IASI instrument: technical description and measured performances

摘要: IASI is an infrared atmospheric sounder. It will provide meteorologist and scientific community with spectra. The system includes 3 instruments that be mounted on the Metop satellite series, a data processing software integrated in EPS (EUMETSAT Polar System) ground segment technical expertise centre implemented CNES Toulouse. instrument composed of Fourier transform spectrometer associated imager. optical configuration based Michelson interferometer interferograms are processed by on-board digital subsystem, which performs inverse transforms radiometric calibration. imager co-registers soundings AVHRR (AVHRR another satellite). presentation focus architectures instrument, description technologies measured performance first flight model. leading program association EUMETSAT. Prime ALCATEL SPACE.
