Infrared Atmospheric Sounding Interferometer (IASI) Level 1C Data

Infrared Atmospheric Sounding Interferometer (IASI), is a hyperspectral infrared sounder residing on the European Space Agency's (ESA) MetOp series of polar orbiting satellites. 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. The level 1C data are ingested in a pipeline mode from EUMETSAT and then applied to spectral and spatial sub-setting. Datatypes available are Level 1C granules from EUMETSAT.
