The Station for Measuring Earth surface – Atmosphere Relations, SMEAR, is a unique research infrastructure concept in its comprehensiveness. SMEAR station is an integrated and sophisticated approach to observe in-situ 24/7 and in a coherent way material and energy exchange between the atmosphere and the Earth surface. It is designed to provide high quality, unbiased data and associated metadata on land, aquatic and urban Earth surface–atmosphere interactions to enhance understanding from nano-scale to global feedback loops. Measurement data is aimed to be open and easily accessible for international multidisciplinary research community.
