EOS Calibration Program

Level 1B validation or vicarious calibration campaigns involve ground-based, airborne, and on-orbit satellite sensors making simultaneos radiometric measurements of spatially and spectrally homogeneous Earth targets for purposes of validating the on-orbit satellite radiometric calibration. These campaigns provide an effective check of the operation and reliability of the satellite on-board calibration systems. The campaigns also enable the comparison and validation of the on-orbit calibration of follow-on sensors employing different optical designs and on-board calibration systems.

Personnel within the EOS Calibration Program and NIST participate in laboratory-based measurement comparisons of vicarious calibration instruments involving multiple investigator groups. In addition, the EOS Calibration Program and NIST have plan to formulate sets of calibration/characterization and measurement protocols for common vicarious calibration instruments.
