Reconstructed high-rate SEIS data recorded during HP3 hammering from the NASA InSight mission to Mars

The NASA InSight lander successfully placed a seismometer on the surface of Mars. Alongside, a hammering device was deployed that penetrated into the ground to attempt the first measurements of the planetary heat flow of Mars. The hammering of the heat probe generated repeated seismic signals that were registered by the seismometer. However, the broad frequency content of the seismic signals generated by the hammering extends beyond the Nyquist frequency governed by the seismometer's sampling rate of 100 samples per second. Here, we provide data that was reconstructed at a higher sampling rate of 2000 samples per second using a dedicated de-aliasing algorithm described in the accompanying article. This archive will be updated regularly with new data acquired on Mars. For a detailed data description and instructions on how to cite this dataset, please refer to the README file.

美国国家航空航天局（NASA）洞察号（InSight）着陆器成功将地震仪（seismometer）安置于火星表面。与此同时，着陆器还部署了锤击装置，可穿透地层以首次尝试测量火星的行星热流。热探针的锤击会产生重复的地震信号，并被该地震仪记录下来。然而，锤击产生的地震信号所包含的宽频成分，超出了该地震仪以100采样/秒的采样率所限定的奈奎斯特频率（Nyquist frequency）。本数据集提供了借助配套文章中详述的专用去混叠（de-aliasing）算法，以2000采样/秒的更高采样率重构得到的相关数据。该数据档案库将定期更新火星上获取的最新观测数据。如需获取详细的数据说明及该数据集的引用规范，请参阅README文件。
