Sondrestrom ISR/POLAR UVI Global Conductance Model

研究人员将在极地卫星紫外线成像仪和Sondrestrom非相干散射雷达之间的一系列多年、多季节合作实验的基础上，创建一个太阳风参数全球极光电导模型。极光电导是一个严重不足的参数，对于更广泛地了解磁层施加的电流、对流势和高纬度电离层中的能量沉积的结构至关重要。其目的是将非相干散射雷达电导测量与来自紫外线图像的电导估计合并在一个单一模型中，该模型利用了这两种技术提供的互补信息。全球电离层的现代电动力学模型要求准确说明极光能量沉积及其在高纬度的相关电导。这项研究通过创建一个与太阳风的特性相关联的模型来解决当前电导模型的弱点。这项研究的最终输出将是太阳风参数化的全球电导图，其空间分辨率可能达到最佳水平。

The investigators will create a solar wind parameterized global auroral conductance model based on a series of multi-year, multi-season, collaborative experiments between the POLAR satellite ultraviolet imager and the Sondrestrom incoherent scatter radar. Auroral conductance is a critically underdetermined parameter that is central to a broader understanding of the structure of magnetospherically imposed currents, convection potential, and energy deposition in the high latitude ionosphere. The aim is to merge incoherent scatter radar conductance measurements with conductance estimates from ultraviolet images in a single model that takes advantage of the complementary information available from the two techniques. Modern electrodynamics models of the global ionosphere require an accurate specification of auroral energy deposition and the associated electrical conductance at high latitudes. This study addresses the weakness of current conductance models by creating a model tied to properties of the solar wind. The final output of the study will be solar wind parameterized global conductance maps at the best possible spatial resolution.
