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.
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.
A new method for monitoring soil frost/thaw state in boreal forest environments was developed. The method enables nearly daily monitoring in a 1 km spatial resolution.
The study investigated how the European Sentinel-1 synthetic aperture radar satellite can be used for the estimation of soil frost/thaw (F/T) state in the boreal forest zone. The method allows almost daily monitoring in a 1 km spatial resolution from Finland, and possibly from other northern regions as well. The method can be beneficial for example to users of heavy equipment such as forest harvesting operators, who need up to date information about the bearing capacity of the terrain, which highly depends on the soil F/T state.
The study found that it was easier to estimate the soil state in soils with increased water content, because then, the contrast between the backscatter of frozen and thawed soil was higher. Even though the canopy backscatter is not directly related to the soil conditions, it is useful in estimating the soil F/T state because it is influenced by the air temperature below zero degrees, and by the snow properties.
The research was lead by Space and Earth Observation Centre (FMI-SPACE) scientists.
