Starting 2020, the PEEX special session on “Observation, Modelling and Assessment in the Arctic-Boreal Domain” is annually organized at the European Geosciences Union (EGU) General Assembly. In 2022, the EGU (https://www.egu22.eu) to be held during 3-8 April in Vienna, Austria.

The session is linked to the Pan-Eurasian EXperiment (PEEX; www.atm.helsinki.fi/peex), a multi-disciplinary, -scale and -component climate change, air quality, environment and research infrastructure and capacity building programme. It is co-organized with the Digital Belt and Road (DBAR) Programme.

The session is aimed at resolving major uncertainties in Earth system science and global sustainability issues concerning the Arctic, Northern Eurasia and China regions. This session aims to bring together researchers interested in: (*) determining relevant environmental, climatic, and other processes in Arctic-boreal regions (process understanding); (*) further development of the long-term, continuous and comprehensive ground-based, air/seaborne research infrastructures together with satellite data (observation component); (*) to develop new datasets and archives of the continuous, comprehensive data flows in a joint manner (data component); (*) to implement validated and harmonized data products in models of appropriate spatio-temporal scales and topical focus (modelling component); (*) to evaluate impact on society though assessment, scenarios, services, innovations and new technologies (society component).

Deadline for abstract submission is 12 January 2022. See more details on topics of the PEEX session at: https://meetingorganizer.copernicus.org/EGU22/session/43890
