NREL UPWelling Short Wave Test


This is special test of upwelling short wave irradiance developed by NREL for the ARM Program. Required fields are as follows:

Upwelling Short Wave Irradiance (SWup)TF1
Downwelling Short Wave Irradiance (SWdn)TF2
Solar zenith angleZenith
SWup / extra-terrestrial irradiance on a horizontal surface (ETR)KU
Normally expected value of: SWdn / ETRKtmax
SWup / SWdnAlbedo


Test Flags are set as follows:
