CONTRIBUTING ORGANISATIONS

The principal aims of the GUAN are to ensure a relatively homogeneous distribution of upper air stations that meet specific record length and homogeneity requirements outlined by GCOS, and make available their current and historical data for climate research.

The World Meteorological Organisation (WMO) and the Global Climate Observing System (GCOS) act on information provided by the monitoring and analysis centres to feedback to contributing members and encourage them to provide station data to the GUAN.

The Met Office, Hadley Centre of the UK develop upper air datasets for use in climate research.

The National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC) of the USA, update and quality control daily upper air data and historical metadata as part of the Integrated Global Radiosonde Arhive (IGRA). The World Data Center for Meterology (WDC) holds the GUAN archive.

The European Centre for Medium Range Weather Forecasts monitor the receipt and quality of daily TEMP data.
