Earth Observation

Earth Observation (EO) satellites are essential tools to provide information on the state and processes of the Earth’s atmosphere, biosphere, hydrosphere, and oceans including the anthropogenic impact to environment and climate. EO research at FMI focuses on • UV radiation • Composition of atmosphere: greenhouse gases, ozone, pollutants, aerosols • Cryosphere: snow, sea and lake ice, soil frost

FMI product on tropospheric NO₂ for the year 2016 based on OMI instrument observations onboard NASA’s Aura satellite. NO₂ is a short-lived polluting gas, produced from fossil fuel combustion. The Ozone Monitoring Instrument (OMI) is a contribution of the Netherlands's Agency for Aerospace Programs (NIVR) in collaboration with FMI to the Aura mission.

An essential part of the research is the use of satellite data - together with climate modelling and in situ measurement data sets - to investigate and quantify key factors of climate change. Additionally, satellite data is used to develop services and products for various end-use applications such as water resources management and forestry, and monitoring of air pollution, forest fires, volcanic plumes, and floods.

Average Northern Hemisphere March snow mass for 1980-2018 based on fusion of space-borne microwave radiometer and in situ observational data (GlobSnow v3.0 product by FMI). Snow mass is given as Snow Water Equivalent (SWE) indicating the depth of water released by instantaneous snow melt. Source: Nature, vol. 581, 21 May 2020.
