“…Through the efforts of the GC RAS in 2014, it was equipped with the modern magnetometric instrumentation, and in 2016 the first definitive data set for 2015 was produced. These data were accepted by INTERMAG-NET, and the observatory was officially included into the network (Soloviev et al 2015;Sidorov et al 2017). The continuous data recording at the observatory are provided by the following instruments: • FGE 3-axial fluxgate magnetometer (DTU, Denmark) for recording the variations of the EMF components; • GSM-19 scalar magnetometer (Gem Systems, Canada) for recording the modulus of the EMF vector.…”

We propose a new approach to the calculation of regular baselines at magnetic observatories. The proposed approach is based on the simultaneous analysis of the irregular absolute observations and the continuous timeseries deltaF, widely used for estimating the data quality. The systematic deltaF analysis allows to take into account all available information about the operation of observatory instruments (i.e., continuous records of the field variations and its modulus) in the intervals between the times of absolute observations, as compared to the traditional baseline calculation where only spot values are considered. To establish a connection with the observed spot baseline values, we introduce a function for approximate evaluation of the intermediate baseline values. An important feature of the algorithm is its quantitative estimation of the resulting data precision and thus determination of the problematic fragments in raw data. We analyze the robustness of the algorithm operation using synthetic data sets. We also compare baselines and definitive data derived by the proposed algorithm with those derived by the traditional approach using Saint Petersburg observatory data, recorded in 2015 and accepted by INTERMAGNET. It is shown that the proposed method allows to essentially improve the resulting data quality when baseline data are not good enough. The obtained results prove that the baseline variability in time might be quite rapid.

Soloviev A., Kopytenko Yu., Kotikov A., Kudin D., Sidorov R. 2015 Abstract. The possibilities of using the anomality measures (AM) in the problems of determining periods of increased and decreased geomagnetic activity, as well as the dependences of the AM average values on geomagnetic latitude in different phases of geomagnetic storms was investigated.…”
