Abstract

The radiometric calibration of the two optical sensors on the Earth Observing One satellite has been studied as a function of time since launch. The calibration has been determined by ground reference calibrations at well-characterized field sites, such as White Sands Missile Range and dry playas, and by reference to other sensors such as the Enhanced Thematic Mapper Plus (ETM+) on Landsat 7. The ground reference calibrations of the Advanced Land Imager (ALI) give results consistent with the on-board solar calibrator and show a significant shift since preflight calibration in the short wavelength bands. Similarly, the ground reference calibrations of Hyperion show a change since preflight calibration, however, for Hyperion the largest changes are in the short wave infrared region of the spectrum. Cross calibration of ALI with ETM+ is consistent with the ground reference calibrations in the visible and near infrared. Results showing the changes in radiometric calibration are presented.
