Space Weather: Factors Controlling Ionospheric Outflow

该项目将分析快速极光快照小型探测器（Fast）卫星的数据，以及ACE和wind航天器的太阳风数据。它将研究控制离子从极地电离层流出的过程。特别地，它将决定大尺度焦耳加热、阿尔芬波加热和电子沉淀加热的相对重要性。这项工作将产生一套经验标度定律，可用于参数化离子流出率作为各种输入的函数。它还将把流出率与太阳风输入参数联系起来。

This project will analyze data from the Fast Auroral Snapshot Small Explorer (FAST) satellite in conjunction with solar wind data from the ACE and WIND spacecraft. It will examine the processes that control the outflow of ions from the polar ionosphere. In particular it will determine the relative importance of large scale Joule heating, Alfven wave heating and heating due to electron precipitation. The work will produce a set of empirical scaling laws that can be used to parameterize ion outflow rates as a function of the various inputs. It will also relate the outflow rates to the solar wind input parameters.
