# Magnetic field enhancements in the solar wind: Diverse processes manifesting a uniform observation type? [https://doi.org/10.5061/dryad.m0cfxpp9v](https://doi.org/10.5061/dryad.m0cfxpp9v) Please find 3-D data for Figures 2, 3 and Figures 4, 5 of the paper with the same title: Ying-Dong Jia, Hairong Lai, Nathan Miles, et al. Magnetic Field Enhancements in the Solar Wind: Diverse Processes Manifesting a Uniform Observation Type? *Journal of Geophysical Research: Space Physics*, 129(3), e2023JA032255. [https://doi.org/10.1029/2023JA032255](https://doi.org/10.1029/2023JA032255) The 1-D data in Figures 3 and 5 can be extracted from these two 3-d datasets with the description in the paper, respectively. \**Figures 2 and 3: ** Dust3DMFMHDT008.zip Time-dependent 3-D multifluid MHD model result of charged dust in the solar wind at 1 AU. This data is at 8 minutes after the simulation starts. In this ASCII data, the first several lines contain a header that lists the names of the variables. **Figures 4 and 5:** T=00h: IFR3DHMHDT000.zip T=07h: IFR3DHMHDT007.zip T=10h: IFR3DHMHDT010.zip T=17h: IFR3DHMHDT017.zip Time-dependent 3-D Hall MHD model results of interlaced magnetic flux ropes (IFRs). The four files contain simulation results at 0, 7, 10, and 17 hours. The list of variables is included in the header of the file. These four files are also used to generate Figures 1a, 2a, 2b, and 3 in the second paper mentioned below. **After these, there is one additional file, of the same Hall MHD IFR case, except now H=-1 at x>0.** T=17h: IFR3DnHMHDT017.zip This data file is used for Figures 1b and 2d in another paper: Jia, Ying-Dong, Yi Qi; Xueyi Wang et al.

# 太阳风中的磁场增强：多样过程呈现统一观测类型？[https://doi.org/10.5061/dryad.m0cfxpp9v]

请获取同标题论文中对应图2、3以及图4、5的三维数据：贾应东、赖海龙、内森·迈尔斯（Nathan Miles）等. 太阳风中的磁场增强：多样过程呈现统一观测类型？*Journal of Geophysical Research: Space Physics*，129(3), e2023JA032255. [https://doi.org/10.1029/2023JA032255]

图3与图5中的一维数据可分别根据论文中的描述，从上述两个三维数据集提取得到。

**图2与3：** Dust3DMFMHDT008.zip 对应太阳风1天文单位（AU）处带电尘埃的时变三维多流体磁流体动力学（multifluid MHD）模型结果，该数据采集于模拟启动后8分钟时刻。该数据为ASCII格式，其前若干行包含变量名称列表的文件头。

**图4与5：**
T=00h: IFR3DHMHDT000.zip
T=07h: IFR3DHMHDT007.zip
T=10h: IFR3DHMHDT010.zip
T=17h: IFR3DHMHDT017.zip
上述压缩包对应交错磁通量绳（interlaced magnetic flux ropes, IFRs）的时变三维霍尔磁流体动力学（Hall MHD）模型结果。四个文件分别包含模拟启动后0、7、10、17小时的仿真结果，变量列表包含在各文件的文件头中。上述四个文件还被用于生成下述第二篇论文中的图1a、2a、2b与3。

另有一个同霍尔MHD IFR工况的附加文件，其x>0区域内H=-1。
T=17h: IFR3DnHMHDT017.zip
该数据文件用于另一篇论文中的图1b与2d：贾应东、齐毅、王学义（Xueyi Wang）等(2024). 空间等离子体磁重联产生的反向螺旋磁通量绳. *Geophysical Research Letters*, 51, e2024GL108270. [https://doi.org/10.1029/2024GL108270]
