Current CCl status report to ICG-WIGOS

1. Current CCl status report to ICG-WIGOS Chenghu Sun William Wright 22 Jan 2016

2. Activities of Relevance to WIGOS • CCl (and OPACE 1) structure for 2014-18 Intersessional Period is at http://www.wmo.int/pages/prog/wcp/ccl/cclstructure.php Ongoing activities - • Climate Data Rescue and Climate Data Management Systems • IPET-CDMP • Rapporteurs on observational issues • Task Teams/rapporteurs on: - statement of guidance for climate; - voluntary observing networks; - reference climate stations

3. Climate Data Rescue • ET-DARE continuing as an ongoing activity. Essential to find, secure and digitise/image historical climate records; • ET-DARE includes leaders of major non-WMO players in data rescue/recovery (ACRE, IEDRO) • Prototype I-DARE portal was developed - white paper and specification produced; - catalogue of undigitised data holdings - side event at CG XVII (prototype demo) Challenge: Sustaining the portal

4. Climate Data Management Systems • CDMS specifications document published (WMO TD no 1131) • Progress on climate schema for the WMO Core Metadata profile • Open CDMS Roadmap for Open CDMS developed • Challenges: - comms infrastructure in D & LDC; - training needed in climate data management;

5. IPET-CDMP(Climate Data Modernisation Program) • Established a cross-program ET consisting of several CCl reps and also representatives from CBS, JCOMM, GCOS, WCRP • Emphasis on climate-specific aspects (relevant CDMS specs; better regulation of practices; • A concept paper has been drafted • Close collaboration with WIGOS DM initiative on cross-program issues. • Provisional planning for back to back meetings of WIGOS team and IPET-CDMP in 1st quarter 2015-16 Challenges: • Large undertaking that may take many years; • Ensuring effective ongoing collaboration.

6. GDMFC Manual Outline • 1.Data Archival and Exchange • Guidelines for sustainable archiving procedures; • A standardised cross programme approach to archival and exchange. • 2.Sources of data • Ensuring new observation technologies such as AWS produce data in a way that meets climate requirements; • Harnessing remote-sensed data for climate purposes • Guidance on managing data from a range of data providers • Climate/weather/water/marine observations • Model data • Data sourced from organizations other than an NMHS • Environmental, biological, Socio-economic and hazards data • 3.Data Management: • Standardisation and update for definitions, terminologies and vocabularies; • Data ingest and extraction; • Data rescue, preservation and stewardship; • Data quality control, assessment and improvement, including an end-to-end approach to quality management; • Management of climate and discovery metadata; • Homogenization of time-series; • Handling gaps in data; • Techniques for aggregation and disaggregation of data; • Developing retention policies for data and metadata; • Identify data sets required to support climate services; • Combining data of differing uncertainty

7. 4.Data Management Architecture. The relative roles of: • Global Climate Data Centres • Regional Climate Centres (Data Management nodes) • National Meteorological and Hydrological Services (climatology entities) • 5.Data Management governance • Data management planning and policies • Technical regulations • 6.Capacity building platform and infrastructure • Core competencies and responsibilities (of individuals) • Provision of assistance and advice to Members • Training strategies and curriculum • 7.Quality Management System • Managing changes to observing systems and processes; • Recording and documenting processes including calibration algorithms; • Publication of datasets • Data policy and licensing • Authoritative versions of data such as Digital Object Identifiers (DOI) • Certification of data sets. Define standard if it does not exist.

8. Rapporteurs on Observational Standards & Practices • A group of experts to address climate observation issues and engage with relevant groups in other domains, e.g. GCW. • Experts to attend relevant meetings (IPET-OSDE, Spice, etc). • Address relevant ad hoc tasks or initiatives such as centennial stations, quality control guidelines, etc • Draft of reference network guidelines completed and being reviewed; • Cg presentation about how to establish Voluntary Observing networks

9. OBSERVATIONS – Rapporteurs, etc • Complete reference networks guidance. • Input and expertise to be provided w.r.t. Centennial stations, RBON, network planning etc. • Continue engagement in climate-related observing systems in marine, global cryospheric watch, etc • Greater engagement with metrology community to ensure forthcoming program meets climate needs • Progress guidance on establishing voluntary observing networks; • Expansion of CocCoRaHS precipitation network to Bahamas and beyond • Re-focus TT-SOGCON (next slide)

10. Other relevant task teams TT-SOGCON Rapporteurs on Voluntary Observing Networks Collaborations with WIGOS on Voluntary observing networks Guidelines on implementing and maintaining Effective Observing networks for climate services
