Serious rice crop damage from a new smelter stack plume at Niihama was recorded in 1893. To avoid its payment of reparation, the smelter was relocated in 1905 to the uninhabited island of Shisakajima, nearly 20 km away. However adverse winds carried the smelter gas pollution over much more wide area. WRF meteorological data at Shisakajima were used to support the historical data, not only for Wind Rose Analysis (WRPlotTM), but also for Consequence Analysis (Phast TM) and/or Aermod View TM). WRF data at Yokohama National University were used to compare with the real meteorological data.
