Summary of activities of GCOS/WCRP Atmospheric Observation Panel for Climate Adrian Simmons, AOPC Chair • AOPC met 27-30 April 2009 − Will meet 26-30 April 2010 (with SPARC representation) − Tends to cover quite a lot of the same ground as WOAP • Significant involvement in: − Progress Report on GCOS Implementation (Published Aug 2009) − Update of GCOS Implementation Plan (Workshop 2-5 Feb 2009) − World Climate Conference – 3 (31 Aug - 4 Sept 2009) 1 Guidelines for generation of datasets and products • AOPC has led the development of a set of GCOS guidelines on generation of datasets and products [Sessions 8 and 11] − Original request from dataset developers was for GCOS recognition of dataset − Developed 12 guidelines that can serve for self-certification • Independent requests have been made for dataset review mechanism − Pre- or post-production review? − By whom? − GCOS SC identified WOAP as forum to consider this • WMO Commission for Climatology is to develop strategy for implementing quality management in climatology − Including dataset management and product generation − Has set up Expert Group 2 AOPC: • noted that datasets from several new reanalyses would soon be available, and recommended study groups be formed to inter-compare them, to be discussed further by the Chairs of AOPC and WOAP with a view to these groups providing reports to the next WCRP international conference on reanalysis [Session 7 of this meeting] 3 Atmospheric Chemistry • AOPC urged GAW secretariat to strengthen support for − common coding standards − near-real-time data supply − improved data management − network integration for observations of atmospheric composition • Stronger emphasis on atmospheric composition in updated version of the GCOS Implementation Plan − Identified importance of observations of precursor species for ozone and aerosols in ECV table − Extensive revision of Actions and supporting text on composition • Other initiatives − GEO communities of practice for carbon and air quality − Measurement standards (WMO-BIPM workshop, 30 March – 1 April) 4 General topics, many to be covered later in this meeting • In-situ data − Specific network (GSN, GUAN, BSRN, comprehensive) issues − Establishment of GRUAN continues to receive special attention − [Session 9, Session 11] • Satellite data − Reports from CEOS, CGMS and some individual agencies − GSICS, SCOPE-CM, ESA-CCI [Session 5, Session 11] • Data products − GPCC [Session 8] and reanalysis [Session 7] • Interactions – With OOPC, TOPC, CCl, GEO, WCDMP, GFCS planning, … • Review items – Palaeo climatology, urban climatology, … 5
