The Incorporated Research Institutions for Seismology (IRIS) invites
community input on the facility for portable magnetotelluric (MT)
instrumentation at the PASSCAL Instrument Center (PIC). Establishing
this facility will involve procuring ~$1.4M in instruments through 2023
and developing new data handling capabilities and support for Principal
Investigators by late 2020. IRIS encourages established practitioners of
MT science, IRIS community PIs who are interested in working with MT
data for the first time, and other stakeholders to complete a survey on
the PASSCAL MT program. Feedback from a range of potential users will
ensure that this facility accounts for diverse community needs. The
survey includes multiple choice and short response questions and should
take less than 30 minutes to complete:

More information on the PASSCAL MT facility can be found here:

Currently, EarthScope-era long-period MT instruments (NIMS) may be
reserved through the PIC scheduling system
( under the PASSCAL instrument use

The IRIS Electromagnetic Advisory Committee has organized two technical
working groups to guide the selection of new instrumentation and
development of dirt-to-desktop workflows for PASSCAL MT. The charters
and memberships of these working groups are linked through the EMAC
governance page (
Feedback received from the community will help to inform these groups
going forward.

A Request for Information letter to the manufacturers of magnetic and
electric field sensors and dataloggers will be posted in early summer to
begin the process of identifying potential instrumentation for PASSCAL MT.

General feedback is solicited in the survey and may also be sent to IRIS

Please respond to the survey by May 31, 2019.
