New paper in Atmospheric Pollution Research

New results in this recently published paper propose improved nitrogen dioxide (NO2) to nitrogen oxide (NOx) scaling factors for several data-driven methods that are used for the estimation of NOx power plant emissions from satellite observations of NO2. The results from this work led by the Finnish Meteorological Institute will be utilized in the data […]

Improvements to monitoring the freeze/thaw state with radar satellites

The new study presents significant improvements to the existing methods, such as taking into consideration changes in the summer season. Soil F/T information is useful, for example, for users of heavy equipment, such as forestry machines. Soil freezing has a significant effect on the bearing capacity. Soil freeze/thaw (F/T) state in the boreal forest was […]

New model for snow reflectivity may enhance satellite measurements of carbon dioxide in the Arctic

New radiative transfer simulations at the Finnish Meteorological Institute will likely improve satellite remote sensing of carbon dioxide and therefore advance the study of the carbon cycle in the Arctic regions. The simulations support the planning of the European CO2M satellite mission. Doctoral researcher Antti Mikkonen at the Finnish Meteorological Institute devised a mathematical description […]

Treasure chest of interdisciplinary and year-round Arctic climate system data publicly available

The year-round expedition into the central Arctic called “Multidisciplinary drifting Observatory for the Study of Arctic Climate” (MOSAiC) explored the Arctic climate system to gain fundamental insights that are key to a better understanding of global climate change. While anchored to a sea-ice floe, the German research icebreaker Polarstern passively drifted with the Transpolar Drift […]

New study quantifies the temperature inside tropical forests

Temperature is a fundamental factor defining the survival, growth, and reproduction rate of species living inside tropical forests. New study provides maps of temperature inside tropical forests that can be used by ecologists to improve the reliability of species distribution models. New worldwide estimates of temperatures inside tropical forests show that global warming may have […]

Climate Data Records of the Northern Hemisphere snow mass produced by FMI-Space used to assess the human impact to snow loss

The increasing fleet of Earth observing satellites has been a game changer in the monitoring of cryosphere. New analysis shows that human-induced emissions have caused decreases to snow mass in latitudes south of the 60 degrees, whereas the impact has been the opposite to northern latitudes. Consequently, results indicate that drastic decreases in river discharges […]

Machine learning and satellites produce immediate carbon dioxide flux predictions

Satellite observations and existing carbon dioxide flux estimates can be used to train a machine learning algorithm capable of making quick and accurate flux predictions. Researchers at the Finnish Meteorological Institute investigated a new approach using a random forest, a type of machine learning model, to predict future CO₂ fluxes. The model was trained with […]

Forest fragmentation is changing the shape of tropical trees – why does this matter for climate change? 

Researchers used laser scanning to map out how the fragmentation of forests affects tree shape in the rainforests of Brazil. The results shed light on the impact of human activity on the tropical environment and on climate change in a new way. Until now, there haven’t been comprehensive studies to measure how forest fragmentation impacts […]

Satellites capture socioeconomic disruptions during the 2022 full-scale war in Ukraine

Satellite observations show significantly reduced air pollution levels over the major Ukrainian cities, power plants and industrial areas. Since February 2022, the full-scale war in Ukraine has been strongly affecting society and economy in Ukraine. Satellite observations provide crucial information to objectively monitor and assess the impacts of the war. A new paper published on Scientific […]
