MONITORING WEATHER AND CLIMATE FROM SPACE Challenges in the provision of large data sets to multiple user communities 14-16 July 2014, Boulder CO Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 1 Mission Statement We are the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). EUMETSAT is an intergovernmental organisation and was founded in 1986. Our purpose is to supply weather and climaterelated satellite data, images and products • 24 hours a day, • 365 days a year to the National Meteorological Services of our Member and Cooperating States in Europe, and other users worldwide. www.eumetsat.int Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 2 EUMETSAT Headquarters (Darmstadt, Germany) Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 3 EUMETSAT Data Services - High Level Overview Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 4 EUMETSAT Data Services - Data Flows EUMETSAT GROUND INFRASTRUCTURE Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 5 EUMETSAT Earth Observation Portal Single Access Point One stop shop Data discovery User registration (>10.000) Subscription for data services: Near-real time data Online Data Access Long Term Archive Additional Image Gallery (WMS/ WCS) User Notifications Operational Real-Time Services Status Indicator Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 6 EUMETCast Dissemination Near Real Time data delivery to users in 3 continents via Satellite 4 3 500+ 201-500 51-200 11-50 2-10 1 User 0 User Users (2/2014) 3,280 users worldwide, 4168 stations 5 new users per month EUMETCast Americas SES 6, C-BAND EUMETCast Africa EUTELSAT 5 WEST A, C-BAND EUMETCast Europe EUTELSAT 9 A, KU-BAND Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 7 EUMETCast Dissemination: Integrating terrestrial dissemination Improving Data Mobility & Management for International Climate Science, Michael.Schick@eumetsat.int & Lothar.Wolf@eumetsat.int 8 MULTICAST ACCROSS GÉANT and NREN INFRASTRUCTURE Exploring the multicast usage on GÉANT infrastructure in Europe and their world wide connectivity; 2011 Proof of concept on terrestrial multicast on GÉANT test bed 2012 3 month feasibility study on terrestrial multicast via GÉANT 2013 Multicast test to KMA Korea 2014 Multicast test to NOAA (Boulder) 2014 Start of 2 year prototype emulating operational scenarios of multicast across Europe and our overseas partners using GÉANT, NREN, I2 and Teint infrastructure.
