Validation of geostationary operational environmental satellite-16 advanced baseline imager radiometric calibration with airborne field campaign data and reanalysis of north-south scan data

The advanced baseline imager (ABI) on board geostationary operational environmental satellite-16 (GOES-16) provides high quality reflective solar band (RSB) and thermal emission (TEB) image data. Intensive field campaigns for postlaunch validation of the ABI Level-1B spectral radiance observations were carried out during March to May 2017 ensure Système International traceability ABI. Radiometric calibrations RSBs TEBs evaluated by comparison with measurements airborne visible infrared imaging spectrometer-next generation (AVIRIS-NG) scanning high-resolution interferometer sounder (S-HIS) high-altitude aircraft ER2, respectively. between RSB mesoscale (MESO) data AVIRIS-NG showed that mean biases are within 2% uncertainty <2.5 % CH01, CH03, CH05, CH06. brightness temperature differences GOES-16 S-HIS shown be 0.45 K <0.35 at 300 scene equivalent CH08 CH10 CH13 CH15. uses large focal plane arrays detector number varying from hundreds more than a thousand per channel, which makes evaluation uniformity challenge. Reanalysis north-south scan campaign lunar observation was performed CH01 CH03 two versions calibration coefficients. Significant improvements in updated algorithm verified.
