This paper summarizes the satellite and aircraft radiometric calibration and atmospheric correction work carried out as part of the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) by members of the staff science group at NASA Goddard Space Flight Center (GSFC). As part of FIFE a large volume (120 gigabytes) of radiometric data were acquired and derived from a number of different instruments on a variety of platforms. The Same basic procedure was applied to each instrument, that is: derive the most recent calibration coefficients for converting sensor counts to reflective spectral radiances; correct the radiances for earth-sun distance variations and incident solar spectral irradiance within the bandpass of each respective instrument channel at the top of the atmosphere; characterize the atmosphere for aerosols and absorbing gases; and derive apparent surface reflectance by correcting the exoatmospheric values for atmospheric attenuation. The same basic approach was used for surface temperature derivation. The results of this processing were then verified by surface measurements, corroborated by sensor intercomparisons, and made available to investigators for their respective applications. The FIFE calibration and atmospheric correction summarized here exemplifies the level of effort required to make useful radiometric data available at a variety of scales for science applications.
