[PEM16-P11] Estimation of electron density distribution of strong Es using VOR, AIS and Ionosonde and its application to the VHF interference model of long-distance propagation wave
Yamagawa (31.20N, 130.62E) and Okinawa (26.68N, 128.15E) observed Es in the East China Sea, Okinawa and around the Kyushu south where the distance with ionosonde will be about 400 km in the range at 10-JST time 15:00 on June 15, 2014. It could be confirmed that Es has moved to about 330 deg direction by high 108 km and speed about 70 m/s. This Es showed that the electron density the strong Es territory where 1.0 x 10^13 el/m^3 appeared, and which can put electron density in Okinawa ionosonde is parallel with strong Es where 9.2 x 10^12 el/m^3 mostly in the Okinawa south and around the east around 10:10-11:30 in AIS. In case of this time’s Es, it was assumed that there was a possibility beyond the VOR reception electric power-98dBm that intervention with VOR and GBAS - VDB is worried about when Es propagation model of ITU - R was applied. An analysis sample by this way will be indicated in the lecture, and I report on a relation between the distribution of the electron density, the feature of the transport property and intervention occurrence of strong Es conversantly.
