- Abstract
The Infrared Atmospheric Sounding Interferometer (IASI) on-board METOP, took off from Baïkonour in October 20006. This key element of the European Meteorological polar-orbit satellites, resulting from a close cooperation between EUMETSAT and CNES, will offer highly accurate data about the atmosphere, land and oceans for application to weather predictions and climate studies. The IASI instrument consists of a Fourier transform Spectrometer operating in the 3.7-15.5µm spectral range for determination of the temperature (accuracy of 1K and a vertical resolution of 1Km) and humidity profile (accuracy of 10The early in-orbit activities were dedicated to the instrument characterizations in order to demonstrate that the instrument was not altered by the launch and in-orbit environment. The calibration and validation program will deeply analyze the instrument performances leading to the dissemination of the products to the users community. This paper provides a brief presentation of the IASI Mission and a presentation of the instrument architecture. The instrument characterization established during the commissioning phase and the preliminary performances will be detailed.
