Dear Colleagues,

At the upcoming AGU Fall Meeting, we will hold a cross-disciplinary session
on the geospace and earth sources of magnetic field perturbations on the
ground. THIS IS A RARE OPPORTUNITY where both geospace and earth aspects in
ground-based magnetometer observations are discussed in the same session,
facilitating future interpretation of geomagnetic data in a broader
geospace-earth framework.

You are cordially invited to participate in this cross-disciplinary
session. All abstracts with ground-based magnetometer observations are
welcome. Please see below for the detailed session description and submit
abstracts *by August 3* online at

Thank you and we look forward to seeing you at the Fall AGU in San

*SM002: Advancing Cross-disciplinary Knowledge of Ground Magnetic
Perturbations: Understanding Sources from the Outer Space to Deep Inside
the Earth*

Magnetic field perturbations detected by ground-based magnetometers provide
valuable information for a range of research topics in earth and space
sciences, such as the electric currents and waves in the magnetosphere and
the ionosphere, subsurface electrical conductivity, potentially damaging
currents in power grids during severe solar storms, and possibly signals
prior to and during major earthquakes. The effects from the outer space to
deep inside the Earth could intertwine in the same magnetic field data,
posing possible challenges in interpreting observations. As ground-based
magnetometer measurements have become network observations, understanding
both geospace and earth effects on ground magnetic perturbations is more
critical than ever to properly study geospace phenomena and earth’s
interior as well as monitor natural hazards with automated algorithms. This
session welcomes all relevant geospace and earth studies based mainly on
ground-based magnetometer data, including those that can advance our
cross-disciplinary knowledge of ground magnetic perturbations.
