NREL Long Wave Test



This is special test of long wave (infra red) irradiance developed by NREL for the ARM Program. Required fields are as follows:

Upwelling Long Wave Irradiance (LWup)TF1
Downwelling Long Wave Irradiance (LWdn)TF2
Direct Normal Irradiance (DNI)CF1
Global Horizontal Irradiance (GHI)CF2
Diffuse Horizontal Irradiance (DHI)CF3
DNI Flag (from SERI_QC Test)CF1F
GHI Flag (from SERI_QC Test)CF2F
DHI Flag (from SERI_QC Test)CF3F
Minimum LWupF1
Maximum LWupF2
Minimum LWdnF3
Maximum LWdnF4
