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>

pressure.h5：该数据集包含来自27台气压计的大气压强观测数据。每个数据组对应单台气压计的大气压强数据集，单组数据集内：第一列为世界时（单位：秒），第二列为大气压强（单位：百帕，hPa）。
seismometer.h5：该数据集包含MVP-LAI系统中单台地震仪采集的地面振动数据。每个数据组对应单台地震仪的地面振动数据集，单组数据集内：第一列为世界时（单位：秒）；第二、三、四列依次为地面振动的南北向、东西向与垂直分量（单位：计数，count）。
TEC.h5：该数据集包含来自216台地基全球导航卫星系统（GNSS）接收机的总电子含量（Total Electron Content，TEC）观测数据。每个数据组对应单台地基GNSS接收机的TEC数据，每组包含三个数据集，分别对应从北斗地球静止卫星G1、G2和G3反演得到的TEC。每个数据集内：第一列为世界时（单位：秒），第二列为总电子含量（单位：TECU）。
