Data Description

    Infrared Atmospheric Sounding Interferometer Granule Data - The Infrared Atmospheric Sounding Interferometer is flown on METOP-A. The main goal is to provide atmospheric emission spectra to derive temperature and humidity profiles with high vertical resolution and accuracy. It 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 and a cross track, each sample having a maximum diameter of about 12 km. The level 1C data is geo-located, calibrated and apodized. Datatypes available are Level 1C granules from EUMETSAT, Level 2 and CCR profiles from NOAA.
