A Study of the Characteristics of the Long Term Fluctuations of the Geomagnetic Field

摘要

The collection, reduction and evaluation of geomagnetic field data at the Weston Geomagnetic Observatory is discussed in terms of the evolution that has taken place in hardware implementation and technological demand. The large quantity of data being generated and a fast turn over of information necessitates one to think in terms of an automatic facility with both analog and digital outputs which are computer compatible. The report will deal briefly with the evaluation, but mainly the theme will be the present system, what it consists of, what it measures, how it is being measured, and how the data is being handled.
