Experiment demonstrates feasibility of using recently calibrated airborne radiometer to calibrate satellite-borne radiometer monitoring Earth and not calibrated since before launch. Calibration technique helps to assure Earth scientists of accuracy of satellite radiometric measurements taken during long time. Optical train of orbiting radiometer degraded slowly and sensitivities of detectors and gains of amplifiers changed slowly in outer-space environment, but frequent calibrations by airborne-radiometer technique make it possible to compensate for these changes.
