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：包含27台气压计采集的大气压强数据。每个分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（秒），第二列为大气压强（百帕，hPa）。<br>seismometer.h5：包含MVP-LAI系统中1台地震仪采集的地面振动数据。每个分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（秒）；第二、三、四列依次对应地面振动的南北向、东西向与垂直分量，单位为count。<br>TEC.h5：包含216台地基GNSS接收机采集的总电子含量（Total Electron Content, TEC）数据。每个分组对应单台地基GNSS接收机的TEC数据集，每组包含3个数据集，分别为北斗地球静止卫星（G1、G2、G3）反演得到的总电子含量。每个数据集内，第一列为世界时（秒），第二列为总电子含量（TECU）。
