Fig. 9From: Ionospheric signatures of repeated passages of atmospheric waves by the 2022 Jan. 15 Hunga Tonga-Hunga Ha’apai eruption detected by QZSS-TEC observations in JapanComparison of the pressure anomaly (blue) and VTEC (black) with the quasi-zenith orbit satellite J03, with nearly vertical line-of-sight, around the first passage of LW. Both the ground GNSS stations (red) and their SIPs at 11.7 UT (pink) are close to the barometers. See Fig. 8 caption for detailsBack to article page
