AusPass Data

AusPass is an FDSN server which hosts waveform, station, and earthquake data, as well as links to research done by people at ANU. The primary means of accessing data is via the FDSN protocol which can be accessed directly (e.g. via HTML) or via a 3rd party client such as ObsPy or SEED-Vault.

Waveform Data

AusPass primarily hosts data collected by ANU researchers but also experiments conducted via ANSIR equipment loans, as well as other datasets from people who simply asked us to host their data. We also host some waveform data from external agencies and projects, such as GeoScience Australia's national network AU and the global network IU. This is done as a convenience to our users as much of this data is concurrent and proximial to our networks. Again we reiterate that we only hose SOME of this data, we simply do not have the resources to do a full clone. If we do not have the data you're looking for, it's best to try IRIS/Earthscope. If they don't have it, you should get in touch with Geoscience Australia directly.

AusPass is NOT GeoScience Australia! We are wholly distinct entities.

QA/QC

Where possible, we will fix obvious timing errors such as constant time offsets and clock drifts and host the "fixed" version of the waveform data. Sometimes timing corrections cannot be reliably fixed (e.g. clocks jumping around too much intraday) and they are left as-is. We do not fix north azimuth misalignments. We keep copies of the original raw data as well as a list of timing corrections and are happy to facilitate access to these upon request. If you see any issues, please let us know.

Station Data

For all of the networks and stations in our waveform archive, we also host the accompanying STATION metadata (which includes response information). For networks outside of our control (e.g. AU and IU) we download this metadata from IRIS/Earthscope. Any issues with this data should be directed at the respective agencies in charge of keeping it accurate.

Earthquake Data

In collaboration with Geoscience Australia, we host copies of their global catalog which is derived from the output of the Earthquakes@GA web portal. We do this by manually downloading CSV data and converting it to Seiscomp SCXML, then importing it into our server. Because we must do this manually, our cloned earthquake catalog is only updated monthly. Note that information such as phase arrivals is not provided.
