The PI will combine data analysis and modeling to investigate the degree to which the Sun's magnetic flux opens into the heliosphere and how this flux varies during the course of the solar cycle. He intends to explore the conjecture that Wang and Sheeley (1995) incorrectly applied the Mount Wilson Observatory correction factor to Wilcox Solar Observatory magnetograms. Among other issues, the PI plans to study the contribution of interplanetary CMEs to the magnetic flux measured at 1 AU by interplanetary spacecraft, to determine the best correction factors to apply to synoptic magnetograms from various solar observatories, and to deduce the implications of these results for theories of magnetic flux transport in the solar corona and the build-up of magnetic flux in the heliosphere.This research is relevant to the National Space Weather Program and SHINE. The PI asserts that understanding the basic magnetic structure of the solar corona and how it connects to the heliosphere is a prerequisite to eventually predicting space weather effects. The objectives of this project directly address questions raised by working group sessions at the recent 2006 SHINE workshop.

PI 将结合数据分析和建模来研究太阳磁通量进入日光层的程度以及该磁通量在太阳周期过程中如何变化。他打算探索 Wang 和 Sheeley（1995）错误地将威尔逊山天文台校正因子应用于威尔科克斯太阳天文台磁力图的猜想。除其他问题外，PI 计划研究行星际日冕物质抛射对行星际航天器在 1 天文单位测量的磁通量的贡献，以确定适用于来自各个太阳观测站的天气磁图的最佳校正因子，并推断这些结果的含义用于太阳日冕中磁通量传输和日光层中磁通量累积的理论。这项研究与国家空间天气计划和 SHINE 相关。 PI 声称，了解日冕的基本磁结构及其与日光层的连接方式是最终预测太空天气影响的先决条件。该项目的目标直接解决最近 2006 年 SHINE 研讨会上工作组会议提出的问题。
