Comprehensive Overview of ECV Data Sourcing and Fact Sheet Creation Process
Detailed insights into the ECV data sourcing procedures, criteria for selection, and the development of fact sheets, as outlined by the GCOS Secretariat and WMO representative Valentin Aich. The content covers requirements tables, product definitions, data sources compilation steps, and the importance of ECV stewardship. It highlights the criteria for global coverage, accessibility, quality control, and metadata availability, emphasizing the vital role of GCOS Science Panel Experts in the process.

Group work: 1. Requirements table- Rational/Context 2. Product definitions 3. Data sources 4. ECV factsheets 5. ECV Stewards GCOS Secretariat, WMO Valentin Aich
OSCAR definitions Part of the fact sheets If definition in OSCAR exists, are we happy with it?
Data sources: Steps taken 1. Draft list based on data sets listed in the Global Observing Systems Information Center (GOSIC) 2. Agree on criteria 3. Sent to GCOS ECV-Stewards of the three GCOS scientific panels for review 4. Publish/share list on website and update/maintain list
ECV data sources The vision of GCOS is for all users to have access to the climate observations, data records and information they need to address pressing climate-related concerns.[ ] Request from different sides GEO establishing ECV data interface WMO-context: 1. WMO Workshop on Information Management October 2017
Criteria 1. Global in coverage 2. Free and open access 3. Quality controlled with documentation 4. Metadata available 5. Considered by the appropriate GCOS Science Panel Experts
Data sources List published as living document ECV Steward to judge suggestions for additional sources The list does not claim to be complete. It should provide main data sources, which offer global data for the related ECV product
Factsheets GCOS Steering Committee Meeting 2017Report: It was decided to produce a fact sheet for each ECV. The fact sheet will be a single page including a definition, a description, a picture, the requirements with an explanatory text. Existing fact sheets for Essential Ocean Variables (EOVs) might serve as examples or templates for other variables.
Draft facts sheets 1. Include basic facts about ECV 2. Short text why ECV is Essential for climate 3. Definitions 4. Requirements 5. Data sources 6. Figure of illustrative trend of ECV
Tasks 1. Include basic facts about ECV 2. Short text why ECV is Essential for climate-> Review 3. Definitions -> Agree 4. Requirements 5. Data sources-> Check 6. Figure of illustrative trend of ECV- Suggest
