Evaluation of Meteorological Analyses for the Radionuclide Dispersion and Deposition from the Fukushima Daiichi Nuclear Power Plant Accident

The WMO organized a small Task Team (TT) in 2011 to respond to a request from the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) to assist them with determining the meteorological aspects of a dose assessment of the radiological releases from the Fukushima Daiichi nuclear power plant accident.

The TT’s primary mission was to examine how using meteorological analyses and
introducing additional meteorological observational data might improve atmospheric transport, dispersion and deposition calculations, critical components in dose computation. Although the TT would not be doing dose computations directly for the UNSCEAR assessment, the members agreed that the best way to evaluate the suitability of the various meteorological analyses for this purpose was to use the meteorological data in Atmospheric Transport Dispersion and Deposition Models (ATDM)
and compare the model predictions with radiological monitoring data.

The TT completed its work in December 2012. Please see the Report on the Meting of the WMO Task Team on Meteorological Analyses for Fukushima Daiichi Nuclear Power Plant Accident and Annex III.

Annex III is also available as WMO-No. 1120, published in 2013.
