Abstract - The World Meteorological Organization (WMO) organized a small Task Team (TT) 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 TTs 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.
