The WMO Vision for Global Observing Systems in 2025 John Eyre, ET-EGOS Chair GCOS-WMO Workshop, Geneva, January 2011

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Vision for Global Observing Systems in 2025 WMO-CGMS response to GCOS Satellite Supplement in 2006 : the space-based GOS does not address all ECVs –ERB, Ozone, GHG, aerosols, Global precipitation –Sea level and sea state, Ocean colour –Vegetation, Glaciers and ice sheets Recommended to redefine its scope to encompass climate one main objective, in addition to weather This triggered a review of the GOS: both space AND surface components

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Vision for Global Observing Systems in 2025 Contents: –General themes and issues Response to user needs Integration Expansion Automation Consistency and homogeneity –Surface-based component –Space-based component Approved by WMO EC, June 2009

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Space-based component (1) Operational geostationary satellites – at least 6 – each with: Infra-red/visible multi-spectral imager Infra-red hyper-spectral sounder Lightning imager Operational polar-orbiting sun-synchronous satellites - in 3 orbital planes – each with: Infra-red/visible multi-spectral imager Microwave sounder Infra-red hyper-spectral sounder

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Polar-orbiting satellites (sun-synchronous) Recommended baseline with in- orbit redundancy

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Geo-stationary satellites km6370 km … are a long way away!

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Space-based component (2) Additional operational missions in appropriate orbits: Microwave imagers – precipitation, sea-ice, humidity, cloud … Scatterometers – sea-surface wind, soil moisture Radio occultation constellation – temperature/humidity profiles Altimeter constellation – sea-surface height, sea level Infra-red dual-view imager – sea surface temperature Advanced visible/NIR imagers – ocean colour, vegetation Visible/infra-red imager constellation – land-surface Precipitation radars Broad-band visible/IR radiometers – radiation budget Atmospheric composition monitoring instruments Synthetic aperture radar – waves, …

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Space-based component (3) Operational pathfinders and technology demonstrators: Doppler wind lidar – wind profiles Low-frequency microwave radiometer – salinity, soil moisture Microwave imager/sounder on geos - precipitation Advanced imagers on geos Imagers on high-inclination, elliptical orbits – High-latitude winds, volcanoes, fires, sea-ice Gravimetric sensors – water: lakes, rivers, ground Polar and geo platforms/instruments for space weather for solar imagery, particle detection, electron density

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 Applications Operational meteorology –NWP –Nowcasting Climate monitoring Operational oceanography – open ocean, coastal Hydrology Atmospheric composition –Ozone layer monitoring, greenhouse gas monitoring, air quality monitoring Space weather

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 The new EGOS-IP (1) Implementation Plan for the Evolution of Global Observing Systems Responds to: The new Vision for Global Observing Systems in 2025 Outputs of Rolling Review of Requirements (RRR) process: –User requirements –Statements of Guidance (gap analyses) –… for all application areas For climate monitoring: –GCOS URs, GCOS gap analysis and the new GCOS-IP

WMO OMM GCOS-WMO Workshop, Geneva, January 2011 The new EGOS-IP (2) Original EGOS-IP approved by CBS in 2005 Annual updates - reviews of progress against actions Initial draft ready for review, January 2011 Input from stakeholders in CBS and beyond, Aiming for approval by CBS in 2012 For space-based climate aspects, will be aligned with the future Architecture
