| 内容記述 | Observations by rocket-borne spectrometers of the high-latitude dayside aurora above Cape Perry, N.W.T. are reported. UV spectra of optical emissions produced by ambient precipitating particles are obtained in the 530-1500 A region, over a range of spectrometer line-of-sight orientations, from 100 km to the rocket apogee of 452 km. The spectrum below 1500 A is dominated by transitions from neutral and singly ionized atomic oxygen. N I, N II, and N2 emissions, which are prominent in day airglow and nighttime auroral spectra measured by the same instrumentation, are very weak, indicating energy from the dayside auroral particles is transferred to the atmosphere above most of the N2. Relative line strengths of O I and O II transitions in the high-latitude dayside aurora differ in comparison with either airglow or nighttime auroral observations. |
