Atmospheric sciences

The main research activities are  i) climate change research, ii) climate change and air quality interactions, iii) aerosol and environmental physics, (iv) micrometeorology and forest-atmosphere relations, and (v) dynamical meteorology.

The core of the research is the understanding of energy, mass and momentum transfer and phase transitions. Theoretical, modelling and experimental studies of nucleation, condensation/evaporation and atmospheric aerosol dynamics have continued in 2014. Studies of deposition and fluxes of atmospheric gases, cloud microphysics, atmospheric radiation, mesoscale meteorology, and climate and radar meteorology were performed.

SMEAR II station

Have a tea with a tree; During the first Climate Whirl art residency at SMEAR II station media artist Agnes Meyer-Brandis stayed at the station for three months studying the research done at the station on climate-forest interactions. A permanent art work Tealemetree Station Hyytiälä was opened during the SMEAR II 20 year’s anniversary. (Permanent Tealemetree Station Hyytiälä, Agnes Meyer-Brandis © VG Bildkunst)

Researchers operate together with the researchers of the Department of Forest Sciences at versatile field stations: SMEAR I (Station for Measuring Forest Ecosystem-Atmosphere Relations) station in Värriö (Lapland), SMEAR II station in Hyytiälä, and SMEAR III (urban SMEAR) in Kumpula Campus. Particularly SMEAR II has turned out to be a leading station in its research field due to its comprehensive research program and to its unique time series of fresh aerosol formation. The development and construction of novel weather radar techniques has been performed in collaboration with Vaisala Oyj. The research at the Division is also linked with the instrumental development work with international companies. The most important one has been Aerodyne Research, Inc. in the U.S.A. The co-operation concerns development of high-response greenhouse gas analyzers and the aerosol mass spectroscopy technique.
The international Master programme "Atmosphere-Biosphere Studies" has continued its operation together with the national graduate school. Three Nordic Centers of Excellence CRAICC (Cryosphere-Atmosphere Interactions in a Changing Arctic Climate, coordinated by Markku Kulmala), DEFROST (Impacts of a changing cryosphere - depicting eco-system-climate feedbacks from permafrost, snow and ice), and SVALI (The Stability and Variations of Arctic Land Ice) started in 2010, and will continue until 2015. In addition to these, ESTICC (E-Science Tools for Investigating Climate Change at High Northern Latitudes) project goes on. It develops e-science tools to analyse, amongst other, the Arctic Change and to improve the forecasts of the climate change in Arctic areas.
A project office "Integrated Land Ecosystem – Atmosphere Processes Study" (iLEAPS) has continued its work related to land-atmosphere interactions within the International Geosphere – Biosphere Programme (IGBP). The iLEAPS project aims at advancing new integrated experimental and modelling research approaches needed in the Earth System.
The researchers have coordinated and participated in several international projects, and organized a number of international workshops, conferences, and measurement campaigns in Finland and abroad.
They have also innovated and participated various scientific outreach efforts.
