PROGRAMME NAME

WMO/CTBTO Monitoring Network
WMO/CTBTO (Comprehensive Nuclear-Test Ban Treaty Organization)

URL/ Website http://www.ctbto.org
Description

The Comprehensive Nuclear Test-ban Treaty Organisation (CTBTO) has concluded a formal working arrangement with the WMO, which, inter alia, includes the provision to the World Weather Watch/Global Observing System (WWW-GOS) of meteorological measurements generated by the global radionuclide monitoring station network operated by the CTBTO. The network, which will eventually comprise about 80 stations, is being implemented.

Agenda 21 - Areas of particular focus or interest Atmosphere
Regions Worldwide
Data collection, Observation, Monitoring

The meteorological data are extracted in real-time from a CTBTO-specific data stream by the Canadian Meteorological Centre (CMC), Montreal. The data are encoded in the WMO code SYNOP/MOBILE and routinely exchanged on the World Weather Watch/Global Telecommunication System (WWW-GTS). A station report includes air pressure, temperature, wind direction and speed.
