Research on three branches of activity

High-quality research is utilized to develop services to benefit our everyday life. Visible examples are improvement of weather forecasts, development of new expert and warning services as well as applications of the newest research results.

The meteorological and marine research programme does basic and applied research on meteorology, atmospheric science and physical oceanography. Research subjects include forecast models for different time frames, scientific applications and remote sensing observations linked to the research area as well as the effects of climate change and how to adapt to them.
 
The climate research programme does basic and applied research on the different components of the climate system. The research subjects are especially past, current and future climate as well as the composition of the atmosphere and its effects on climate change and air quality. Some of the employees of the programme work at the office in Kuopio.
 
The space and earth observation centre is responsible for the research of the polar regions and near space as well as developing technology related to the activity. The research subjects are especially arctic research and remote sensing, new observation methods and space. The Arctic Space Centre and Sodankylä office are a part of the Space and earth observation centre.

Emissions from small-scale woodburning undergo changes within the atmosphere

Emissions from small-scale woodburning undergo changes within the atmosphere

Research carried out by the Finnish Meteorological Institute and the University of Eastern Finland studied the change processes for small-scale woodburning emissions both in darkness and in simulated daylight.

In fresh combustion gas, the majority of organic compounds are carbonyls (such as acetaldehyde) and aromatic compounds (such as benzene). As the emissions age within the environmental chamber, the concentrations of gaseous organic compounds decreases significantly. In contrast, an increase in the mass of organic compounds was observed for the particulates contained within the emissions.

The ageing of the emissions proceeded differently in darkness compared to daylight. In dark conditions, a lot of organic compounds containing nitrogen were formed, including both gaseous and particulate forms. In daylight conditions, in contrast, there was an increase in concentrations of certain gaseous carbonyls, and particularly of acidic anhydrides.
