Abstract
We confront the data avalanche: the amount of waveform data available from seismological data centers has been growing enormously over the past few years. This is a highly welcome development from a scientific point of view, but the time and effort spent on identification, retrieval, and quality control of subsets of these data may quickly exceed tolerable limits for an individual researcher.

Data from different data centers may not be available through the same interfaces or may arrive in different formats, which have tended to change over time. This often results in time‐consuming homogenization efforts. The situation has improved in that certain quasistandards have been adopted for data formats; for example SEED, the Standard for the Exchange of Earthquake Data (IRIS Consortium, 1993), has been in use for nearly 20 years. Also, a few Internet data exchange protocols are in wide use now; for example ArcLink, developed within the WebDC project of GFZ and SZGRF (http://www.gfz-potsdam.de, http://webdc.eu), or DHI, a framework for accessing data and metadata from the IRIS DMC using a DHI‐supporting client program (Ahern, 2001).

ObsPyLoad is a software tool that fully automatically queries the metadata holdings of seismological data centers and retrieves all metadata and seismograms of matching attributes via the Internet. Waveforms and metadata can be retrieved from multiple data centers, which is a major advantage over the download tools offered by individual data centers. We currently support downloads from IRIS (via a webservice client), and from ORFEUS (via ArcLink). We expect to add more choices as they become available in the ObsPy framework (see The Choice of Python). Earthquake metadata may currently be retrieved from the Seismic Portal (http://www.seismicportal.eu).

ObsPyLoad can either run in standalone mode from a command‐line interface, or be integrated into other Python code.
