Short summary
We present a new upwelling longwave (LW) measurement technique that eliminates obstruction influences on pyrgeometers by using an infrared thermometer, downwelling LW pyrgeometer, and air temperature probe. This approach can be implemented at locations with obstruction challenges and verify existing upwelling LW pyrgeometer measurements. Satellite projects like the Clouds and the Earth's Radiant Energy System depend on accurate surface measurements to validate their models.
