Atmospheric temperature profiles deduced from radiation measured from orbiting satellites often disagree systematically with in situ soundings by radiosondes. From comparisons between satellite and radiosonde soundings we derive empirical adjustments to the values of radiance measured at the satellite. In a test with real data the adjustments improved the agreement between satellite soundings and radiosondes. This test also showed that radiance adjustments were more effective than transmittance adjustments.
