Environmental Emergency Response

Role of the WMO Secretariat in case of a Nuclear Accident

The WMO Secretariat operates an Office for Emergency Response to Nuclear Accidents (ERNA) under the direction of the Director for Basic Systems. It has computerised access to the GTS and dedicated fax/voice communication and is monitored by a staff member during office hours.

The responsibilities of the WMO ERNA Office include:

  • Receiving and authenticating/verifying incoming messages, relaying information to Geneva- based UN organisations (subject to bilateral arrangements)

  • Providing relevant information to WMO Members' NMHSs on request and making available information provided by the Accident State or other sources to dedicated WMO specialised centres of the GDPS

  • Participating in test exercises

Provision of Atmospheric Transport Model products

WMO, in collaboration with IAEA, has developed and implemented in four WMO regions, regional and global arrangements, involving two WMO designated Regional Specialized Meteorological Centres for each of the six WMO regions, for the provision of transport model products for environmental emergency response in case of an accident situation.

The eight currently designated centres in Bracknell, Toulouse (for Europe), Washington, Montreal (for North and Central America), Beijing, Obninsk, Tokyo (for Asia) and Melbourne (for South West Pacific) use sophisticated atmospheric simulation models to provide information on actual and anticipated dispersion/disposition of pollutants in the atmosphere.

National Meteorological Centers using the products provide interfaces and services to national authorities concerned.
