Pauken, Zhongwen Zhan, Jacob Izraelevitz, Gerald WalshThis page contains data used in the analysis for the paper titled "The first detection of an earthquake from a balloon using its acoustic signature" in Geophysical Research Letters. This paper performs a data and model-based seismo-acoustic analysis to show the detection of Rayleigh waves generated by a magnitude 4.2 earthquake in July 2019 on a balloon platform at an altitude of 4.8 km.
The dataset provided here contains raw data recorded on five balloon-based barometers. The "Hare" and "Tortoise" CSV files contain time-stamped absolute pressure in bar ("_Baro" suffix) and location data ("_GPS" suffix) for two balloons launched on July 22, 2019 and the "Hare2" and "CrazyCat" CSV files contain the same data for two balloons launched on August 9, 2019. CrazyCat has two files pressure data, one for the lower and one for the upper package, as indicated. Location is provided for only the upper package on CrazyCat. The lower package was vertically 36 meters below. Timestamps are in GPS seconds of the day (i.e. time in seconds UTC since 0000 UTC on the day).
In addition we provide data generated by two simulation tools used in the work - SPECFEM-2D-DG and RW-Atmos. These data are contained in a netCDF file titled "modelData.nc". Measurement stations and source specifications are described in the attributes.
Seismometer data used in this work were downloaded from publicly available data at the Southern California Earthquake Data Center (SCEDC) (doi:10.7909/C3WD3xH1) : https://service.scedc.caltech.edu/
