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.
