CrIS Level 1 - Multimission - Regional
Description
The Cross-track Infrared Sounder (CrIS), a Fourier transform spectrometer with 2211 spectral channels, produces high-resolution, three-dimensional temperature, pressure, and moisture profiles. These profiles are used to enhance weather forecasting models, and to facilitate both short- and long-term weather forecasting. Over longer timescales, they will help improve understanding of climate phenomena such as El Niño and La Niña. A subset of 431 spectral channels only are included in order to reduce data volume. EUMETSAT Advanced Retransmission Service (EARS) provides instrument data from the NOAA-20 and NOAA-21 satellites collected via a network of Direct Readout stations.
