Individual wave propagations in the ionosphere and the atmosphere triggered by the Hunga Tonga-Hunga Ha'apai underwater volcano eruption on 15 January 2022

pressure.h5: atmospheric pressure from 27 barometersOne group contains the data of atmospheric pressure from one barometer. In the dataset of a group: The first column is the universal time (sec). The second column is the atmospheric pressure (hPa).<br>seismometer.h5: ground vibrations from 1 seismometer at the MVP-LAI systemOne group contains the data of ground vibrations from one seismometer. In the dataset of a group: The first column is the universal time (sec). The second, third, and fourth columns, respectively, contain the north-south, west-east, and the vertical components of ground vibrations (count).<br>TEC.h5: Total Electron Content (TEC) from 216 ground-based GNSS receiversOne group contains the TEC data from one ground-based GNSS receiver. Each group contains three datasets including the TEC retrieved from the BeiDou geostationary satellites (G1, G2 and G3). The first and second columns are the universal time (sec) and TEC (TECU), respectively, in each dataset.<br>
