This award would carry out optical and radar measurements that would be compared with the results of the modeling of the effects of proton precipitation for the region of the equatorward edge of the early evening sector of the auroral oval where protons are known to be a significant energy source. Measurements of the H-alpha and H-beta Doppler profiles would be made with a new high resolution echelle-CCD spectrograph at polar latitudes where the EISCAT incoherent scatter radar would provide concurrent soundings of the proton-auroral ionosphere. The proposed effort is aimed at overcoming several problems that have plagued the proper interpretation of such observations in the past. The use of a high spectral resolution spectrograph would minimize the effect of auroral contamination. The use of the incoherent scatter radar would make possible the acquisition of accurate ionization profiles enabling the accurate determination of the average energy and the energy flux into the region..

该奖项将进行光学和雷达测量，这些测量结果将与在极光椭圆形的傍晚部分的赤道边缘区域的质子沉淀效应模型的结果进行比较，在那里质子被认为是一个重要的能量来源。h - α和h - β多普勒剖面的测量将在极纬地区用新的高分辨率梯队ccd光谱仪进行，EISCAT非相干散射雷达将同时提供质子-极光电离层的探测。所提议的努力旨在克服过去一直困扰着正确解释这类观测结果的几个问题。使用高光谱分辨率摄谱仪将使极光污染的影响降到最低。使用非相干散射雷达可以获得精确的电离剖面，从而精确确定进入该区域的平均能量和能量通量。
