JPSS-1 CrIS Level 1B Principal Component Analysis / Rapid Event Detection V3.0 (SNDRJ1CrISL1BPCARED) at GES DISC

This sample data collection contains L1B radiance values that are compressed and denoised via Principal Component Analysis (PCA). Additionally it contains a new Rapid Event Detection (RED) product, which for multiple spectral regions identify where rare signals are observed, providing an efficient and useful way to locate and study interesting phenomena. Some of the potential uses for these RED components are the detection of atmospheric gases where fires and volcanoes occur. PCA/RED might be a desirable alternative to the existing L1B product because (1) it is many times smaller in data volume, (2) about 80% of the random noise is removed, and (3) it comes with the new RED component.

The Cross-track Infrared Sounder (CrIS) Level 1B Full Spectral Resolution (FSR) data files contain radiance measurements along with ancillary spacecraft, instrument, and geolocation data of the CrIS instrument on the Joint Polar Satellite System-1 (JPSS-1) platform. This platform is also know as NOAA-20 (National Oceanic and Atmospheric Administration).
