Currently, the United States Geological Survey (USGS) National Earthquake Information Center (NEIC) receives more than 4,000 channels of seismic data from roughly 900 seismic stations distributed around the world in near real time. As the NEIC develops increasingly sophisticated methods for automated data processing, it becomes equally important to develop tools for ensuring that only the highest-quality data are used in rapid earthquake products. In this paper, we present methods and applications for computing long- and short-term, station-specific noise baselines for broadband seismic data channels. Long-term baselines (one year or greater) are useful for determining ambient noise conditions, while short-term...
