Sondrestrom ISR/POLAR UVI Global Conductance Model

研究人员将根据POLAR卫星紫外成像仪和Sondrestrom非相干散射雷达之间的一系列多年、多季合作实验，创建一个太阳风参数化全球极光电导模型。 极光电导是一个严重欠定的参数，是中央的磁层强加的电流，对流势，在高纬度电离层和能量沉积的结构更广泛的理解。 其目的是合并非相干散射雷达电导测量电导估计紫外线图像在一个单一的模型，利用互补的信息，从这两种技术。 全球电离层的现代电动力学模型需要精确说明高纬度极光能量沉积和相关电导。 这项研究通过建立一个与太阳风特性相关的模型来解决电流电导模型的弱点。 这项研究的最后成果将是以尽可能高的空间分辨率绘制的太阳风参数化全球电导图。

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.
