Locating the solar source regions of slow solar wind is one of the major science goals of ESAs soon to be launched mission Solar Orbiter. In particular, Solar Orbiter will rely on correlating in situ measurements of the solar wind with remote-sensing observations of potential source regions of the slow solar wind by comparing observations of elemental composition. The purpose of our proposed investigation is to assess the validity of the underlying assumptions required for the future analysis of the data acquired by Solar Orbiter with the help of in situ data measured by the Advanced Composition Explorer (ACE) as well as remote-sensing observations from the Michelson Doppler Imager (MDI) and the Extreme ultraviolet Imaging Telescope (EIT) both onboard the Solar and Heliospheric Observatory (SOHO). Both sides are combined with a combination of ballistic and magnetic back-mapping. Therein we will focus mainly on the in situ aspect of the observations.

定位慢速太阳风的太阳源区是欧空局即将发射的太阳轨道器任务的主要科学目标之一。特别是，太阳轨道飞行器将通过比较元素成分的观测结果，将太阳风的现场测量与慢速太阳风潜在源区的遥感观测相关联。我们提出的调查的目的是评估未来分析太阳轨道飞行器获取的数据所需的基本假设的有效性，借助高级成分探测器（ACE）测量的现场数据以及来自太阳和日光层天文台上的迈克尔逊多普勒成像仪（MDI）和极紫外成像望远镜（EIT）的遥感观测 （SOHO）。两侧都结合了弹道和磁背映射的组合。其中我们将主要关注观测的现场方面。
