CZ 09D 12B AV0Z1075907 The ETM+ internal calibrator signal is analyzed, in several spectral bands, and modeled functionally using several instrument-state quantities available in the Landsat-7 telemetry. Models were tested and compared in terms of their complexity, explanatory power and fit. The intent of such models is to provide a way to correct for the internal calibrator instabilities and allow for more precise usage of calibrating ETM+ data on-orbit. Some of proposed computer models can be accessed interactively on the WWW. cav_un_auth*0212856 Europto Remote Sensing Conference 2000 Barcelona ES 25.09.2000-29.09.2000 BB SI http://hdl.handle.net/11104/0130811 UTIA-B 20010192 2001 2001 Bellingham SPIE 0-8194-3825-1 Sensors, Systems, and Next-Generation Satellites IV .
