Global SMEAR is an initiative towards integrated Earth observatory initiated by Academician Markku Kulmala and coordinated by INAR. It is collaborating with the European research infrastructures  such as ICOS, ACTRIS, ANAEE and eLTER. Global SMEAR approach is based the "Stations Measuring Earth Surfaces and Atmosphere Relations" (SMEAR) concept, which has been developed at the flagship observatory "SMEAR II" in Finland (61°51' N, 24°17' E) with the longest and most comprehensive measurement series in the world on atmospheric aerosols and energy flows since 1995. A long-term vision is to have, within 10-15 years, a network of 600-1000 highly instrumented environmental observatories carrying out observations on Earth surface - atmosphere relations: concentrations, profiles, fluxes, processes and feedbacks across disciplines.
