In this article, we describe a method for the calibration of thermopile pyrgeometers in the absence of a reference for measurement of atmospheric longwave irradiance. This is referred to as the incoming longwave irradiance in this article. The method

Thermopile pyranometers’ thermal offset has been recognized since the pyranometer’s inception. This offset is often overlooked or ignored because its magnitude is small compared to the overall solar signal at higher irradiance. With the demand of

Uncertainty in terrestrial solar radiation measurements of a few watts per square metre (1 W/m2 to 2 W/m2) is needed to validate estimates of the Earth's radiation balance derived from satellite data. The characterization of solar energy resources fo
