Magnetic results 1990: Lerwick, Eskdalemuir, and Hartland observatories (United Kingdom)
Abstract
Measurements made from 1 Jan. - 31 Dec. 1990 at the United Kingdom geomagnetic observatories at Lerwick, Eskdalemuir, and Hartland are reported. The three observatory sites are described, with notes of any changes made during the year. A description of the Automatic Remote Geomagnetic Observatory System (ARGOS), deployed at each observatory since 1st Jan. 1987 is given. The method of collecting the data from each observatory, the quality control procedures, and the method of reducing the data to absolute values are outlined. The presentation of the data is principally in graphical form, with plots of daily and hourly mean values for each year, and complete sets of daily magnetograms derived from minute values. A diskette containing the hourly mean values, produced as a companion to this volume, is available on request. An annual report of the work carried out by the geomagnetism group during the year in instrumentation and data processing techniques is given. Some examples of the use of geomagnetic data in commerce and science are also given.
