AMPERE GRD & IRD Data (2014-Nov)

2014-Nov AMPERE GRD and IRD data. AMPERE IRD files contain hemispheric delta-B observations in global coordinates (geographic and AACGM). Data are blocked into 10-minute 'chunks' at 2-minute resolution for use in the fitting algorithm. Measurements flagged 'bad' in the earlier processing are removed prior to entry in IRD. AMPERE GRD files contain hemispheric delta-B and Birkeland current fits at 2-minute resolution.2014年11月AMPERE GRD与IRD数据集。 AMPERE IRD文件包含采用全球坐标系（涵盖地理坐标系与AACGM坐标系）的半球磁场增量（hemispheric delta-B）观测数据。为适配拟合算法，该数据集以2分钟的分辨率被划分为10分钟时长的数据块。早期处理流程中被标记为"无效"的观测数据，在存入IRD文件前已被剔除。 AMPERE GRD文件包含分辨率为2分钟的半球磁场增量与伯克兰电流（Birkeland current）拟合结果。
