Estimates upward facing ground radiation (W/m2), from the Stephan Boltzmann relationship and ground temperature
Lu(Tg = 20, Eground = 0.97)
Ground temperature (degrees celsius)
Emissivity of soil or ground. Default value is 0.97.
Calculates ground radiation facing upward. Assumes ground emissivity = 0.97. Terrain emissivities vary from 0.89 (sand, snow) to 0.97 (moist soil) - Blaxter, 1986
A value, vector of length one, corresponding to the longwave radiation from the ground, units: W/m2.
