Committee Historical Members Overview


Committee Charge

The Electromagnetic Advisory Committee (EMAC) will review and provide advice to the IRIS MT manager, the Portable Program Manager, and the PASSCAL Standing Committee (PASC) on the operation, evolution, and technical performance of the PASSCAL Magnetotelluric Program and any EarthScope follow-on magnetotelluric (MT) activities. Responsibilities include working with management to oversee the support of existing long-period MT systems for PI use at Oregon State University and the concurrent development of an integrated facility for portable MT observations at the PASSCAL Instrument Center. The committee will also dialog with Federal stakeholders on the assessing space weather hazards with targeted MT surveys, such as the effort to complete the MT-Transportable Array across the Lower-48 U.S.

The EMAC is neither a science planning nor operations committee, but it should review MT activities in the context of the science framework of SAGE-II and the Federal Space Weather Action Plan. The EMAC will cultivate and incorporate community input and participation regarding the operational and scientific aspects of the MT effort, via convening of special interest groups and other mechanisms. The MT Project Lead and the MT Subaward PIs (both from OSU and the PASSCAL Instrument Center at NMT) will be the primary IRIS staff liaisons with the EMAC and will coordinate with the EMAC Chair to develop topics and questions for review and action by the committee and also report to the PASC. The committee will meet virtually, no less than twice per year, and will provide an annual written report to the PASC, the IRIS President, and Board of Directors. Additionally, the EMAC 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. The EMAC chair will sit as an ex officio member of the PASC.
