| Outline of Final Research Achievements |
We have installed 3 GNSS receivers at EISCAT radar site in Tromsoe, Norway and developed a system to measure phase and amplitude of the received radio waves at dual frequencies. With this system, we have observed fluctuations of the radio waves (scintillation) and compared them with aurora observed with optical instrument. Using more than 800 GNSS receivers in Europe, we have calculated total electron content and revealed statistical features of traveling ionospheric disturbances.
