PASSCAL Software

PASSCAL provides open-source software for downloading seismic data from REF TEK RT72A, RT130 and RT125, and Quanterra Q330 recorders, for quality assessment, and for conversion to other data formats for analysis and archiving at the IRIS Data Management Center.

We currently provide binaries of all PASSCAL software for Fedora Core LINUX, MacOS X, and SUN Solaris. For other operating system versions, we recommend that you compile the source code. (PQLII downloads are separate; see the PQLII page.)

Please send any bug reports to the bug tracking system or send an e-mail to passcal [at] passcal [dot] nmt [dot] edu. Be sure to include the operating system type and version number, an example command line, sample data if possible, and the version number of the problem code. Version numbers of PASSCAL code are YYYY.JJJ where YYYY and JJJ are the year and julian day of the revision.

Installation Instructions

The first step to getting PASSOFT installed on your system is to download the correct installer/package.  Packages for Mac OSX, Linux, Solaris, or Source Code are presented here.

Antelope

IRIS no longer maintains a license agreement with Boulder Real Time Technologies (BRTT) providing Antelope realtime software to IRIS member institutions. However, BRTT now provides Antelope to all educational institutions within the United States (details).  PASSCAL has a separate license specifically for the archiving of PASSCAL experiments, and we install Antelope on all field computers.  If you need Antelope for archiving your PASSCAL project, please data_group [at] passcal [dot] nmt [dot] edu (email the Data Group).

PH5

PH5 is the PASSCAL recommended archival format for active, passive, and mixed source data sets. PASSCAL has transitioned to PH5, PASSCAL's implementation of the hierarchical data format, version 5 (HDF5) data model, as the preferred archival format. The strengths of HDF5 make it an attractive model for an active source archival data format.

PH5 is a unified archiving format designed to make archival and retrieval of data as simple as possible. PH5's architecture also allows for quick editing of experiment metadata. This is because metadata is separated from the rest of the data allowing the metadata data to be updated and edited without having to reprocess and transmit the entire dataset of an experiment.
