Geomagnetic observatory hourly and minute means

Hourly and minute means of the geomagnetic field vector components from observatories around the world from, respectively, 1883 and 1969, to the present day. At present there are about 160 observatories. These data are useful for tracking changes in the magnetic field generated inside and outside the Earth. Data are produced by a number of organisations around the world, including BGS. Data are available in plain text from www.wdc.bgs.ac.uk.

全球各地观测站自1883年至1969年以及现今的地球磁场矢量分量每小时及每分钟的平均值数据。目前约有160个观测站参与其中。此类数据对于追踪地球内外生成的磁场变化具有重要意义。全球多个组织机构，包括英国地质调查局（BGS），均参与了数据的生产。数据以纯文本格式可在www.wdc.bgs.ac.uk网站上获取。
