Data Description

    Infrared Atmospheric Sounding Interferometer Granule Data - 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. This data family provides IASI Level-1C data from EUMETSAT and IASI Level-2 NOAA Unique Products (NUPS) from NESDIS. The level 1C data is geo-located, calibrated and apodized. The NOAA Unique products include Cloud-Cleared Radiances (CCR), Outgoing Longwave Radiation (OLR), and an Environmental Data Record with ozone, temperature, moisture and trace gas profiles. These products are provided by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) in the netCDF-4 file format with attributes included.
