  2. Global Monitoring for Environment and Security GMES Objective GMES Service Development GMES Atmosphere Service GMES Space Component

  3. Global Monitoring for Environment and Security GMES Objective “to provide, on a sustained basis, reliable and timely services related to environmental and security issues in support of public policy makers’ needs” • GMES – Global Monitoring for Environment and Security’ (GMES) is a joint initiative of the European Union and the European Space Agency (ESA) • Represents a concerted effort to bring data and information providers together with users • Make environmental and security-related information available to the people who need it through enhanced or new services • European Contribution to the Global Earth Observing System of Systems (GEOSS)

  4. GMES Service Development • Integrated approach combining models, in-situ, and satellite data • Three fast track services: Emergency Response, Land Monitoring & Marine • Pilot GMES Atmosphere Service under development • Service Implementation Groups advise ECwith working groups on • Scope • Architecture • In-situ component • Space component

  5. GMES Atmosphere Service Components • Air Quality • monitoring of global and European atmospheric composition and provision of historic records  threshold exceedance warning, development of effectiveair pollution abatement • integrated global, European & local air qualityanalysis & forecast traffic regulation, air quality alerts, support to health services, extreme events • Climate Forcing • improved and sustainedmonitoring of the state of the climate system(surface and upper air meteorology and composition)and its variability  rapid response toextreme weather events and natural catastrophes • integrated global, European and regional concentration fields of key greenhouse gases (CO2, CH4 and related tracers) enablingdetermination of sources and sinks  support toemission and sink verification and mitigation policy • Stratospheric Ozone and Solar Radiation • improved and sustainedmonitoring of the current status and trendsin stratospheric ozone depletion and ozone depleting gases • routine provision of updatedozone, UV and solar radiation maps and forecasts

  6. GMES Space Component • Sentinel-1 C-band interferometric radar mission • Sentinel-2 multispectral optical imaging mission • Sentinel-3 altimeter and wide-swath low-medium resolution optical and infrared radiometers • Sentinel-4, -5 two families of atmospheric chemistry monitoring missions, one on geostationary (Sentinel-4) and one on low Earth orbit (Sentinel-5) • Sentinels 4&5 will support the GMES Atmosphere Service

  7. Main Gaps in Current / Planned Operational System • High temporal and spatial resolution space-based measurements of tropospheric (PBL) composition for application toair quality • Climate gases(CO2, CH4 and precursor CO) andaerosol monitoringwith sensitivity to the PBL • High vertical resolution measurementsin the UT/LS region for ozone and climate applications

  8. Mission Concepts Mission concept forclimate protocol monitoring(lower troposphere) and air qualityapplications Instrumentation: • UV-VIS-NIR-SWIR spectrometer for O3, NO2, SO2, H2CO, CH4, CO, aerosol • thermal IR sounder for O3, CO and CH4 profiles and HNO3 • cloud imager System:Sentinel 4:GEO platform (Europe, reduced set of species) Sentinel 5:sun-synchronous LEO platform Note: A Sentinel 5 precursor with a launch date of 2014 is also planned to ensure data continuity and to support development of operational services

  9. Mission Concepts Mission concept forozone and climate applications in the UTLS Instrumentation options: either mm-wave (MASTER derivative) or mid-IR (AMIPAS derivative) limb-sounder System: sun-synchronous LEO platform Maturation of application to be pursued. Choice of instrument type open. Mission to be considered after clarification of these points.

  10. GAS Implementation Group WG 4 Recommendations (Space) • Sentinel 4 will be a realised as • addition of a UVN spectrometer on the EUM MTG-S platforms (~2018) • utilisation of TIR data from the EUM IR sounder onboard the same platforms and • utilisation of imager data from the EUM MTG-I platforms (~2015) • Sentinel 5 will consist of • a UVNS spectrometer embarked on the EUM post-EPS platforms (~2020) • implementation of the Sentinel 5 IR sounding requirements in addition to meteorological requirements for the EUM post-EPS IR sounder and • utilisation of EUM post-EPS imager data. • Additionally a UVNS spectrometer (precursor of Sentinel-5) is required in a polar orbit complementary to MetOp, with afternoon equator crossing time

  11. Future EUMETSAT Missions Meteosat Third Generation (MTG) Post-EPS Relationship to Sentinels 4&5

  12. Meteosat Third Generation (MTG) (GEO) • Identification of user requirements supported by a User Consultation Process, also addressing atmospheric chemistry • Based on the assessment of the capabilities of observing techniques there were five candidate observation missions identified for MTG: • High Resolution Fast Imagery (HRFI) mission • Full Disk High Spectral Imagery (FDHSI) mission • Infrared Sounding (IRS) mission • Lightning Imagery (LI) mission • UV-VIS Sounding (UVS) mission • For further information see www.eumetsat.int  Home Main What_We_Do Satellites Future_Satellites Meteosat_Third_Generation

  13. Post-EPS (EUMETSAT Polar System) (LEO) • Application Expert Groups convened to analyse the needs of EUMETSAT users in the 2020+ timeframe User needs documented in 5 position papers • Atmospheric Chemistry • Atmospheric Sounding and Wind Profiling • Climate Monitoring • Cloud, Precipitation and Large Scale Land Surface Imaging • Ocean Surface Topography and Imaging • Mission Requirements Document (MRD) includes Infra-Red Sounding, UV-Visible-SWIR, Limb MM-Wave & Infra-Red and 3MI missions • For further information see www.eumetsat.int  Home  Main What_We_Do  Satellites  Future_Satellites  Post-EPS

  14. Relation to GMES Sentinels 4&5 – Requirements Analysis • Requirements harmonisation process aimed to achieve convergence between Sentinel 4&5 and MTG and post-EPS requirements level of commonality high MTG and Sentinel 4 (GEO) • For MTG some differences remain between Sentinel -4 UVS and MTG UVS specifications, most notably related to spatial coverage requirements • The MTG Infra-Red Sounder (IRS) primarily targets meteorological applications and the Sentinel -4 IRS purely atmospheric chemistry applications  as a result there are differences in requirements specification Post-EPS and Sentinel 5 (LEO) • High degree of convergence achieved  no significant differences remain • Current specification assures continuity with EPS. • Limb MM-Wave & Infra-Red instruments not currently included in the Sentinel 4&5 MRD • IRS requirements for Atmospheric Chemistry in the post-EPS framework have priority “2” relative to all other candidate Missions for post-EPS

  15. Relation to GMES Sentinels 4&5 – Schedule MTG versus Sentinel 4 • With the MTG twin-satellite configuration there is now a possibility to embark a UVS mission similar to the UVS studied during MTG Phase 0 (payload mass ~ 140 kg) • Final decision to embark Sentinel 4 on the MTG sounding satellites has to be taken in late summer 2008 together with the definition of the MTG payload complement Post-EPS versus Sentinel 5 • UVNS mission will be studied in the Sentinel 4&5 context at payload level & at most only accommodation/system level issues considered in the post-EPS study; the IRS will be studied in the frame of post-EPS • Final decision to embark Sentinel-5 on the Post-EPS has to be taken by end of 2009 (or early 2010) together with the definition of the Post-EPS payload complement.

  16. Relation to GMES Sentinels 4&5 – Scientific Activities • The ESA scientific study “Observation Techniques and Mission Concepts for Atmospheric Chemistry” (CAMELOT) is currently running in parallel to the Sentinel -4 and -5 industrial studies with the aim of providing further scientific advice and support to the industrial teams on implementation of critical requirements, orbit trade-offs, and other related issues • Additionally, ESA funding available for an air quality impact studyand a limb-sounding study • Completed MTG studies also relevant • EUMETSAT can run additional science studies to support the process as necessary

  17. Sentinel 4 Mission Objectives Spectral Characteristics Spatial Coverage

  18. Sentinel 4 – Mission Objectives • Sentinel-4 will be focussed on air quality • Main data products  O3, NO2, SO2, HCHO and aerosol optical depth • The specific objective is to support air quality monitoring and forecast over Europe with high revisit time (~1 hour) for the period of time between 2017 and 2032

  19. Sentinel 4 – Spectral Characteristics

  20. Sentinel 4 – Spatial and Temporal Sampling • Repeat cycle < 1 hour with a goal of 0.5 hr • Spatial sampling distance at 45N, 0E <8km • Spatial Coverage (acquisition is only required in the sunlit part of the orbit whenever the Sun Zenith Angle at the observed spatial sample is <92º and the Observation Zenith Angle is <75º)

  21. Conclusions • Atmospheric Chemistry requirements are an essential element in the implementation of future European GEO/LEO missions • ESA & EUMETSAT have taken all necessary steps with the EC to ensure accommodation of GMES S4 on MTG, with full support of ESA & EUMETSAT Delegations • MTG Ground Segment will provide all necessary processing elements and data dissemination capabilities • Same approach has been taken for GMES Sentinel 5

  40. Meteosat Third Generation (MTG) • The UVS mission was studied at instrument level only (not at system level) during pre-Phase A activities but not studied further • Decision endorsed by Council, however, Council also tasked EUM to coordinate with ESA for Implementation of the UVS within GMES, preserving the role of EUM as Operator. This is reflected in the agreed approach for MTG for the ESA C-MIN-08. • Twin satellite configuration also endorsed by EUMETSAT council with the second platform the MTG-S carrying the IRS • With this, a UVS Mission (as Sentinel 4) shall be accommodated within the design margins offered by the MTG Sounding Satellites • The IRS primarily targets meteorological applications but is also expected to provide information on O3 and CO.

  41. Relation to GMES Sentinels 4&5 – Context • Following decisions taken at the 60th EUMETSAT Council (December 2006) • It is recognised that MTG and post-EPS atmospheric chemistry requirements shall be implemented in the context of GMES • "According to current plans Sentinels-4 and -5 will be implemented as additional payloads on the Eumetsat MTG and post-EPS missions, and will be operated by Eumetsat as part of the overall MTG and post-EPS management procedures.“ • Similar decisions taken at ESA PBEO in September 2006 • “ESA-EUMETSAT Working Assumptions on GMES Sentinels-4 and -5” finalised for presentation to EUMETSAT Council and ESA PB-EO by end of 2007, confirmed in 2008 and in use for preparation of C-MIN-08.

  42. Post EPS Atmospheric Chemistry Mission:Approach to Generating Requirements • Generated by a dedicated Application Expert Group (AEG) • Heritage • Integrated Global Atmospheric Chemistry Observations (IGACO) Report from the IGOS Atmospheric Chemistry Theme Partners • ESA commissioned CAPACITY study to define the Geophysical Data Requirements for an Operational Atmospheric Chemistry Monitoring Mission • Requirements specified for satellite observations only • Prioritisation per application remaining aware of observing feasibility
