Outline of Final Research Achievements |
We aim to reveal the elevation distribution of auroral polarization along the magnetic meridian by using a newly developed wide field auroral polarization imaging spectrometer. IWe also developed a calibration light system to validate apparent polarization caused by atmospheric scattering and instrument. We installed the instrument at Pokar Flat Research Range, Alaska in November of 2015 and took many calibration data for various field-of-views. Using the calibration data, we evaluated polarization degree with an accuracy better than 0.2 percent. We obtained the linear polarization degree of 630 nm aurora as 1.6 +/- 0.9 percent. For most cases, polarization degree showed a tendency that maximized at the low elevation angle, and decreases as the elevation angle increases. In addition, we contributed the international collaboration with Norway by coordinated EISCAT-radar and optical observations. 4 master students and 2 undergraduate students were graduated based on this study.
