NASA's Voyager 1 Refined Magnetic Field Data (1-10 au)

This dataset contains NASA's Voyager 1 spacecraft in situ measurements of the solar wind for the Cartesian RTN magnetic field (nT), heliocentric distance (au), proton density (cm^-3), and bulk flow speed (km/s), with time resolution 1.92 seconds.<br> The original source for this refined dataset can be found via the Goddard Space Flight Center Space Physics Data Facility (SPDF), for 2 second MAG data and hourly averaged plasma data.<br> The range of heliocentric distance covered in this dataset is from 1-10 au and each file contains a time series of magnetic field measurements over two days.<br> Each file is labeled with the start and end day covered by the magnetic field time series.<br> Information regarding heliocentric distance, proton density, and bulk flow speed in each file are represented by averages over the corresponding two-day interval.<br> These averages were taken from the hourly averaged data, provided by SPDF, over the appropriate time covered by the magnetic field time series.<br> The CDF files have global attributes: 'CREATOR', 'AFFILIATION', 'S/C NAME', and 'DATE CREATED'.<br> Variable keys are 'SSEPOCH' (time), 'BR' (radial magnetic field), 'BT' (tangential magnetic field), 'BN' (normal magnetic field), 'R' (heliocentric distance), 'N' (proton density), and 'VSW' (bulk flow speed), with variable attribute 'UNITS'.<br> The 'SSEPOCH' variable are timed measurements in units of seconds since Epoch (January 1, 1970).<br> The CDF files were generated in Python using the spacepy.pycdf library.<br> For more specifics regarding the magnetic field cleaning methods utilized to produce this dataset, please refer to the Master's Thesis "Voyager 1: Cleaning Magnetic Field Data for Turbulence Studies" and contact the author for any questions related to the thesis or access.<br> Please send any questions/concerns to Manuel Enrique Cuesta at [e-mail] for any problems related to downloading/accessing the data from the CDF files.本数据集包含美国国家航空航天局（National Aeronautics and Space Administration，NASA）旅行者1号（Voyager 1）探测器的太阳风原位测量数据，涵盖笛卡尔RTN坐标系下的磁场（单位：纳特斯拉，nT）、日心距离（单位：天文单位，au）、质子密度（单位：cm⁻³）以及整体流速度（单位：千米每秒，km/s），时间分辨率为1.92秒。 该优化后数据集的原始来源可通过戈达德航天飞行中心空间物理数据设施（Space Physics Data Facility，SPDF）获取，对应2秒分辨率的磁强计（MAG）数据与小时平均等离子体数据。 本数据集覆盖的日心距离范围为1至10天文单位，每个文件包含为期两天的磁场测量时间序列。 每个文件以其所涵盖的磁场时间序列的起止日期进行标注。 各文件中关于日心距离、质子密度与整体流速度的信息，由对应两日时间段内的平均值表征。 上述平均值取自空间物理数据设施（SPDF）提供的、与磁场时间序列覆盖时段相匹配的小时平均数据。 CDF格式文件包含以下全局属性："CREATOR"（创建者）、"AFFILIATION"（所属机构）、"S/C NAME"（探测器名称）以及"DATE CREATED"（创建日期）。 变量键包括："SSEPOCH"（时间）、"BR"（径向磁场）、"BT"（切向磁场）、"BN"（法向磁场）、"R"（日心距离）、"N"（质子密度）以及"VSW"（整体流速度），所有变量均带有"UNITS"（单位）属性。 其中"SSEPOCH"变量为以1970年1月1日为纪元的秒数形式记录的时间测量数据。 本数据集的CDF格式文件通过Python语言借助spacepy.pycdf库生成。 若需了解用于构建本数据集的磁场数据清洗方法的更多细节，请参阅硕士论文《旅行者1号：面向湍流研究的磁场数据清洗》（Voyager 1: Cleaning Magnetic Field Data for Turbulence Studies），若有关于该论文或数据访问的相关问题，请联系论文作者。 若您在下载或访问CDF格式文件中的数据时遇到任何问题，请发送疑问或诉求至Manuel Enrique Cuesta的邮箱：[e-mail]
