Infrared Thermometer (IRT)
Instrument Categories: Radiometric, Surface/Subsurface Properties
General Overview
The Infrared Thermometer (IRT) is a ground-based radiation pyrometer that provides measurements of 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 for detecting clouds. The upwelling version has a wide field of view for measuring the narrowband radiating temperature of the ground surface.
Primary Measurements Taken
The following measurements are those considered scientifically relevant. Refer to the netCDF File Header Descriptions (Data Object Design Files) for the list of all available measurements, including those recorded for diagnostic or quality assurance purposes.
