[PEM08-05] WASAVIES: Warning System for Aviation Exposure to Solar Energetic Particles

*Ryuho KATAOKA1, Tatsuhiko SATO2, Yuki KUBO3, Daikou SHIOTA4, Takao KUWABARA5, Seiji YASHIRO6, Hiroshi YASUDA7 (1.NIPR, 2.JAEA, 3.NICT, 4.Nagoya University, 5.Delaware University, 6.CUA, 7.NIRS)

Keywords:solar proton, radiation dose, flares, air shower

Solar energetic particles (SEP) sometimes induce air shower that significantly increase the radiation dose at flight altitudes. In order to inform the situation of such a space radiation hazard to aircrews, a physics-based forward model is developed as WASAVIES (Warning System for Aviation Exposure to SEP) based on focused transport equation and Monte Carlo particle transport simulation code PHITS. WASAVIES gives the fastest and simplest way to predict the time profile of dose rate during ground-level enhancements (GLEs).
