Calibration Coefficients METEOSAT-3
METEOSAT-3: Normalized coefficients for VIS scaled radiances (0 to 1) and IR brightness temperatures in Kelvins. METEOSAT-3 operated as a replacement for GOES-EAST from August 1991. The Normalized coefficients result from
comparison to the reference AVHRR for that time period.
