3 GMES is an EU led initiative Services Component led by EC GMES components Produces information services in response to European policy priorities in environment and security Relies on data from in-situ and space component In-situ component led by EEA Observations mostly within national responsibility, with coordination at European level Space Component led by ESA Sentinels - EO missions developed specifically for GMES: Contributing Missions - EO missions built for purposes other than GMES but offering part of their capacity to GMES (EU/ESA MSs, EUMETSAT, commercial, international)

4 Role of ESA in GMES: Space Council Resolution Coordinator of the overall GMES Space Component Definition of overall GSC architecture; plan for future evolutions; organisation of data access; ensuring operation of Sentinels Development and procurement Agency for dedicated space infrastructure Development of first spacecraft and ground segment; procurement of recurrent elements Interim operator of Sentinel-1, -2 and Sentinel-3 (land) Note: EUMETSAT is proposed operator of Sentinel-3 (Marine), Sentinel -4 and -5

5 Content of ESA GSC programme (after CM-08) Sentinel-1 A: Phase B2/C/D/E1. Sentinel-1B: up to flight readiness Sentinel-2 A: Phase B2/C/D/E1. Sentinel-2B: up to flight readiness Sentinel-3 A: Phase B2/C/D/E1. Sentinel-3B: up to flight readiness Sentinel-4 (MTG-S): Phase Segment B/C/D/E1 2 (2 units) Sentinel-5 (post-eps): Phase B1 & pre-development Sentinel-5 pre-cursor: Phase A/B/C/D/E1 (UV-NIR instrument provided by NL) Ground Segment Development for Sentinel-1, -2, -3 A & B Data Access (data procurement & management) GSC Evolution Studies, incl. low-inclination altimetry

6 GMES dedicated missions: Sentinels Sentinel 1 SAR imaging All weather, day/night applications, interferometry Sentinel 2 Multispectral imaging Land applications: urban, forest, agriculture,.. Continuity of Landsat, SPOT Sentinel 3 Ocean and global land monitoring Wide-swath ocean color, vegetation, sea/land surface temperature, altimetry Sentinel 4 Geostationary atmospheric Atmospheric composition monitoring, transboundary pollution Sentinel 5 Low-orbit atmospheric Atmospheric composition monitoring (S5 Precursor launch in 2014)

7 Sentinel-1 Sentinel-1: C-band SAR mission Applications: monitoring sea ice zones and the arctic environment surveillance of marine environment monitoring land surface motion risks mapping in support of humanitarian aid in crisis situations 4 nominal operation modes: strip map (80 km swath, 5X5 m res.) interferometric wide swath (250 km swath, 20X5 m res.) extra wide swath (400 km swath, 25X100 m res.)
