在过去的150年里，地磁观测站的实践和仪器有了很大的发展。技术的进步和数据用户群体对近乎实时的更高分辨率、更低噪声数据的需求继续推动着这一发展。此外，观测站之间的合作和建立观测站网络协调了世界各地的标准和做法；提高了用户可获得的数据产品的质量。尽管如此，运营一座高质量的地磁观测站绝非易事。本文列举了地磁观测站复杂运行中的一些普遍问题，记录了观测站仪器和方法的现状。它还根据在Sopron和INTERMAGNET举行的第11届IAGA大会期间所作的介绍，进一步概述了天文台数据质量的最新改进。
Geomagnetic observatory practice and instrumentation has evolved significantly over the past 150 years. Evolution continues to be driven by advances in technology and by the need of the data user community for higher-resolution, lower noise data in near-real time. Additionally, collaboration between observatories and the establishment of observatory networks has harmonized standards and practices across the world; improving the quality of the data product available to the user. Nonetheless, operating a high-quality geomagnetic observatory is non-trivial. This article gives a record of the current state of observatory instrumentation and methods, citing some of the general problems in the complex operation of geomagnetic observatories. It further gives an overview of recent improvements of observatory data quality based on presentation during 11th IAGA Assembly at Sopron and INTERMAGNET issues.
