| Summary: | We present obspyDMT, a free, open-source software toolbox for the
query, retrieval, processing and management of seismological data sets,
including very large, heterogeneous and/or dynamically growing ones. ObspyDMT
simplifies and speeds up user interaction with data centers, in more
versatile ways than existing tools. The user is shielded from the
complexities of interacting with different data centers and data exchange
protocols and is provided with powerful diagnostic and plotting tools to
check the retrieved data and metadata. While primarily a productivity tool
for research seismologists and observatories, easy-to-use syntax and plotting
functionality also make obspyDMT an effective teaching aid. Written in the
Python programming language, it can be used as a stand-alone command-line
tool (requiring no knowledge of Python) or can be integrated as a module with
other Python codes. It facilitates data archiving, preprocessing, instrument
correction and quality control – routine but nontrivial tasks that can
consume much user time. We describe obspyDMT's functionality, design and
technical implementation, accompanied by an overview of its use cases. As an
example of a typical problem encountered in seismogram preprocessing, we show
how to check for inconsistencies in response files of two example stations.
We also demonstrate the fully automated request, remote computation and
retrieval of synthetic seismograms from the Synthetics
Engine (Syngine) web service of the Data Management Center (DMC) at the Incorporated Research
Institutions for Seismology (IRIS). |
