Data for: Refinement of Source Term and Atmospheric Dispersion Simulations of Radionuclides during the Fukushima Daiichi Nuclear Power Station Accident
Description
The database was generated by the atmospheric dispersion simulations using the optimized source term of the Fukushima Daiichi Nuclear Power Station accident. It consists of 960 data files in the NetCDF format, including horizontal 2-D distributions of air concentration in the surface layer and surface deposition (total deposition, dry deposition, wet deposition, and fog deposition) of radionuclides (total 131I, 131I chemical species (I2, CH3I, and particulate iodine), 134Cs, 137Cs, and 132Te), horizontal wind components, rain intensity, and ground elevation in two calculation domains (local: 190 × 190 km2 area with a 1 km resolution, regional: 570 × 570 km2 area with a 3 km resolution) for hourly output times from 16:00 UTC on March 11 (01:00 JST on March 12) to 15:00 UTC on March 31 (00:00 JST on April 1), 2011 (480 output times).
