The Infrared Atmospheric Sounding Interferometer is a Cross-nadir infrared sounder flown on the European MetOp satellite series. IASI measures atmospheric emission spectra to derive temperature and humidity profiles with high vertical resolution and accuracy. IASI is a Michelson interferometer with spectral coverage between 3.6 and 15.5 micrometers. At nadir, the instrument samples data at intervals of 25 km along track and cross track with each sample having a maximum diameter of about 12 km. The IASI Level-2 Environmental Data Record (EDR) from MetOp-B/C is a NOAA-unique product generated from the European Organization for Meteorological Satellites (EUMETSAT) IASI level 1C data. This product provides ozone, temperature, moisture and trace gas profiles. The data are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) as 3 minute files in the netCDF-4 file format with attributes included.
