Local Seismic Cultural Noise data of National Capital Region, India

Local Seismic Noise waveforms recorded by the Seismic Sensing Nodes, developed by CSIR-Central Scientific Instruments Organisation (CSIR-CSIO, Chandigarh, India), placed in five locations of NCR, India from Oct'14 - Feb'19 are collected. This database contains 38030 tri-axial seismic noise accelerograms and corresponding metadata. The metadata and raw waveform data are stored in a BSON formatted files titled header.bson and accelerogram.bson respectively.

Each accelerogram record contains header information regarding Peak Ground Acceleration ( tri-axial PGA) at the sensor site. Some of the local noise records also contain signals generated due to strong distant earthquakes or insignificant local tremors from nearby fault regions. These records are significantly less in number and recorded partially in separate event files. Hence, due to the unconfirmed nature of sources, these files are included in this local noise dataset.

本数据集收集了由印度昌迪加尔CSIR中央科学仪器组织（CSIR-Central Scientific Instruments Organisation, CSIR-CSIO）研发的地震传感节点所记录的本地地震噪声波形，该节点于2014年10月至2019年2月部署在印度国家首都辖区（National Capital Region, NCR）的五个观测点位。本数据集共包含38030组三轴地震噪声加速度记录及其配套元数据，元数据与原始波形数据分别存储于名为header.bson与accelerogram.bson的BSON格式文件中。

每组加速度记录均包含传感器点位处的峰值地面加速度（Peak Ground Acceleration, PGA，三轴版本记为tri-axial PGA）相关头文件信息。部分本地噪声记录中还包含由远距离强震或附近断层区域产生的微弱局部微震信号。此类记录的数量相对较少，且部分存储于独立的事件文件中。鉴于其信号来源尚未明确，此类文件仍被纳入本本地噪声数据集。
