Since early 2012, the cross-track infrared sounder (CrIS) onboard the Suomi National Polar-Orbiting Partnership satellite has continually provided the hyperspectral infrared observations for profiling atmospheric temperature, moisture, and greenhouse gases. The CrIS radiance data are also directly assimilated into global numerical weather prediction models to improve the medium-range forecasts. These...
Given the fact that Cross-track Infrared Sounder (CrIS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) currently are onboard the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite and will continue to be carried on the same platform of future Joint Polar Satellite System (JPSS) satellites for the next decade, it is desirable to develop a fast and accurate collocation scheme...
The Cross-track Infrared Sounder (CrIS) on Suomi National Polar-orbiting Partnership Satellite (S-NPP) is a Fourier transform spectrometer and provides a total of 1305 and 2211 channels in normal spectral resolution (NSR) mode and full spectral resolution (FSR) mode, respectively, for sounding the atmosphere. NOAA operated CrIS in FSR mode on December 4, 2014 for S-NPP, and will operate CrIS in FSR...
Calibration and validation of sensors is important for understanding how a sensor operates during its mission and shows the level of measurements that can be expected. The calibration is an on-going process throughout the mission but is most critical when the complete system comes together and during its initial stage after reaching orbit. Careful planning is required to accurately and efficiently...
Brightness temperatures from NOAA-18 and NOAA-19 MHS measurements are investigated over Antarctica to establish it as a natural vicarious calibration target for determination of the Inter-satellite/inter-sensor Calibration Biases (ICB) of the two MHS radiometers. Establishment of a natural test site for calibration references is important for calibration and validation of space-borne microwave instruments
