Abstract

A database for numerical model simulation is prepared based on studies of HiSoF members. This database includes initial and boundary conditions which are 1) amount of flammable materials in 50 m grid within 8 km x 8km area from hypocenter of the A-bomb, 2) times of begin and end of induced fire just after A-bomb in 50 m grid, 3) time dependent heat, water and carbon fluxes in 50 m grid, 4) a wind field in 100 m, 1 km and x km grids within 8 km x 8km area, 50 km x 50 km area and 500 km x 500 km area, respectively. The database also has tables of results of initial survey of radioactivity by many researchers after the A-bomb which can be used as validation data for results of numerical simulations. The database gives reference height of a mushroom cloud and initial distribution of fission products within the mushroom cloud. The database contains rainfall distribution which also can be used as validation data, too.
