The Unit consists of three research groups with a staff of approximately 35 persons. The main research topics are: atmospheric modelling, meteorological applications and meteorological remote sensing. The Unit acts as a meteorological expert especially in connection with safety issues in close co-operation with the Services Development Unit of the Weather and Safety Directorate.
Numerical Weather Prediction Models
The Numerical Weather Prediction (NWP) Group maintains and monitors a regional high resolution numerical weather prediction system as well as carries out related research, particularly in the context of the international HIRLAM consortium. The NWP-system is capable of predicting the weather over Finland and Europe for about two days ahead. The predictions are utilised in the public weather service and as a basis for many specialized forecasts needed for safe aviation, shipping and traffic on roads and rail. Additionally, they are used when forecasting air quality and dispersion of pollutants. The regional numerical weather prediction system is complementary to global systems operated in international cooperation.

The Meteorological Applications Group performs research and develop meteorological methods (e.g. probabilistic forecasts), specific weather forecasting systems (e.g. road weather) and forecast verification methods. The Group also participates in the development of methods for environmental research and monitoring. In addition, the group is involved in the development of telematic services (intelligent traffic) as well as in wind energy related surveys and research.

Satellite and Radar Applications
The activities of the Satellite and Radar Applications Group focus on meteorological remote sensing applications, such as performing research on weather satellite and radar signals and images to be applied in the weather service. Its research topics include for example methods for the detection of fog, severe convection and hail as well as determination of the phases (rain, snow, sleet) of the precipitation. The Group also studies the assimilation of satellite and weather radar observations into weather prediction models in co-operation with the NWP Group. Remote sensing education and international activities are an integral part of the Group's activities.
