2 PROBA-V operational setup ESA owns the Proba-V mission and its data, it will be handed over from D/TEC to become an Earthwatch mission under responsibility of ESA s Earth Observation Directorate after Commissioning Phase, around ~Nov 2013 The mission will be managed from ESRIN, ESA s centre for Earth observation in Frascati/Italy, with Delegation of tasks ESA-internal to Redu for Flight Operation Segment/ Mission Control Center (MCC) D/TEC for satellite maintenance as well as industrial contracts to VITO for the Payload Data Ground Segment, collocated with SPOT-VEGETATION processing. Ground Receiving Station(s): to be selected via open tender ESA will be responsible to manage user access to/exploitation of the 1km products within Earthwatch, under an ESA free and open data policy, based on the Principles of the Sentinel data policy ESA UNCLASSIFIED For Official Use ESA's Esrin Centre in Italy ESA's Redu Centre in Belgium

15 Sentinel 3 Overview We care for a safer world The Sentinel 3 Mission is an operational mission in high-inclination, low earth orbit Full performance achieved with 2 satellites in orbit Sentinel-3 implements 3 core missions to deliver continuity to existing ones: Sea Surface Height products (Credit: CLS) Sea and land colour data, at least at the level of quality of the Medium Resolution Imaging Spectrometer (MERIS) instrument on ENVISAT Sea and Land surface temperature, at least at the level of quality of the Advanced Along-Track Scanning Radiometer (AATSR) instrument on ENVISAT Sea surface topography data at least at the level of quality of the Envisat Radar Altimeter (RA) system In addition, the payload design will allow data continuity of the medium resolution Vegetation instrument (on SPOT4/5) measurements, enhanced fire monitoring capabilities, Along-track SAR for coastal zones, based on Cryosat-2 heritage, for improved in-land water and sea-ice topography. Sea Surface Temperature products (Credit: Met Office) Ocean colour products (Credit: MyOcean) Land cover products (Credit: ESA)

Full Resolution 300m over land/ocean, d. improved characterisation, e.g., straylight, camera overlap e. improved (1 sat) coverage Ocean < 4 days, Land < 3 days (MERIS 15 days) f. 100% overlap with SLSTR

18 SYNERGY Products The Synergy processor of Sentinel-3 makes use of the combined information from the OLCI and SLSTR instruments to provide improved data for land surface analysis. The Synergy L2 processing uses of the enhanced spectral and angular capabilities of a combined instrument (the SYN instrument) to produce a product with atmosphere-corrected surface reflectance and aerosol properties. Synergy VGT processing provides products comparable to SPOT VGT-P and VGT-S. SYN Surface Reflectance SYN Fully atmosphere-corrected Surface Reflectance and associated error estimates. Synergistically retrieved from OLCI channels and SLSTR channels (both nadir and oblique views), except for gaseous absorption channels. SYN Aerosol Optical Depth SYN Aerosol Optical Depth SYN Aerosol Model Index Top of Atmosphere Reflectance product provided for the continuity of the SPOT VGT P product. Generated from atmosphere-corrected OLCI and SLSTR channels interpolated to VGT bands and upscaled to top of atmosphere reflectances. Aerosol load, expressed in optical depth at a given wavelength (550 nm), and associated error estimates. Synergistically retrieved from OLCI and SLSTR. Single view, three channel aerosol-robust SST Index into the table of 40 aerosol models used for retrieving the SYN Aerosol Optical Depth.
