Plain Language Summary: An intercomparison study of four aerosol wet deposition schemes on the model was performed to simulate particulate Cs-137 in the emission scenario of the March 2011 accident at the Fukushima Dai-ichi Nuclear Power Plant. Additional tests were also conducted on the sensitivity of aerosol tuning parameters and the impact of aerosol-cloud interactions. It is found that a proper set of rainout parameterizations and tunings are as important as the accurate meteorological fields, i.e., wind and water vapor, in determining the reproducibility of Cs-137 aerosol simulations.
