Magnetic observations collected from Antarctica and Macquarie Island since 1952

Final one minute average values of the absolute geomagnetic field in the north (X), east (Y) and vertical (Z) components in units of nanoTesla (nT).Magnetic variometer data have been collected at Macquarie Is. since 1952; Mawson since 1955; and Casey since 1988. Data were not digital from Macquarie Is. until late 1984; from Mawson until late 1986. They have been digital from Casey since 1988. Data that are currently available from the GA website are not complete, but improving. The status of data availability is available on the website.Particular magnetic elements can be chosen to be plotted or tabulated data are available.

本数据集收录地磁绝对场北向（X）、东向（Y）与垂向（Z）分量的最终1分钟平均值，单位为纳特斯拉（nanoTesla, nT）。磁变仪观测数据自1952年起在麦夸里岛（Macquarie Is.）采集，莫森站（Mawson）自1955年起开展观测，凯西站（Casey）则自1988年起启动数据收集。麦夸里岛的观测数据直至1984年末才实现数字化，莫森站的数字化数据则始于1986年末；凯西站的观测数据自1988年起便已实现数字化。当前可通过GA官网获取的数据集尚不完整，但覆盖范围正持续优化，数据可获取状态可在该官网查询。用户可选择特定地磁要素进行绘图，或获取制表格式的观测数据。
