AMPERE GRD & IRD Data (2010-Mar)

2010-Mar 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.

2010年3月的AMPERE GRD与IRD数据集。AMPERE IRD文件包含采用全球坐标系（地理坐标系与AACGM坐标系）的半球ΔB（delta-B）观测数据。该数据集以2分钟分辨率被分块为10分钟的“数据块”，以供拟合算法使用。在前期处理中被标记为“无效”的测量数据，在存入IRD文件前已被剔除。AMPERE GRD文件包含以2分钟分辨率存储的半球ΔB（delta-B）与伯克兰电流（Birkeland current）拟合数据。
