The Arctic is warming two times faster than the other regions of the Earth system. Spatially, the processes called “Arctic greening” and the Arctic tundra “browning” are bringing the Arctic change closer to the dynamics taking place in the boreal regions. To be able to understand the changing Arctic environments and societies as well as feedbacks between the Arctic and boreal regions and, on a larger scale, between the Arctic and the Earth system, we need a novel conceptual framework of research methods, infrastructures and procedures. The Pan-Eurasian Experiment Program (PEEX), established in 2012, is aiming to be a next-generation natural sciences and socio-economic research initiative using excellent multi-disciplinary science with clear impacts on future environmental, socio-economic and demographic development of the Arctic and boreal regions and China. PEEX is also a science community facilitating novel research infrastructures (in situ observation networks) in the Northern Pan-Eurasian region and China. PEEX delivers conceptual plans of coherent, coordinated, comprehensive in situ measurement and data systems of the Earth surface-atmosphere interactions. PEEX is making an assessment of the existing observation capacities including satellites, versus the future PEEX in situ observation network, which would cover the Northern Eurasian region from Scandinavia to East Asia. The principles of the PEEX in situ observation network is based on the SMEAR (Stations Measuring the Earth Surface – Atmosphere Relations) concept. PEEX is interested in expanding the land-based observation network to cover also the most relevant processes related to the Arctic Ocean and to make a conceptual design of the marine in situ component. In addition, PEEX is taking the first steps for implementing the seamless all-scales-modelling platform and continues to develop the PEEX View Modelling Tool.
