The Expert Team for Atmospheric Composition Data Management
The WMO Expert Team on Atmospheric Composition Data Management, originally the WMO/CAS OPAG-EPAC Expert Team on World Data Centres (ET-WDC) was formally established in 2006 by CAS-XIV [1] but has a history of activities that dates back to the 1990s. The activities are overseen by the Research Board and The Environmental Pollution and Atmospheric Chemistry Scientific Steering Committee (EPAC-SSC).
The core activities of this Expert Team include:
- Documenting issues with and coordinating the development and implementation of common data and metadata standards within GAW, in alignment with WIS/WIGOS, and assisting Contributing Networks with utilizing the WIGOS metadata standard
- Advising the SAGs, WMO expert teams and partners, and GAW initiatives' steering committees on harmonizing data management
- Enabling F.A.I.R (findable, accessible, interoperable, re-usable) data principles in support of plug and play capabilities (data formats and application program interfaces, APIs) of GAW data
- Collecting and providing information on NRT (within 3 hours of observation for real-time, within 72 hours of observation for near-real-time) data transmission to station operators
- Facilitating the timely submission of quality-controlled data for long-term archival in the respective GAW World Data Centres (WDCs)
- Providing comprehensive and up-to-date guidance on the data and metadata submission processes, revision and re-submission, including consideration of data-policy, licenses, provenance, data quality and consistency between the data and the metadata
- Monitoring the data submission to the thematic WMO WDCs, and providing consolidated annual statistics on data submission, distribution, and use of EPAC SSC
- documenting and identifying issues and proposing solutions in support of further development of GAWSIS as an integral component of OSCAR/Surface
- Guiding GAW WDCs on implementing WMO data policies, in providing use groups with free and open access to all data, complemented with access to innovative and mature data products, together with tools for QA, data analysis and research, following WIGOS policies in particular with regards to metadata documentation
- Guiding GAW WDCs and archives of Contributing Data Centres on implementing new technologies to elevate information management within GAW, as well as Contributing Networks, in-line with the evolution of WIS/WIGOS
