Abstract

At the eve of the launch of the MetOp satellite (nominally from 30 June 2006), a status is given concerning the Infrared Atmospheric Sounding Interferometer (IASI), which will be, as a second generation IR operational sounder, one of the key instrument of the first European polar orbit satellite for operational meteorology, with very promising capabilities for Earth sciences including atmospheric composition and climate. The operational and science objectives of IASI will be briefly reviewed together with an overview of the overall IASI programme run in common by Eumetsat and CNES. The performances of the first model to be flown have been extensively assessed during the qualification process performed by the prime contractor (Alcatel Space Alenia) under the overall responsibility of CNES. Results demonstrating the spectral and radiometric performances will be presented. IASI products (level 1 and 2) will be reviewed together with their expected precision and space/time coverage. The role of the Technical Expertise Centre (TEC) for optimizing and controlling the instrument parameters once in orbit together with the calibration/validation plan will be discussed.
