Monitoring atmospheric composition & climate
Release of radioactive material in Japan

MACC is developing services to support institutions that are providing advice and warnings related to atmospheric composition. For the current precarious situation with the Fukushima nuclear power plant in Japan, MACC will not put any plume simulations on the public MACC web site as we have done in the past, for instance for the Icelandic volcanic eruption. There are dedicated advisory centres that are responsible for providing this kind of information (see also information on WMO web site); MACC will support these centres, where possible, but not interfere with them by providing its own plume forecasts. There is currently very little information about the amount and time of release of any radioactive material. Especially the timing plays a crucial role in the development of a plume. Therefore the task of providing the most accurate plume forecasts should be left to the specialized institutions.

In Europe the Central Institute for Meteorology and Geodynamics in Austria has been asked by WMO to support the International Atomic Energy Agency with plume calculations. More information can be found on their web site.

MACC will keep following the developments to see where it can support the dedicated centres in the process of providing useful information to the general public.
