Paper Abstract

Earth-observing satellite sensors are calibrated in the laboratory against blackbody and lamp-based uniform optical radiation standards. These sources and additional characterization tests fail to approximate the spatially, spectrally, and temporally complex scenes viewed on-orbit by these sensors. The lack of appropriate diagnostic tools limits the ability of researchers to fully characterize and understand the radiometric performance of sensors before deployment. The consequences of these limitations are that problems in a sensor's performance, e.g. optical crosstalk, scattered light, earth-shine, are often first observed on-orbit. Advanced radiometric characterization artifacts, able to produce realistic spectral distributions and spatial scenes in the laboratory, would enable more complete instrument characterization, with the resulting potential benefit of improved on-orbit performance.
