GSICS Baseline Satellite Instrument Inter-Calibration Analyses
Efforts to ensure the quality of products developed within GSICS have led, whenever possible, to the development of GSICS product verification tools. One family of verification tools is satellite inter-calibration baseline algorithms. These algorithms capture the fundamental physical concepts of similar, but more comprehensive, GSICS product satellite inter-calibration algorithms. In addition, the baseline algorithms have the capability to be applied to all instruments within a given instrument class. Therefore, the results of the more basic baseline algorithm can be compared with algorithms that have more complexity. Any discrepancies can be used as a platform from which to search for errors in the more complex product algorithms, and/or significant inadequacies of the baseline algorithm. Thus, the analyses that result from simultaneously runnning baseline and GSICS product algorithms become a cross-check, and a workbench, by which the discipline of inter-satellite calibration can evolve.
