This work is part of the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE), an international land-surface-atmosphere experiment aimed at improving the way climate models represent energy, water, heat, and carbon exchanges, and improving the utilization of satellite based remote sensing to monitor such parameters. This paper reports on the work of the atmospheric corrections and radiometric calibration subgroup of FIFE. The responsibility of this group included calibration of remote sensing instrumentation used on surface platforms and aircraft, establishing recommendations for calibrating satellite observations, measurement of relevant atmospheric properties, development of algorithms which will perform the atmospheric corrections for the remotely sensed data, and finally evaluation of surface properties, including reflectances and temperatures. Good progress was made for cloudless and low-haze atmospheric conditions, but no effort was directed toward more complicated conditions, since little FIFE data was collected in these conditions. Studies of aircraft mounted instrumentation revealed that some of this instrumentation was not adequately designed for radiometric calibration, and thus the errors are very large for some of this data.
