Welcome to WASAVIES (WArning System for AVIation Exposure to Solar energetic particle) homepage. It calculates the radiation dose rates due to cosmic-ray exposure anywhere in the atmosphere based on the cosmic-ray observations at the ground level and geostationary orbit. The data are updated at intervals of 5 min and 1 day during solar storm and quiet periods, respectively.
No radiation exposure event
At present, daily dose maps are available.
Current radiation dose rates at the altitude of 12 km (39,400 feet)
WASAVIES provides the following data
World dose rate map at the altitudes between 0 and 100 km (328,000 feet)
Dose rate map for selected 7 flight routes
Time dependence of the highest dose rates in the world at certain altitudes at interval of 5 min
Time dependence of the count rates of neutron monitors used in WASAVIES at interval of 5 min
Time dependence of proton flux (E>100MeV) measured by geostationary satellite GOES at interval of 5 min
