Committee Charge
The USArray Advisory Committee is charged with providing advice to the IRIS Board of
Directors and IRIS President on the performance of the USArray component of
EarthScope. The Committee will monitor the operation and evolution of the USArray
facility, and review the contributions of IRIS core programs (DMS, E&O, GSN and
PASSCAL) to the successful implementation of USArray and the science goals of
EarthScope. The Committee is neither a science planning nor operations committee, but
should review USArray operations in the context of the science framework for USArray
and EarthScope.
The Committee will meet as needed, but no less than twice per year, and will provide
semi-annual written reports to the IRIS President and Board of Directors. Reports and
recommendations will also be provided to the NSF EarthScope Program Director(s).
Additionally, the Committee may be charged with reviewing special topics and questions
requiring prompt action.
Members of the Committee are appointed by the Board of Directors and serve renewable
three-year terms.
