INSTANCE Noise Dataset, version 1

This dataset collects seismic noise waveforms and it is part of INSTANCE. INSTANCE is a data collection of more than 1.3 million seismic waveforms originating from a selection of about 54,000 earthquakes occurred since 2005 in Italy and surrounding regions and seismic noise recordings randomly extracted from event free time windows of the continuous waveforms archive. The purpose is to provide reference datasets useful to develop and test seismic data processing routines based on machine learning and deep learning frameworks. The primary source of this information is ISIDe (Italian Seismological Instrumental and Parametric Data-Base) for earthquakes and the Italian node of EIDA (http://eida.ingv.it) for seismic data. All the waveforms have been sized to a 120 s window, preprocessed and resampled at 100 Hz. For each trace we provide a large number of parameters as metadata, either derived from event information or computed from trace data. Associated metadata allow for the identification of the source, the station, the path travelled by seismic waves and assessment of the trace quality. The total size of the data collection is about 330 GB. Waveforms files are available either in counts or ground motion units in hdf5 format to facilitate fast access from commonly used machine learning frameworks.

本数据集收录地震噪声波形，为INSTANCE数据集的组成部分。INSTANCE是一个涵盖超130万条地震波形的数据集，其中的数据既源自2005年以来意大利及周边区域的约5.4万次精选地震，也包含从连续波形档案的无事件时窗中随机抽取的地震噪声记录。本数据集的研发目的是提供可供基于机器学习与深度学习框架开发、测试地震数据处理流程的参考数据集。本数据集的主要信息来源为：地震相关数据取自意大利地震仪器与参数数据库（ISIDe，Italian Seismological Instrumental and Parametric Data-Base），地震数据则取自EIDA（欧洲地震数据集成档案馆）的意大利节点（http://eida.ingv.it）。所有波形均被规整为120秒时长的时窗，经过预处理并以100Hz的采样率重采样。为每条地震波形道提供了大量元数据参数，这些参数既源自事件信息，也可从波形道数据中计算得到。配套的元数据可用于识别震源、观测台站、地震波传播路径，并评估波形道的质量。该数据集的总容量约为330GB。波形文件可按原始计数值或地面运动单位存储，采用hdf5格式，以方便从常用机器学习框架中快速调取访问。
