The PEEX China kick off meeting was held in November 2013. During its five years in operation, the program has established a governance structure and delivered a science plan for the Northern Eurasian region. PEEX has also introduced a concept design for a modelling platform and ground-based in situ observation systems for detecting land-atmosphere and ocean-atmosphere interactions. Today, PEEX has an extensive researcher’s network representing research communities coming from the Nordic countries,RussiaandChina. PEEX is currently carrying out its research activities on a project basis, but is looking for more coordinated funding bases, especially inRussiaand inChina. The near-future challenge in implementing the PEEX research agenda is to achieve a successful integration and identification of the methodological approaches of the socio-economic research to environmental sciences. Here we give insight into these issues and provide an overview on the main tasks for the upcoming years.</p></abstract><kwd-group xml:lang="en"><kwd>multidisciplinary approach</kwd><kwd>multiscale research</kwd><kwd>global grand challenges</kwd><kwd>arctic-boreal environment</kwd><kwd>observation networks</kwd><kwd>modelling platform</kwd><kwd>land-atmosphere interactions</kwd><kwd>the Arctic Ocean</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Alekseychik P., Lappalainen H.K., Petäjä T., Zaitseva N., Heimann H., Laurila T., Lihavainen H., Asmi E., Arshinov M., Shevchenko V., Makshtas A., Dubtsov S., Mikhailov E., Lapshina E., Kirpotin S., Kurbatova Yu., Ding A., Guo H., Park S., Lavric J.V, Reum F., Panov A., Prokushkin A., and Kulmala M.
