20 Sentinel Open Hub: Free and Open Access to Sentinel data (previously called Scientific Hub) Access through self-registration Automated download scripting capability and dedicated API-Hub Restriction on concurrent downloads More than 100,000 users registered 2 Million Sentinel-1 products are available on-line for download, representing about 3 PB of data. More than 14 PB of data downloaded by users. ESA UNCLASSIFIED - For Official Use Sentinel-1 Mission Status ESA Slide 20

21 Sentinel-1: concluding remarks Sentinel-1 mission routine operations on-going, overall mission in a very good shape High quality data routinely provided to Copernicus Services, Member States, International partners and to a wide spectrum of user communities worldwide for various thematic applications The mission provides: global and routine coverage, with a systematic production scenario, open and free data access, the long-term perspective, to further bring SAR applications into the operational domain, at local, national, regional, continental and global scale ESA UNCLASSIFIED - For Official Use Sentinel-1 Mission Status ESA Slide 21

22 Sentinel-1 applications ever increasing Sea ice and iceberg monitoring Maritime surveillance: oil spill monitoring, ship detection, illegal fisheries, etc. Sea state: wind, wave Land use, agriculture, forestry, logging, land classification, urban planning Ground deformation: subsidence, landslides, earthquakes, volcanoes, infrastructure monitoring Ice sheets, glaciers, climate change Emergency management Soil moisture, wetland Snow, permafrost, avalanches, ESA UNCLASSIFIED - For Official Use Sentinel-1 Mission Status ESA Slide 22

23 ESA Heritage Data still a considerable user interest ERS and Envisat data constitute the main ESA heritage data Data value & utilization increase if part of long time data series (e.g. continuity with Sentinels) New ERS/Envisat user projects registered in 2017 (Sept) Growing interest in Heritage SAR Data for time continuity with Sentinel ENVISAT ERS GOCE SMOS CRYOSAT SWARMESA CampaignsPROBA-1 PROBA V TPM ESA UNCLASSIFIED - For Official Use Sentinel-1 Mission Status ESA Slide Statistics at Sep 2017 Sentinel user stats not included
