AMPERE GRD & IRD Data (2016-Jan)

2016-Jan 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.

2016年1月的AMPERE GRD与IRD数据集。
AMPERE IRD文件包含全球坐标系（地理坐标系与AACGM）下的半球磁场增量（delta-B）观测数据。为适配拟合算法的使用需求，该数据集以2分钟的分辨率被分割为10分钟时长的数据块。此前处理流程中被标记为‘无效’的测量数据，在录入IRD数据集前已全部移除。
AMPERE GRD文件包含分辨率为2分钟的半球磁场增量与毕尔克电流（Birkeland current）拟合数据。
