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. IASI CO and O₃ fields are assimilated in regional and global models in order to predict air quality over Europe. Enhanced levels of pollutants are detected in near-real time, and can be followed at city, country and continent levels. This talk will present the findings for an extended time period (2008-2017), and will review the IASI capability to observe exceptional events both at the local and regional scales, as well as seasonal variations due other dynamic patterns (monsoon, ENSO, …). Progresses and current limitations to derive long term trends will also be discussed.
