The Schumann resonances are an electromagnetic phenomenon detectable in the Extremely Low Frequency waveband using a search coil magnetometer. They are created by the continuous discharge of lightning globally. The variation of the intensity and frequency of the resonances can generally be related to (a) the diurnal changes in location and intensity of the global lightning centres, (b) the conductivity properties of the ionosphere and (c) general changes in global temperatures. We have collected and analysed seven years of data (from 2012 to 2019) using two horizontal highfrequency magnetometers installed at Eskdalemuir Geomagnetic Observatory in the UK. The site is magnetically quiet and offers an excellent location to monitor the variation of the Schumann resonances in the 1-50 Hz frequency band. We analyse the variation of the first three Schumann resonances to illustrate the quality of the data and confirm many of the previously observed seasonal variations at other sites globally. We see a long-term decline in the frequencies of each resonance, and evidence for a similar change in the intensity over the seven-year period. © 2019 BBSCS RN SWS. All rights reserved
