Other observational data received over the Global Telecommunications System (GTS) - e.g. ship, buoy and aircraft reports:

The WMO Information System (WIS) is the mechanism by which National Meteorological and Hydrological Services around the world undertake weather and climate-related data exchange and management.

MetService undertakes this function for New Zealand, with state-of-the-art  telecommunication facilities providing connections to countries across the South Pacific,  and to major global weather centres such as the Australian Bureau of Meteorology, the Japan Meteorological Agency, the United States National Weather Service, and the United Kingdom’s Met Office. 

Information about the data exchanged on the WIS is held in a number of online catalogues containing a wide range of meteorological data and products. If you’d like to learn more about the WMO Information System, please email data.manager@metservice.com
