This paper presents the infrared atmospheric sounding interferometer (IASI) being developed at CNES Toulouse. IASI is a part of the operational meteorological payload managed by EUMETSAT. The baseline platform for the first flight model of the instrument is the METOP-1 polar platform to be launched during 2000/2001. IASI consists of a Fourier transform spectrometer (FTS) based on a Michelson interferometer coupled to an integrated imaging system which allows characterization of cloudiness inside the FTS field of view. This instrument will provide spectra of high radiometric quality at 0.5 cm-1 resolution from 15.5 micrometers to 3.4 micrometers , with global coverage twice per day at 25 km horizontal resolution.
