| 抄録 | Since the NICT's (National Institute of Information and Communications Technology) 256-element imaging riometer was installed at Poker Flat, Alaska, in 1995 in cooperation with the Geophysical Institute of the University of Alaska Fairbanks, it has been recording the high-spatial-resolution Cosmic Noise Absorption (CNA) to study the effect of high-energy electron precipitation on the polar middle atmosphere. We examined how to use the CNA data to estimate the energy distribution of auroral precipitating electrons. In this paper, we describe the method to extract the information of the flux of high-energy precipitating electrons by combining CNA with the optical emissions observed at two wavelengths with the all-sky imager. |
