IRIS PASSCAL Support Services
The number of instruments available for use in experiments is frequently used to measure PASSCAL’s progress. However, the scope of the facility extends well beyond the hardware resource alone.The support the PIC provides to users is also essential to the overall success of a given experiment. PASSCAL support has evolved through time in response to experiment methodologies and technological advances, with a continuing emphasis on improving data return and finding more efficient methods of operation. Support provided by the PASSCAL Instrument Center encompasses equipment support, logistics support, user training, experiment support, software support, and data processing support.
Governance and Staffing
IRIS PASSCAL is given oversight by a standing committee representing the seismological community. The IRIS PASSCAL program is managed by Dr. James Gridley. The IRIS PASSCAL Instrument Center is managed by Dr. Bruce Beaudoin.
