title: Comparative statistical study of mid-latitude MSTIDs over two latitudinal regions using dense GNSS network
abstract: This work is devoted to potential sources and mechanisms of the mid-latitude MSTIDs formation based on the analysis and comparison of statistical data in two regions: 1 region near Samara (~ 55 N. 50 E), 2 region near Sevastopol (~ 45 N, 35 E). The data obtained using a dense GNSS receivers network (> 150 pcs.) in the European part of the Russian Federation. The study was carried out using a new statistical method for determining the vertical slopes of the MSTIDs phase front. It was found that s
