ABSTRACT

The paper considers local modeling of the ionosphere in the polar region based on GNSS observations at permanent FAGS and IGS stations. The methodology of joint use of stations belonging to different networks for local monitoring of complete electronic content is presented. The results of monitoring in the area from 10° to 50° in longitude and from 65° to 75° in latitude for the time period 07/9/2020 to 07/16/2020 are presented. 8 GNSS observation stations located inside and in the vicinity of this area were used for monitoring. Local models of the spatial distribution of the vertical total electronic content in the form of Taylor series expansion parameters are obtained. The average square error for the central point of the model averaged 0.12 TECU, and the maximum value was 0.16 TECU. During the time period under review, intense ionospheric disturbances were observed, expressed in a sharp change in the total electronic content, which was previously associated with the passage of an auroral oval through the region under consideration. To confirm this hypothesis, data from the DMSP-F18 spacecraft was analyzed and it was found that during the observation period of the disturbances, the auroral oval passed directly through the region under consideration and a high intensity of disturbances was observed. It is determined that during the passage of an auroral disturbance, the variability of the vertical total electronic content increases by an average of 4.9 times.
