USArray Data Transportable Array and Reference Network data receive QA:

USArray Quality Assurance Report problems that can be fixed Document problems that cannot be fixed Provide information so that others can characterize data quality

USArray Quality Assurance Spotting problems: Automated Metrics Synthetics: events and earth tides Three analysts review: waveforms metadata metrics & synthetics

Automated Metrics QUACK Power Spectral Density (PSD) tools hardware problems instrument response issues noise characterization

Automated Metrics Station Ranking (PSD weekly modes) pinpoints anomalous stations

Synthetics hardware problems instrument response issues 2011/10/28 Central Peru, Mw=6.9 Earth tides hardware problems instrument response issues phase, orientation errors
