Abstract | In this presentation, we discuss the Traveling ionospheric disturbances observed over New Zealand, Australia, and South America that were caused by the multiple explosions of the Tonga volcano (20° S; 175° W) on January 15, 2015, the first one of which occurred at ~4:15 UT. To observe the ionospheric effects at these locations, approximately 1000 GNSS receivers were used to calculate the detrended total electronic content (dTEC). Approximately 1.0 - 1.5 hour after the first explosion, traveling ionospheric disturbances (TIDs) were observed over New Zealand with a horizontal wavelength (λ_H) of 1300-1525 km, horizontal phase velocity (C_H) of 551-635 m/s, period (τ) of 39-40 min, and azimuth (?) (α) of 210-215°. On the other hand, in Australia, TIDs were observed 3 hours after the explosion with λ_H, C_H, τ, and α of 861 km, 478 m/s, 30 min, and 266°, respectively. Finally, in South America, 8 hours after the explosion, we observed TIDs with the following characteristics: λ_H between 348 and 1174 km, C_H of 294 - 515 m/s, τ of 19 - 36 min., and α of 32°. Between 18:00 UT and 19:00 UT, we also observed TIDs over South America with λ_H of 330-505 km, C_H of 275 - 350 m/s, τ of 20 - 24 min., and α of 32-139°. We then discuss using the Model for gravity wavE SOurce, Ray trAcing and reConstruction (MESORAC) to calculate the primary GWs and the HIAMCM (HI Altitude Mechanistic general Circulation Model) model to determine the secondary GWs in the thermosphere created by these explosions. Via comparison with these model results, we show that it is the secondary GWs which propagate over New Zealand, Australia, and South America. |
