optical watt and the electrical watt ( Martin et al. 1985 ). The other is source based through the use of blackbodies with SI-traceable thermometry whose radiance can be described by the Planck function for blackbody radiation ( Fox 2000 ). Although national meteorology institutes have built their primary radiometric scales around the detector-based method, on spaceborne infrared sounders lower uncertainties may be achieved with source-based methods. A review of remote sensing calibration by National

Introduction The National Oceanic and Atmospheric Administration (NOAA) series of satellites carry instruments designed to measure atmospheric temperature and moisture. These instruments are the High-Resolution Infrared Radiation Sounder (HIRS), the Advanced Very High Resolution Radiometer, and the Microwave Sounding Unit (MSU). HIRS is the primary instrument for atmospheric sounding. It is well known that some of the 4.3- μ m HIRS channels are contaminated by solar radiation ( Wark 1993
