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.

Estimations about sea ice made in Bohai Sea

Estimations about sea ice made in Bohai Sea

Finnish Meteorological Institute has been doing estimates of two essential sea ice parameters—namely, sea ice concentration (SIC) and sea ice thickness (SIT)—for the Bohai Sea using a combination of a thermodynamic sea ice model and Earth observation (EO) data from synthetic aperture radar (SAR) and microwave radiometer.

"We compare the SIC and SIT estimation results with in-situ measurements conducted in the study area and estimates based on independent EO data from near-infrared/optical instruments. These comparisons suggest that the SAR-based discrimination between sea ice and open-water works well, and areas of thinner and thicker ice can be distinguished", says researcher Juha Karvonen. Still, more  comprehensive training dataset is needed to set up an operational algorithm for the estimation of SIC and SIT.

Work was partly supported by the National Key Research and Development Program of China (2016YFC1401007, 2016YFC1402704), the National Natural Science Foundation of China under contract No. 41428603 and the Academy of Finland under contract No.283101, and the International Science and Technology Cooperation Project of China under contract No. 2011DFA22260. ECMWF is acknowledged for making the weather forecast data available.
