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.

A more precise description of the microphysics of radiation fog will improve fog forecasts

A more precise description of the microphysics of radiation fog will improve fog forecasts

Measurements and modelling results show that the descriptions of the properties of fog used with weather forecasting models are imprecise. By improving the fog model it is possible to predict visibility more accurately and estimates of when the fog will clear.

Radiation fog can form on clear nights in areas where the land surface cools dramatically and the atmospheric mix is poor. In such circumstances fog droplets form around the aerosol particles in the same way as cloud droplets form in clouds, and the models often use the same descriptions for the microphysics of both fog and low clouds.
