Outline of Final Research Achievements

We investigate mechanisms to cause modulation of the pulsating aurora based on high-speed camera (EMCCD/s-CMOS) and ground-based loop antenna observations at Poker Flat Research Range at Alaska, US and Athabasca, Canada. The observation data showed that the main modulation and internal modulation of the pulsating aurora are caused by chorus bursts and rising tone elements, respectively. Moreover, we investigate comparative study between the precipitating electrons measured by low-altitude satellites and computer simulations. As a result, we identify relationship between energy spectrum of precipitating electrons and frequency spectrum of chorus waves.
