The primary objectives of the GAW QA/QC system are to ensure that the data in the WDCs are consistent, of known and adequate quality , supported by comprehensive metadata, and sufficiently complete to describe global atmospheric states with respect to spatial and temporal distribution. AREP GAW GAW and GCOS WMO/GAW Global atmospheric CO 2 CH 4 and global N 2O monitoring networks are “comprehensive” networks and the GAW Dobson, Brewer and ozone sonde networks are “baseline” networks of GCOS. Similar status is being sought for aerosol networks. AREP GAW Observations are also needed in NRT Criteria different from data for climate services AREP GAW GAW WIS WIGOS Pilot Project Improvement of Dissemination of Ozone and Aerosol observations in NRT - Rationale • Availability of ozone and aerosol data would allow ingestion into atmospheric models in support of improved weather forecasts, surface UV and air quality. • WMO ozone bulletins need ozone data in NRT • Large, integrating projects, such as GEMS and MACC need ozone and aerosol data in NRT for model validation • Delivery of NRT data can help to detect problems at stations at an early stage. AREP GAW Provision of data Data analysis and distribution GAWSIS, WDCs, Experts, Stations Assessments Need observations, research and collaboration Current ones (WMO and …): • Ozone assessment (UNEP) • Precipitation assessment (SAG, GESAMP) • Black carbon and Ozone assessment (UNEP) • Megacity assessment (IGAC) Data and Data quality relevant!
