Description

The SMEAR III station started in Helsinki in autumn 2004. The site expands the versatile atmospheric measurements to an urban area where the anthropogenic impacts are more evident. The instrumentation covers aerosol dynamics, atmospheric chemistry, micrometeorology, weather monitoring and ecophysiology of trees growing in the urban environment. The most characteristic features of the station are its location at high latitude and the vicinity of sea. The station is operated by the University of Helsinki and the Finnish Meteorological Institute (FMI).

Scientific scope

The SMEAR III science scope is linked to urban air quality. The multidisciplinary science scope include analysis of air quality and urban landscape interactions, impact of traffic and urban greenery to air quality and carbon sequestration and emissions from urban landscapes.
