Over the last years, more and more satellite data on tropospheric composition have become available and are now being used in numerous applications. In this session, we aim to bring together reports on new or improved data products and their validation, as well as studies using satellite data for applications in tropospheric chemistry, emission inversions and air quality. This includes both studies on trace gases and aerosols.

We welcome presentations based on studies analysing data from current and future satellite missions, including the geostationary GEMS, TEMPO and Sentinel-4 platforms and the recent S5, IRS, IASI-NG and 3MI instruments.
Topics also include the inter-comparisons of different remote sensing measurements dedicated to tropospheric chemistry sounding and/or analyses with ground-based measurements and chemical transport models.
