IRIS System for Portable Assessment of Quality (ISPAQ) is a command line application that calculates seismic data quality metrics locally, by leveraging MUSTANG R-code within a Python client. For LINUX and macOS.
The project is hosted on GitHub:
ISPAQ can calculate over 40 MUSTANG-style data quality metrics using either local miniSEED files or data available through any Data Center that supports FDSN web services. These metrics include basic trace statistics, metrics based on miniSEED state-of-health flags (if available), metrics based on event arrivals, and metrics derived from Power Spectral Densities (PSD). Daily PSDs and Power Density Functions (PDF) can be output as text files. PDF plots are also available, but limited to single day time-spans. All results are computed and stored on the user’s local machine.
