Welcome to ACTRIS Estonia

ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure), a pan-European research infrastructure producing high-quality data and information on short-lived atmospheric constituents and on the processes leading to the variability of these constituents in natural and controlled atmospheres. ACTRIS Research Infrastructure consists of national measurement networks which are run and funded by national institutes, universities and funding agencies in ACTRIS member countries.

ACTRIS Estonia is the current national consortium to enable Estonian participation in the European Research infrastructure ACTRIS.

It consist of the SMEAR Estonia station, an atmopshere-ecosystem super site to assess the dynamics of matter and energy of the terrestrial boundary layer. With its 130m heigh atmospheric tower and several scaffolding towers in different ecosystems and regions over Estonia. It is the core of the ACTRIS Estonia network.

The Tahkuse Air Monitoring Station has been developed according to the possibilities since the times of the Soviet Union after 1984. Air quality studies conducted at Tahkuse have been part of the National Environmental Monitoring Program since 1994. It provides long-term systematic complex physical and chemical measurements of the atmosphere and pollution parameters. Measurement data allow for the study of relationships between measured parameters and the dependence of air pollution and its spread on meteorological parameters.

The Tartu Observatory provides remote sensing data and radiation measurements.

The national roadmap project is linked to the Estonian Environmental Observatory infrastructure.
