IASI Infrared Interferometer for Operations and Research

The paper presents the high-resolution infrared interferometer being developed, in cooperation between France and Italy, to meet the needs of meteorology and atmospheric sciences in temperature, humidity profiles, and to provide limited information on trace gas abundance’s. The instrument is planned for launch as part of the meteorological payload onboard the European Polar Platform POEM-1. Presently in phase B, this Fourier transform spectrometer will provide spectra of high radiometric quality at 0.25 cm-1 resolution from 15.5 to 3.4 micrometers, with global coverage twice per day at 25 km horizontal resolution.
