Abstract : Thermal infrared nadir-looking sounders on-board polar-orbiting satellites are now playing a key role for monitoring the atmospheric composition change. They add to the products available from UV-visible instruments and these altogether contribute in drawing a more complete picture of the tropospheric composition, its changes over space and time, and its impact on the global environment. The French IASI instrument launched onboard the European MetOp satellite series is providing essential inputs for weather forecasting and pollution/climate monitoring. This mission is recording atmospheric spectra at each location two times per day, with an excellent horizontal resolution and coverage, from which global, regional and local distributions of trace gas concentrations can be derived. Thanks to the very good radiometric performance of the instrument a list of 24 climate and chemistry relevant species has been identified. The talk will summarize operational near real time applications that are currently being developed, and illustrate the latest results obtain to track pollution plumes coming from different sources in order to monitor and forecast atmospheric composition.
