Testing the interactive computer method (IM) for producing K indices with the data of the Hurbanovo and Budkov magnetic observatories

Original language description

It is generally accepted that the geomagnetic K indices derived by experienced observers are of great value. The interactive method (IM) based on the traditional hand-scaling methodology is tested in this study. The tests are performed utilising the data from the Hurbanovo and Budkov magnetic observatories. These data include both digital records of the geomagnetic field and hand-scaled K indices that had been derived by experienced observers. The authentic K indices from Hurbanovo cover the year 1997 and the same kind of data from Budkov covers the years 1994-1999. In addition to these data, hand scaled K indices are used which were derived by the experienced observer from printed digital magnetograms for both of the observatories for the years 2000-2003. The results of this study indicate that for high values of K indices (the values being at least 5) the tested method follows the traditional hand scaling better than the widely used computer methods FMI and AS. On the other hand, for the K indices less than 5 the tested method turns out to be the worst when compared with the FMI and AS methods. For very low geomagnetic activity (K-index values equal to 0) the performance of the tested method is comparable to the two computer methods.
