Correlations of the diurnal peak frequency variations of Schumann resonance modes 1993-2016 at NCK station, Hungary

The files in the archive contain Pearson correlation coefficients calculated between the diurnal variation of the peak frequency (DPFV) of the Schumann resonance mode indicated in the name of the file and the average DPFV of all January or July months in the covered time interval: 9 July 1993 - 31 December 2016. None values indicate missing data. The "Uncertainty indicator" is 1 if the quality parameter of the Schumann resonance frequency data, which can be between 0 and 1, had a value lower than 0.5 on that day. Schumann resonance records of the vertical electric component of the atmospheric electromagnetic field were used to compute the correlations. The data was recorded in the Széchenyi István Geophysical Observatory (NCK, 16.7° E, 47.6° N).
