1 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 1 “CL Key Climate Data from Satellite Systems” Ivan Petiteville, CEOS WGISS-24, DLR, Oct , 2007

2 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 2 Task Description Define & execute the actions to secure the provision of key data for climate studies and forecasting from satellites to address the needs of the climate community expressed by GCOS (“Systematic Observation Requirements for Satellite-based Products for Climate” )../..

3 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 3 Examples of actions to satisfy GCOS Needs Generation of Fundamental Climate Data Records (FCDRs) and derived products (higher level geophysical products) Update of specifications of FCDRs and derived products by scientific expert groups Comprehensive and routine calibration of satellite instruments Modern distributed data services to access to data and metadata Facilitate the exchange and archiving of all climate-relevant data and products (e.g. data policies) Foster development of emerging operational capabilities for research-based climate variables Exploit the unique value of historical satellite datasets through reprocessing to derive multi-decadal products

4 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 4 History (1/2) Concept endorsed by CEOS Plenary (Nov. 2005) CL Task started in 2006, continued in GEO WP. –CEOS both Lead and Point of Contact Currently, one of the 3 major CEOS activities involving several CEOS Agencies

5 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 5 History (2/2) Regular meetings and telecons –4 major meetings of CEOS experts in 2006 and –Presentation of CEOS Response at UNFCC COP-12 meeting ( Nairobi, Kenya, Nov ) –One of the main topics at each CEOS Plenary (November) and CEOS SIT meetings (twice a year) –Regular teleconferences

6 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 6 Overall Status Identification & execution of a set of 21 top priority actions from the CEOS Response (started in Jan. 2007) Executions of selected actions represent a major effort in the several CEOS agencies CEOS SIT-20 & 21meetings (Jun. & Sep ): status of actions reviewed frequently Teams for execution of the Climate Actions formed (Mar. 2007)

7 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 7 Calendar for 2007 Q highest priority actions in CEOS Response have been identified; - CEOS, in collaboration with GCOS, to establish management and progress monitoring framework Q2-2007Report to CEOS SIT-20 on progress Q4-2007Implement 21 highest priority actions

8 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 8 Activities since Jan 2007 (1/4) Jan-Feb 07: –CEOS, assisted by GCOS, identified 21 top priority actions for implementation by space agencies in 2007 March-April 07: –CEOS Climate Focal points designated by CEOS members and associates to monitor progress within their respective agencies of the actions. 18 Climate Actions Teams created. –Each one animated by a Focal Point from various CEOS Agency. –Each Team is responsible for the executions of several Climate actions.

9 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 9 Activities since Jan 2007 (2/4) March-April 07 (cont’): –Plan announced by NASA and NOAA to restore a key ozone layer climate sensor, the Ozone Mapping and Profiler Suite (OMPS), to the NPOESS programme (launch in 2009). Essential for the CEOS action # A-8. –Coordination between WMO GSICS programme and CEOS Working Group on Cal/Val (both led by NOAA). Objectives: promote the reduction of measurement uncertainty improve the accuracy of climate data records.

10 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 10 Activities since Jan 2007 (3/4) March-April 07 (cont’): –EUMETSAT Workshop (15-16 March). Organised by WMO Participants: CMA, JMA, NOAA, WMO, EUMETSAT, CEOS and GCOS. Objective: refine the concept of a Global Network of Regional Specialized Satellite Centres for Climate Monitoring (RSSC-CM). RSSC-CM concept addresses GCOS requirements for sustained datasets, products and services. For each ECV, one or two RSSC-CM would be responsible to generate consistent high-quality ECV satellite products, to validate them and to make them available in agreed formats with metadata, to conduct research, to contribute to reanalysis, to provide documentation and training. The concept submitted for endorsement by satellite operators on 1 May 2007.

11 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 11 Activities since Jan 2007 (4/4) May-June 07: –CEOS SIT-20 meeting (June 19-20) All specialists meet. Full review of CL related activities. Progress report issued –WMO Workshop (June 21-22) on Re-design and Optimization of the Space-based Global Observing System (GOS). Goal: Review definition of the space-based subsystem of the GOS to better address GCOS requirements for sustained observations of climate variables.

12 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 12 Climate Action Teams (example)

13 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 13 On-going activities (1/2) On-going executions of the 21 actions. WGISS responsible for actions C-18 & C-18 (Kengo is the POC) Collection of monthly reports from Focal Points in progress (not ready for Sep. ADC meeting). CEOS Demo for the GEO Summit being defined –Constellations Visualization DVD (USGS lead) –Climate pamphlet (USGS lead) –Latest CEOS Newsletter (JAXA lead) –Short pamphlet on the “CEOS role for GEOSS” incl. VC (NOAA lead. TBC)

14 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 14 On-going activities (2/2) Extract of one report recently received: –significant progress has been made for climate action A-5: “spectrally resolved absolute radiances”. A CLARREO (Climate Absolute Radiance and Refractivity Observatory) workshop (http://map.nasa.gov/clarreo.html) was sponsored by NASA to review the proposed benchmark measurement missions, which are very important for climate change detection. The WGCV lead expert for this task, Dr. Nigel Fox of NPL, participated in the workshop and presented an update on the status of the TRUTHS mission proposed by NPL. Space agencies should review the proposed benchmark missions to support this CEOS climate action. More info about TRUTHS can be found at:

15 WGISS-24, DLR, Oberpfaffenhofen, Germany, Oct 15-19, 2007 Slide # 15 Issues Execution of some Climate Actions requires a significant amount of resources –Uneven progress of the various Climate Teams. –Some of the 21 actions are likely to be completed only in 2008
