.
Value
downwelling longwave irradiance, W m-2.
Examples
calc_in_lwr(cc = 0.4, airt = 15, relh = 70)
