Digitised magnetogram data from three UK observatories (NERC Grant NE/P017231/1)

Digitised magnetogram data from Lerwick, Eskdalemuir and Hartland for two large geomagnetic storms (March 1946 and August 1972). Data have been manually extracted using Enguage Digitizer and verified against hourly mean values from the World Data Centre for Geomagnetism

Statement

Over the past two centuries, observatories measured the daily field variations using light-sensitive photographic paper to produce analogue magnetograms. Around 350,000 magnetograms have been digitally photographed at high-resolution. However, converting the traces to digital values is difficult and time consuming as the magnetograms can have over-lapping lines, low quality recordings and obscure metadata for conversion to SI units. We digitised the traces from two large geomagnetic storms and cross-checked the final digitised values with the recorded hourly mean values from observatory years books.
