The PEEX Session on the Observation, Modelling and Assessment in the Arctic-Boreal Domain in collaboration with AASCO (Arena for the Gap Analysis of the Arctic Science Co-operation; https://www.atm.helsinki.fi/peex/index.php/aasco) – DBAR (Digital Belt and Road programme; http://dbeltroad.org) / /CBAS (International Research Center of Big Data for Sustainable Development Goals; https://sdg.casearth.cn/en/aboutCBAS) initiatives is planned for the General Assembly of the EGU-2023 (European Geosciences Union; https://www.egu23.eu, Vienna, Austria, 23–28 April 2023).

The session convener: Dr. Hanna K. Lappalainen & co-conveners: Acad. Markku Kulmala, Dr. Alexander Mahura from the University of Helsinki, Finland, and Prof. Alexander Baklanov from the World Meteorological Organization (WMO), Switzerland.

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