Medium background infrared radiometry deals with the radiometric measurements in approximately 80 K environment. NIST-traceable calibrations in an 80 K environment are important for many space-based applications. The 80 K environment produces thermal radiation, but this is negligible for the purposes of programs involving blackbody sources with temperatures between 250 K and 350 K. One of the initial calibrations was for the thermal transfer radiometer (TXR) developed at the NIST in support of the Earth Observing System (EOS). The EOS is the key element in the Mission to Planet Earth (MTPE) program of the National Aeronautics and Space Administration (NASA).
