Pan-Eurasian Experiment (PEEX) Programme – Overview on the recent results

Pan-Eurasian Experiment (PEEX) Programme (www.atm.helsinki.fi/peex) initiated in 2012 is an asset for INAR at the University of Helsinki and its co-partners to have high international visibility, to attract further research collaboration and to upscale the scientific impact in various arenas. The PEEX is interested in the northern high latitudes (Arctic, boreal) and on China and the new Silk Road Economic Belt regions. The PEEX scientific focus is on understanding of large-scale feedbacks and interactions between the land -atmosphere - ocean continuum under the changing climate of the Northern high latitudes and at the Arctic (Kulmala et al. 2015, Lappalainen et al. 2014; 2015; 2016; 2018, Vihma et al. 2019, Alekseychik et al. 2019, Kasimov et al. 2018) and on the transport and transformation of air pollution in China. PEEX research results have been published the PEEX Special Issue in J. Atmospheric Chemistry and Physics (www.atmos-chem-phys.net/special_issue395.html), in the Journal “Geography, Environment, Sustainability” (ges.rgo.ru/jour) and in the J. Big Data (journalofbigdata.springeropen.com).  In 2019 PEEX started comprehensive analysis on the first results over last five years based on the published peer review papers and results attained from the PEEX geographical domain.  The aim of the analysis is to study the state-of-the-art research outcome versus the PEEX large-scale research questions addressed by the Science Plan (Lappalainen et al. 2015). To facilitate the direct input from the research community, we have asked researchers to answer to a form where they could list their main scientific results and activities considered relevant to PEEX region and also include ancillary information such as type of activity or geographical extend. The preliminary metadata database covers information from over 400 scientific papers and the analysis is in progress. The key gaps of current understanding and future research needs will be discussed from the system point of view, from the land ecosystems, atmosphere, ocean & river systems and society perspectives and preliminary results will be introduced at EGU PEEX session.
