GAW/GAWSIS Data Access
Data Availability: Data are available online for the World Meteorological Organization (WMO) Global Atmosphere Watch ( GAW ) from 5 World Data Centers operated by WMO Members. These data are freely available to the scientific community. In some cases, the WDCs provide additional products including data analyses, maps of data distributions, and data summaries. The functions of the World Data Centers are to collect and archive data on the background chemical composition and related physical characteristics of the atmosphere from all parts of the globe, to manage the resulting data base, to distribute the collection data and products and information derived from them, and to provide services to the users, in collaboration with the station and laboratories submitting the data, other GAW and non-GAW centers and the WMO. GAW Station Information data are available online through the GAW Station Information System (GAWSIS). GAWSIS was adopted by WMO as the official information system of GAW. |

Access the Databases
- World Data Centre for Greenhouse Gases (WDCGG) (Japan Meteorological Agency (JMA), Tokyo, Japan)
- Data for greenhouse (CO2, CH4, CFCs, N2O, etc.) and related (CO, NOX, SO2, VOC, etc.) gases and surface ozone in the atmosphere and ocean
- Access WDCGG data
- 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.
- Access WOUDC data
- 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) from 1964 to 1993.
- Access WRDC data
- 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

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.
