| Research Abstract |
Solar energetic particles (SEPs) sometimes induce powerful air showers that significantly increase the radiation dose at flight altitudes. In order to provide information of such a space radiation hazard to aircrew, a forecast model is developed as WASAVIES (Warning System of Aviation Exposure to SEP), based on the focused transport equation of solar protons and Monte Carlo particle transport simulation of the air shower. WASAVIES gives a simple and fast way to predict the time profile of dose rate during ground-level enhancements (GLEs).
