• GASES - World Data Centre for Greenhouse Gases (WDCGG) (Japan Meteorological Agency (JMA), Tokyo, Japan). Data for greenhouse (CO₂, CH₄, CFCs, N₂O, etc.) and related (CO, NO_X, SO₂, VOC, etc.) gases and surface ozone in the atmosphere and ocean.
  • Access WDCGG data

• OZONE/Ultraviolet Radiation (UV) - World Ozone and UV Data Centre (WOUDC) Meteorological Service of Canada (MSC), Downsview, Canada. The ozone data archive contains: Lidar vertical profiles, Ozonesonde vertical profiles, Total column ozone (Daily and Monthly values), Surface ozone (Daily summaries), and Umkehr N-value and C-Umkehr vertical profiles. The UV data archive contains the following data categories: Broad-band, Multi-band and Spectral.

• RADIATION - World Radiation Data Centre (WRDC) (Russian Federal Service for Hydrometeorology and Environmental Monitoring, A.I. Voeikow Main Geophysical Observatory, St Petersburg, Russia). WRDC archive contains data on: Global solar radiation, Diffuse solar radiation, Downward atmospheric radiation, Sunshine duration, Direct solar radiation (hourly and instantaneous), Net total radiation, Net terrestrial surface radiation (upward), Terrestrial surface radiation, Reflected solar radiation, Spectral radiation components (instantaneous fluxes).

• AEROSOLS - World Data Centre for Aerosols (WDCA) Institute for Environment and Sustainability (IES), Ispra, Italy. The WDCA objective is to determine the spatio-temporal distribution of aerosol properties related to climate forcing and air quality up to multi-decadal time scales.
• Access WDCA data


• REMOTE SENSING OF THE ATMOSPHERE - The World Cata Center for Remote Sensing of the Atmorsphere (WDC-RSAT) WDC-RSAT is supporting the development of user oriented value added products. The current WDC-RSAT data holding contains data and information on trace gases, aerosols, clouds, land and sea surface parameters, and solar radiation. This is achieved either by giving access to data stored at the data center or by acting as a portal that contains links to other data providers.
• Access WDC-RSAT data

GAW Station Information System (GAWSIS)

GAWSIS is an initiative by QA/SAC Switzerland in collaboration with the WMO Secretariat, the GAW World Data Centers and other GAW representatives to improve the management of information about the GAW network of ground-based stations. GAWSIS was adopted by WMO as the official information system of GAW. GAWSIS provides information on sites, measurement programs and data, and contacts.

Contributing Stations

Contributing stations belong to other organizations or international programmes such as the NDACC, the EMEP, the BSRN or the SHADOZ networks. Through mutual agreements, these contributing organizations are under the GAW umbrella of stations. Some of these stations have dual affiliations with GAW, having also the status of Global or Regional GAW station.

• NDACC > Network for the Detection of Atmospheric Composition Change
• EMEP > European Monitoring and Evaluation Programme Data
• BSRN > Baseline Surface Radiation Network
• SHADOZ > Southern Hemisphere Additional Ozonesondes
