Infrared Thermometer (IRT): upwelling radiance, instantaneous 20-sec at 25-meter height (irt25m20s)

Browse Data

The infrared thermometer (IRT) is a ground-based radiation pyrometer that measures the equivalent blackbody brightness temperature of the scene in its field of view. The downwelling version has a narrow field of view for measuring sky temperature and detecting clouds. The upwelling version has a wide field of view for measuring the narrowband radiating temperature of the ground surface.
