Geostationary Interferometric Infrared Sounder (GIIRS)
An infrared hyper-spectral vertical sounder, also the first space-borne interferometer that flies in geostationary orbit to take measurements of three dimensional atmospheric structure from interference of split light beams. Technically featured by a 32×4 sensor array plane, a Michelson interferometer working over different infrared bands for large-area, continuous, fast, and accurate vertical air soundings of temperature and humidity.
The soruce for GIIRS data is reprocessed from University of Wisconsin Space Science Engineering Center (SSEC) on the S4 Supercomputer
For each variable and/or satellite channel, shown are the observation counts (left), O-B RMSD (center), and O-B bias (right).
