DMSP F15/F16/F18 2011-2014 Binned Poynting Flux Data

This dataset, created using the esabin Python library, comprises 9 spacecraft-years of electrodynamics measurements from Defense Meteorology Satellite Program F15, F16 and F18 spacecraft. <strong>Users of this data should prefer files which do not contain 'idm_only' in their filenames, as these do not use both components of DMSP ion drift vector measurements.</strong> They are included here to support reproducibility of a upcoming publication. The HDF5 files herein organize this data in equal area bins in magnetic coordinates. Each Group in the files represents one bin. Each Dataset contains the data for one crossing of that bin by a DMSP spacecraft. The name of each Dataset is the approximate time of the crossing as Julian date. Hourly NASA OMNIWeb solar wind and geomagnetic activity parameters are included as attributes for each Dataset. The electrodynamic parameters herein are magnetic perturbation (dB), electric field (E) and ion drift velocity (V). These quantities are scaled from satellite altitude (~850 km) where they were observed to ionospheric altitude (~110 km) using Modified Magnetic Apex coordinates. In the filenames, 'e' represents magnetic eastward and 'n' represents magnetic northward. Also included are geomagnetic-main-field-aligned Poynting flux also scaled to 110km altitude (files with 'poynting' in the name).本数据集基于esabin Python库构建，涵盖来自国防气象卫星计划（Defense Meteorology Satellite Program，DMSP）F15、F16及F18卫星的共计9航天器-年的电动力学观测数据。**请注意，用户应优先选用文件名不含'idm_only'的文件，此类文件未同时使用DMSP离子漂移矢量测量的两个分量**。纳入此类文件仅为支持即将发表的研究论文的可复现性。本数据集采用分层数据格式5（Hierarchical Data Format 5, HDF5）存储，以磁坐标下的等面积分箱规则组织数据。文件中的每个组（Group）对应一个分箱，每个数据集（Dataset）代表一颗DMSP卫星飞越该分箱的单次观测，数据集的命名采用飞越时刻的近似儒略日（Julian date）。每个数据集均附带由NASA OMNIWeb提供的逐小时太阳风与地磁活动参数作为属性。本数据集涵盖的电动力学参数包括磁扰动（dB）、电场（E）以及离子漂移速度（V）。上述参数已通过修正磁顶点坐标（Modified Magnetic Apex coordinates），从观测所在的卫星轨道高度（约850 km）尺度转换至电离层典型高度（约110 km）。文件名中，'e'代表磁东向分量，'n'代表磁北向分量。此外还包含已尺度转换至110 km高度的沿地磁主磁场方向的坡印廷通量（Poynting flux），对应文件的文件名中包含'poynting'字样。
