CM SAF
The Satellite Application Facility on Climate Monitoring (CM SAF) is dedicated to the high-quality long-term monitoring of the climate system's state and variability, partly on the regional level. It supports the analysis and diagnosis of climate parameters in order to detect and understand changes in the climate system. The SAF furthermore serves the modelling of the atmospheric system as well as planning and management purposes.
