Paper Abstract

This work demonstrates how lunar data are used by three different imaging radiometers: the Visible and InfraRed Scanner (VIRS) onboard the Tropical Rainfall Measuring Mission (TRMM) and the MODerate resolution Imaging Spectroradiometers (MODIS) onboard the EOS Terra and Aqua satellites. Using the measured lunar data, radiometric models have been developed for the on-orbit calibration of the remote sensing systems' reflected solar bands. For the VIRS with spectral bands nearly identical to several of the MODIS bands, the integrated lunar reflectance data were measured, from Jan 1998 to Jun 2006, at phase angles ranging from 1.2° to 120.2°. For the two nearly identical MODIS instruments, the lunar irradiance was measured at phase angles from 54° to 56°. We present stability trending of the lunar data at selected phase angles over periods of four to eight years and use these observations to examine instrument radiometric stability. Moreover, we discuss implications of these results.
