北京、佘山、长春、拉萨、广州、武汉、兰州、乌鲁木齐地磁台在中国最早开始地磁观测,系统收集、清理8个地磁台在1985—1990年的历史资料,采用数码拍照和人工录入方式,实现纸质资料数字化,同时研制数据入库软件,将梳理后的数据导入“十五”数据库,并进行质量审核,实现珍贵历史资源的电子化、数据化、标准化和规范化,为数据的后续使用奠定基础。本数据集展示了8个地磁台站在1985—1990年的地磁观测数据,数据内容由磁偏角(D)、水平强度(H)和垂直强度(Z)3个要素的绝对时均值组成。利用该数据集,可以开展地磁场、空间天气以及关系国计民生的导航、通讯、电网、高铁、油气管道等的研究工作。
In China, the geomagnetic measurements were first started at Beijing, Sheshan, Changchun, Lhasa, Guangzhou, Wuhan, Lanzhou, and Urumqi geomagnetic observatories. We systematically collected and cleaned up the historical original paper data medium of 8 geomagnetic stations from 1985 to 1990. We use digital photography and manual input approaches in order to facilitate the digitization of these data. At the same time, software was compiled for importing digitized data into a database, and simple quality control of the digitized data has been conducted. These works have enabled the realization of the electronic, digitization, standardization, and normalization of precious historical resources, and laid the foundation for the subsequent use of data. This dataset shows the measurement data of eight geomagnetic observatories from 1985 to 1990. The dataset consists of the absolute hourly mean values of the declination (D), horizontal (H), and vertical components (Z). Using these data, research work on the geomagnetic field, space weather can be carried out, and navigation, communications, power grids, high-speed rail, oil and gas pipelines related to the national economy and people’s livelihood also can be carried out.
