Continuous envelope functions

A collection of continuous envelope functions to search for tectonic tremor and for data quality analysis. Envelope functions are computed automatically by the Earth and Space Sciences Department of the University of Washington utilizing selected portions of the IRIS DMC waveform archive and are distributed by the IRIS DMC.

一组连续包络函数，用于搜索构造地震颤动以及进行数据质量分析。这些包络函数由华盛顿大学地球与空间科学系自动计算，基于所选部分的 IRIS DMC 波形存档，并由 IRIS DMC 分发。
