- Аннотация: In this work we estimate level of seismic noise at Kyrgyz Network’s (KNET) highmountain stations for 19 years of the time this network operated in real-time mode (1999-2017).To do that for each channel (E – west-east, N – south-north and Z – vertical, all with 100 Hzsample rate) of each station we made fifteen-minute (900 seconds) segments of seismic noise.We took such segments for different seasons (March, June, September, December) and forvarious times of day (00, 06, 12 and 18 hours UTC) for the whole 19 years. We analyzedprobabilistic power spectral density heatmaps and found out some features of KNET’s highmountain station’s operation. These features depend on season-wise weather changes. The worthmonth for all stations is September. In general, when weather is favorable these stations can becharacterized as low-noise ones and their data may be used in various researches.
