| Summary: | Abstract. A technique for evaluating the radiometric calibration of satellite-born radiometers has been developed utilizing the stable reflectance of the Antarctic land mass. Previously, the scene radiances measured over the Antarctic and Greenland land masses were used to monitor time evolution of sensor radiometric sensitivity and to compare instruments with similar spectral responses. Through the use of radiative transfer modeling, we can now evaluate the albedo calibration (Earth radiance sensitivity divided by solar irradiance sensitivity) of any nadir-viewing, polar orbiting sensor measuring in the 300-800 nm range. Our evaluation of the Ozone Monitoring Instrument on the NASA Aura spacecraft confirms a 2 % calibration uncertainty. |
