Fridrich VALACH - Magdalena VACZYOVA - Peter DOLINSKY - Melinda VAJKAI: Substitution for lost one-hour means of the geomagnetic elements for the first half of the 20-th century at the Hurbanovo Geomagnetic Observatory by means of neural networks. In Contribution to Geophysics and Geodesy, vol. 43/2, 2013, pp. 125-40.

The one-hour means of the geomagnetic elements are stored in three data files as follows:

Magnetic declination (element D): NN model HRB 1-hour D.tar.gz

Horizontal component (element H): NN model HRB 1-hour H.tar.gz

Vertical component (element Z): NN model HRB 1-hour Z.tar.gz

All of the above-mentioned data files are organized in three columns:

1. value of one-hour mean,

2. consecutive number of the one-hour period within a day ;

3. date.

The annual means of all three geomagnetic elements, computed from the one-minute means, are stored here: NN model HRB annuals.tar.gz
