Description
A collection of continuous envelope functions used to search for tectonic tremor and for data quality analysis. Envelope functions are computed automatically by the Earth and Space Sciences Department at the University of Washington using selected portions of the EarthScope DS waveform archive and are distributed by EarthScope.

Select the stations for which you would like to download envelope functions, then download them using the Get manifest (aria2c) or Get curl script (.sh) buttons.

Use the filter controls below to limit stations by network, year, etc. For more information about the Continuous Envelope Functions Data Product, visit the product page .
