GCOS: Global Climate Observing System

GCOS ensures access to climate observations, data, and information for individuals, organizations, and agencies addressing climate-related concerns. It follows a three-phase approach driven by users, advocates for open data access, and coordinates with other observing systems.

Presentation Transcript

  1. Global Climate Observing System GCOS Welcome and Update 5th CBS-LC-GCOS & Advisory Group on GSN and GUAN (AGG) 7-9th September 2016 BAS, Cambridge, UK Tim Oakley, GCOS Network Manager

  2. What does GCOS do? The vision of GCOS is that all users have access to the climate observations, data records and information which they require to address pressing climate-related concerns. GCOS users include individuals, national and international organizations, institutions and agencies. The role of GCOS is to work with partners to ensure the sustained provision of reliable physical, chemical and biological observations and data records for the total climate system – across the atmospheric, oceanic and terrestrial domains, including hydrological and carbon cycles and the cryosphere.

  3. Driving the Global Climate Observation Agenda • GCOS follows a 3 phase approach driven by users • 2015 Status Report started the 3rd assessment cycle with a new Implementation Plan due in 2016 for UNFCCC COP 22 (1st cycle: 1995-1998) (2nd cycle: 2003-2004-2010) (3rd cycle: 2015-2016)

  4. GCOS GTOS GOS WHOS GAW GCW

  5. 3 Science Panels • 3 Science Panels for Atmosphere, Land and Oceans: • Capture requirements for users of climate observations. • Identify & review Essential Climate Variables (ECV) and their specification • Review adequacy of networks to measure & exchange data • Give recommendations for the new Implementation Plan • Advocating sustained networks, open data access, and future evolution • Coordinate with other observing systems

  6. GSN – GUAN

  7. GCOS Minimum Requirements • GUAN • Temperature up to 30hPa • Humidity up to tropopause • Wind direction/speed to 30hPa • 1 report - 25 days each month • TEMP message GSN • Monthly means of daily maximum, minimum and mean temperature • Monthly precipitation amounts • If only monthly values, number of days in calculation • Monthly CLIMAT message http://www.wmo.int/pages/prog/gcos/Publications/GCOS-144_en.pdf

  8. CBS Lead centres for GCOS

  9. CBS-LC-GCOS Terms of Reference TERMS OF REFERENCE OF THE CBS LEAD CENTRES FOR GCOS FOR SUBMISSION TO CBS-XIV In support of the Global Framework for Climate Services, especially by improving quality and sustainability of climate data, the Lead Centres for GCOS will: 1. Diagnose problems in the Regional Basic Climatological Networks (RBCNs) and the Antarctic Observing Network (AntON), with the emphasis on the GSN and GUAN, by using the available monitoring reports, such as those produced by the GCOS Monitoring and Analysis CENTRES and major WMO NWP Centres; 2. Liaise with nominated National Focal Points for GCOS and related Climatological Data, and other responsible officials, to rectify identified problems so as to improve data and meta data availability and quality; 3. Coordinate activities with other GCOS CENTRES and/or other WMO CENTRES as appropriate; 4. Report to CBS and GCOS on actions taken, progress achieved, concerns and recommendations on a yearly basis in a time frame that corresponds to planned AOPC and CBS meetings; 5. Assist AOPC in the design of GSN and GUAN and Regions in the design of RBCNs/AntON; 6. Assist the WMO Secretariat in maintaining the list of National Focal Points for GCOS and related Climatological Data.

  10. Key points for this meeting

  11. Review and discuss the monitoring reports since our last meeting in October 2013 (Chile) • Discuss the CBS-LC-GCOS process and the challenges, inview of making recommendations to CBS & GCOS • Engage & contribute to the ‘new’ monitoring tools and future plans, in particular to those being developed through WIGOS • Daily CLIMAT • BUFR • GCOS Implementation Plan (next slide)

  12. 2016 GCOS Implementation Plan
