17. GOFC/GOLD-FIRE Workshop on Global Geostationary Fire Monitoring Applications Slide: 17 Radiometric Correction - Principle Level 1.0 measured values (example: represents a constant radiance Counts (10 bit) Time sensor degradation gain change Level 1.5 count - constant! “count” : satellite measurement for a given pixel (10 bit) radiance = cal_slope * count - cal_offset

18. GOFC/GOLD-FIRE Workshop on Global Geostationary Fire Monitoring Applications Slide: 18 Radiometric Correction / Calibration (Thermal Channels) Rescaling of raw counts (to account for gain changes) Conversion to radiances (applying ground measurements) Equalisation of 3 sensors Application of blackbody information Scale to 10 bit integers Apply cal_slope and cal_offset scaling cal_offset and cal_slope are initially only scaling parameters for the Level 1.5 data ==> ideally, these are also the calibration constants

19. GOFC/GOLD-FIRE Workshop on Global Geostationary Fire Monitoring Applications Slide: 19 The actual “validity” of cal_slope and cal_offset in terms of true calibration data is ensured by the MPEF product “Calibration Monitoring”: Vicarious calibration using targets of know radiative properties and radiation models Intersatellite calibration (e.g. with polar orbiters) In case of large disagreement: the MPEF calibration coefficients will be inserted into the Level 1.5 image header Radiometric Correction / Calibration (Thermal Channels)
