1. CAPACITY Final Presentation, 2 June 2005, ESTEC Operational Atmospheric Chemistry Monitoring Missions (“CAPACITY”) Final Presentation ESA-ESTEC, Noordwijk / NL, 2 June 2005

2. CAPACITY Final Presentation, 2 June 2005, ESTEC Introduction

3. CAPACITY Final Presentation, 2 June 2005, ESTEC Two branches of ESA’s Earth Observation Programme  Earth Explorer  research and demonstration missions  programme based on science community proposals and scientific evaluation  4 missions under development and 2 in preparation  7 th mission to emerge from current call for ideas  Earth Watch  operational (or commercial) missions  applications to serve user community beyond science  possible partners: EU (GMES), Eumetsat, others “CAPACITY” is directed towards the Earth Watch programme.

4. CAPACITY Final Presentation, 2 June 2005, ESTEC Earth Watch / GMES Five “Sentinels” considered between EU and ESA: 1.C-band SAR (interferometry) 2.Superspectral imager (Landsat, SPOT continuity) 3.Radar altimeter and multispectral sensor for ocean watch and global land monitoring 4.Geostationary atmospheric composition for pollution monitoring 5.Atmospheric composition sounding in low Earth orbit  Definition studies for sentinels 1-3 starting  Phase 0 studies for sentinels 4-5 starting late 2005  GMES programme proposal in preparation  ESA Ministerial Council Dec. 2005, EU end of 2006

5. CAPACITY Final Presentation, 2 June 2005, ESTEC Eumetsat future programmes Meteosat Third Generation (geostationary orbit)  Pre-phase A system studies ongoing  Current payload: imager(s), IR sounder, lightning detector  UV-vis sounder study on instrument level, no satellite accomodation studied (funding envelope)  2 nd user workshop held recently Post-EPS (polar orbit)  User consultation starting (Application Experts Groups)

6. CAPACITY Final Presentation, 2 June 2005, ESTEC Sources of user requirements IGOS-IGACO Theme report EU GMES-GATO report Eumetsat user consultation in the frame of MTG GMES service element PROMOTE EU FP projects, e.g. Create-Daedalus, Evergreen GCOS implementation plan, WCRP-SPARC long-term observation requirements Environment and climate protection protocols, directives etc. (EU, international) CAPACITY workshop Jan. ’04 ESA studies on CO 2 monitoring ESA study on atmospheric chemistry observation requirements (research)
