Fig. 6From: Advective diffusion of volcanic plume captured by dense GNSS network around Sakurajima volcano: a case study of the vulcanian eruption on July 24, 2012L1 frequency signal-to-noise ratio (SNR) (S1) time series relative to the previous day at stations 0719, 0720, and 0721 in each satellite. The SNR data of the day before the eruption day were subtracted from the data of the day of the eruption to account for pure sidereal shiftingBack to article page
