Long Term study of the Schumann Resonance Regular Variations Using the Sierra Nevada station ground-based magnetometers. Data Salinas Extremera, Alfonso Schumann Resonances Sierra Nevada ELF station We present the data of a study of the Schumann Resonance (SR) regular variations (March 2013 – February 2017) using the ground-based magnetometers from the Sierra Nevada station, Spain (37◦02’N, 3◦19’W). The study is based on the fitting parameters obtained by the Lorentzian fit, calculated for each 10-min interval record, namely, peak amplitudes, central frequencies, width of the resonances and the power spectrum integral for the first 3 SR modes. We consider three time-scales in the study: seasonal, monthly and daily variations. The processed data collected by the Sierra Nevada station are also made public with this work. 2021-11-16T18:44:46Z 2021-11-16T18:44:46Z 2021-10-17 dataset http://hdl.handle.net/10481/71563 10.30827/Digibug.71563 eng http://creativecommons.org/licenses/by-nc-nd/3.0/ open access Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License Universidad de Granada
