AMPERE rawdB Data (2014)

2014 AMPERE rawdB data. Measurements of geomagnetic field perturbations associated with Birkeland currents. Derived from Iridium spacecraft magnetometers. Data are stored in Earth-Centered Inertial (ECI) coordinates, with pseudo space vehicle identifiers, quality flags and exact times.2014年AMPERE原始dB数据集。本数据集收录了与毕尔克兰德电流（Birkeland currents）相关的地磁场扰动测量数据，源自铱星航天器搭载的磁强计。所有数据采用地心惯性（Earth-Centered Inertial, ECI）坐标系存储，包含伪航天器标识符、质控标记与精确时间信息。
