1Oceanic dispersion model intercomparison: the Fukushima case

Abstract

There are several atsempts to simulate the oceanic dispersion of radionuclides discharged into the ocean after the accident of Fukushima Dai-ichi NPP on Mar 11, 2011. A model intercomparison project launched by a working group established under Japan Science Council, is now trying to compare results from several downscaling dispersion models focusing on Cs137 dispersion for the Fukushima case. Eleven model results from ten groups are participating the project. This presentation introduces the model intercomparison activity and discuss preliminary results of the comparison.nder Japan Science Council, is now trying to compare results from several downscaling dispersion models focusing on Cs137 dispersion for the Fukushima case.
