Sounder SIPS: EOS-Aqua AIRS Level 3 Climate Fingerprinting Sounder Product (ClimFiSP) Monthly: Gridded Atmosphere, Cloud, and Surface Geophysical State V2

Published by NASA/GSFC/SED/ESD/TISL/GESDISC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 02:01 PM | Dataset Last Updated: June 23, 2026
The Climate Fingerprinting Sounder Product (ClimFiSP) Version 2 provides Level 3 daily and monthly atmospheric data including temperature profiles, water vapor, ozone, cloud properties, as well as surface properties, including skin temperature and emissivity. Data are available on a ½ by ½ degree grid. These geophysical variables are derived, via the ClimFiSP retrieval algorithm, from the Climate Hyperspectral Infrared Radiance Product (CHIRP), a Level 1 radiance product that harmonizes measurements from three different infrared sounding instruments: the AIRS sensor on EOS-Aqua and the CrIS sensors on the Suomi-NPP and NOAA-20 (JPSS-1) satellites. All three platforms follow similar sun-synchronous orbits, with CLIMFISP daily records including data for both the ascending (1:30 p.m.) and descending (1:30 a.m.) orbit passes. ClimFISP retrievals derived from each instrument are provided separately to facilitate detection of potential radiance biases between the CHIRP-AIRS and CHIRP-CrIS data records, and to evaluate their impact on the long-term data record formed by merging AIRS and CrIS data.
