New wind data for Mars

Researchers at FMI have decoded images of scattered spacecraft parachutes and heat shields to provide new wind data for Mars. To do this they used simulations of spacecraft landings in conjunction with a machine learning algorithm to infer the winds responsible for scattering the hardware. The work has provided wind data in a region of […]

Measurement campaign studies the effect of solar UV radiation on airborne transmission of viruses in outdoor air

Reasons for seasonality of virus epidemics are still unknown. In Sodankylä, a campaign aims to study the role of solar ultraviolet radiation in virus infectivity. The campaign aims to provide new information about virus transmission in outdoor air and to find explanations to the seasonality of virus epidemics: Why virus pandemics seem to be less […]

Emissions from Eastern Russian oil fields detected from space

Nitrogen oxide (NOx) and methane (CH4) emissions over Tas-Yuryakh and Talakan oil fields in Sakha Republic (Eastern Siberia, Russia) have been estimated using multi-satellite observations. The emissions are linked to oil production and associated gas flaring activities. Crude oil production activities and associated gas flaring are responsible for significant air polluting and greenhouse gas (GHG) […]

Doctoral dissertation: Near real time 3D imaging of the ionosphere

In his dissertation, Johannes Norberg, a researcher at the Finnish Meteorological Institute, developed a computationally efficient method for imaging the Earth’s ionosphere. The ionosphere is the partly ionised region of the Earth’s atmosphere. It starts at an altitude of about 60 kilometers and reaches up to 1,000 kilometers. It has a significant effect for HF […]

Snow samplers were compared to define instrumental bias

Nine different snow water equivalent (SWE) measurement devices we compared in a field campaign organized at the Arctic Space Centre in Sodankylä. Comparison of the different instruments suggests an uncertainty level of around 10 percent. SWE is an important parameter for flood forecasting and water management. Traditionally, different devices based on weighing a snow sample […]

Doctoral dissertation research led to a new satellite-based flood mapping product

In his dissertation, Juval Cohen, a research scientist at the Finnish Meteorological Institute, studied the effect of forest canopy on satellite observations in the northern boreal forest region. Based on the results of the thesis, a first operational satellite-based flood mapping product used at the Finnish Flood Center was developed. The product can detect floods […]

Snow is more important than storms in controlling thermodynamic sea ice growth in the Arctic

Sea ice growth is mainly controlled by the amount of snow on sea ice. This was found out in a study investigating the role of snow and storms in slowing down the Arctic sea ice growth in winter. In recent decades Arctic sea ice has been thinning, and it has become more vulnerable to changes […]

New seasonal forecast service to help with estimating conditions for harvesting timber

Harvesting machines weight about 20 tons and require good bearing capacity of the terrain to avoid the machines from getting stuck and to keep from damaging the topsoil of the forest floor. Up to 80% Finish forest land have been classified for Finnish Foreste center based on analysing airborne laser scanning data for what sort […]

Snow mass of the Planet revealed

FMI-SPACE researchers, together with Environment and Climate Change Canada (ECCC), made a major step in climate research by giving the first reliable estimate on the Northern Hemisphere snow mass. The article “Patterns and trends of Northern Hemisphere snow mass from 1980 to 2018” was published in the most highly ranked scientific journal Nature 21 May […]
