UN-SPIDER Knowledge Portal
Help Shape the Future of the UN-SPIDER Knowledge Portal
The UN-SPIDER Knowledge Portal is your one-stop platform for resources on space-based disaster risk management. It provides: • Links and guidance on satellite data sources and applications • Recommended practices and step-by-step methodologies • Training materials and tutorials • Case studies and user stories from real-world applications • News and updates on UN-SPIDER activities, events, and global developments
Since its last major review in 2012, the Portal has evolved significantly. Now, we want to hear from you.
We invite you to take part in the 2025 evaluation of the UN-SPIDER Knowledge Portal!
The Sentinel-6 Michael Freilich satellite was launched into orbit on November 21, 2020. The launch was a culminated European-American effort that involved organisations from both sides of the atlantic. The European Space Agency (ESA), the European Organisation for the Exploitation of Meterological Satellites (EUMETSAT), the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA) and the National Centre for Space Studes (CNES) all collaborated together to make the launch of Sentinel-6 Michael Freilich a reality. The Sentinel-6 Michael Freilich satellite is the first of the Sentinel-6 satellites. An identical satellite, Sentinel-6B will follow in 2025. At an altitude of 1336 km the Sentinel-6 Michael Freilich satellite will use instruments on board to provide highly accurate measurements of the sea level in an effort to combat climate change and support weather forecasting. The data will also be used in the case of disaster management and emergency relief efforts globally. With it, disaster management professionals will be able to better predict and tackle climatological (forest fires, glacial lake outburst, drought), hydrological (landslide, flood) and meteorological (severe storm, extreme temperature) disasters.
