CEDAR: Ionospheric Auroral Disturbances in Proton Aurora

这一奖项将进行光学和雷达测量，并将其与对极光椭圆形早晚扇区赤道向边缘区域质子降水影响的模拟结果进行比较，在该区域，质子被认为是一种重要的能源。将在极地纬度使用一台新的高分辨率梯形-电荷耦合器件光谱仪测量H-α和H-β多普勒分布，在那里EISCAT非相干散射雷达将提供质子-极光电离层的同时探测。拟议的努力旨在克服过去困扰对这类意见的适当解释的几个问题。使用高光谱分辨率的光谱仪将最大限度地减少极光污染的影响。非相干散射雷达的使用将使获取准确的电离剖面成为可能，从而能够准确地确定进入该区域的平均能量和能量通量。

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..
