Satellites provide unprecedented amounts of atmospheric composition measurements every day, with a near-global coverage. These are evaluated with high-quality ground-based retrievals.
We at FMI-SPACE have a strong role in production of satellite data and long observational time series through European collaboration, including the leadership of EUMETSAT’s AC SAF project. We create applications from satellite observations for environmental monitoring and decision making. In addition, we develop data-driven methods for interpretation, validation and uncertainty quantification of remote sensing measurements.
FMI-SPACE hosts extensive ground-based greenhouse gas measurements at Sodankylä in Northern Finland, including continuous high-resolution FTIR retrievals in the Total Carbon Column Observing Network since 2009, and regular AirCore flights. These measurements are vital for validation of increasing volumes of satellite observations at high latitudes, and currently support all key GHG satellite missions: Sentinel 5P TROPOMI, TanSat, Orbiting Carbon Observatory -2, and the Greenhouse Gases Observing Satellite.
