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
*Currently, radiation dose rates are updated by 1 day interval.
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)
World dose rate map adopted to the format used in the ICAO advisory.
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
