Intercalibration at CIMSS

Intercalibrating of Geostartionary and Polar Orbiting Instruments

We don't make the satellite products you use.

Intercalibration of the polar orbiting and geostationary satellite systems is necessary to achieve consistency of data sets involving more than one sensor. The community of satellite operators needs to intercalibrate their current sensors to reduce the calibration uncertainty and maximize calibration uniformity. This web page presents the approach developed at the Cooperative Institute for Meteorological Satellite Studies (CIMSS) for calibrating the geostationary satellites with a polar orbiting satellite using temporally and spatially collocated measurements in the infrared channels.

Data is being collected and processed on a daily basis. This web page is normally updated daily with new results.
