In the context of the EO Science for Society Programme Element, the European Space Agency has organised ATMOS-2021, a conference on the topical theme Atmosphere aimed at exploiting data from ESA and EO Missions for science and application development.

The purpose of the conference was to provide scientists and data users with the opportunity to present first-hand and up-to-date results from their ongoing research and application development activities by using data from past and current atmospheric instruments like Copernicus Sentinel-5p, Aeolus, ERS-2, Envisat, Metop, and ESA Third Party Missions. Another aspect was to discuss results from using data from Copernicus Services such as CAMS and C3S, models and data assimilation, as well as data from ground-based and airborne sensors. Finally, the conference also provided a platform to discuss activities regarding future missions, e.g. Copernicus Sentinel-4, Copernicus Sentinel-5, CO2M, FORUM, EarthCARE, Altius as well as ESA Earth Explorer 11 candidates.

The outcome of this conference is used to further shape the next generation of R&D activities in the frame of the ESA Earth Observation Programme.
