The IASI family of instruments has been sounding the atmosphere since 2006 onboard the Metop satellite series. Using the radiance data recorded in the thermal infrared spectral range, concentrations for atmospheric pollutants such as carbon monoxide (CO), ozone (O3), sulfur dioxide (SO2) and ammonia (NH3) can be derived. Moreover, meteorological fields, such as temperature and humidity can be used for weather forecast and climate trends analysis. IASI CO and O3 fields are currently assimilated in regional and global models in order to predict air quality over Europe; SO2 alerts are delivered when exceptional levels are encountered, and NH3 source hotspots are tracked throughout the globe.
