Abstract

The primary objective of this project was to establish a cross-calibration connection from the Landsat-5 MSS back to the Landsat-I MSS in order to consistently calibrate the entire MSS data in the USGS archive. First, the lifetime radiometric stability of all five MSS sensors was studied using the Sonoran desert invariant site. The responses of these sensors, in terms of TOA reflectance values, were compared to determine the inconsistencies in their calibration. Next, a consistent cross-calibration of all MSS sensors was achieved using coincident/near-coincident scene pairs acquired during spatial and temporal overlap of these sensors. The effectiveness of these crosscalibration results was addressed by showing a significant improvement in the observed inconsistencies in the absolute calibration of five MSS sensors. Further, the Landsat-5 MSS was cross-calibrated to the Landsat-5 TM using simultaneous scene acquisitions from Libya-4. The mismatching spectral filter responses of MSS and TM were addressed by deriving the spectral band adjustment factors prior to the cross-calibration. Finally, a set of gain adjustment factors was recommended to improve the absolute calibration of MSS sensors in all four bands.
