The Finnish Meteorological Institute is a leading expert in meteorology, air quality, climate change, earth observation, marine and arctic research areas.
FMI's researchers publish about 300 peer-reviewed articles annually.
In Science News we publish current information about FMI's studies on the weather, the sea and the climate.
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.

FMI researchers produce some 300 publications annually, the majority of them in international scientific journals. Research results are also published in FMI´ss own publications series. FMI`s own series are:
* FMI Contributions: high-quality peer-reviewed research results, mainly doctoral dissertations
* FMI Reports: current research results mainly for customers and other stakeholders
All publications from 2016 onwards can be found on Helda.
