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 (e-copy), published in 2013.
