The Cross-track Infrared Sounder (CrIS), a Fourier transform spectrometer with 1305 spectral channels, will produce high-resolution, three-dimensional temperature, pressure, and moisture profiles. These profiles will be used to enhance weather forecasting models, and they will 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. Get more information about the CrIS instrument.
