We propose to combine an existing solar wind acceleration model with a model for the coronal field and augment it with a state-of-the-art model of the FIP (first ionization potential) effect. This gives us a model that self-consistently predicts the solar wind composition of both fast and slow solar wind including its FIP fractionation. Using standard ballistic backmapping techniques to the source surface we will be able to relate these model results with solar wind composition measurements by ACE/-(Advanced Composition Explorer) and Ulysses/SWICS (Solar Wind Ion Composition Spectrometer on ACE and Ulysses), and SOHO/CELIAS (Charge, Element, and Isotope Analysis System on SOlar Heliospheric Observatory) and draw conclusions about the correlation of the variation of FIP effect and the respective solar source regions.

我们建议将现有的太阳风加速模型与日冕场模型联合收割机结合起来，并使用最先进的FIP（第一电离势）效应模型对其进行增强。这给了我们一个模型，自洽地预测太阳风的快速和慢速太阳风的组成，包括其FIP分馏。使用标准的弹道反映射技术到源表面，我们将能够将这些模型结果与ACE/-（Advanced Composition Explorer）和Windows/SWICS（ACE和ESTA上的太阳风离子成分光谱仪）和SOHO/CELIAS（电荷，元素，太阳日光层观测站的同位素分析系统）并得出了FIP效应变化与各自太阳源区的相关性。
