2023 Workshop: Advances in Electrojet Currents
Andrew Pepper
Astrid Maute
Electrojet currents are ubiquitous and of extreme importance
to Earth’s ionosphere and upper atmosphere dynamics. In
high-latitude, the auroral electrojet (AEJ), which has
remarkable strength and persistence, drives many of the high-
latitude phenomena. In low-latitude, the equatorial electrojet
(EEJ), the narrow band of enhanced eastward flowing currents,
resides in a system of highly coupled neutrals and plasma.
Many advances in the study of these currents have been done
in the past few years. From the study of the EEJ using SWARM
data, to the use of SuperMAG to aid AEJ current modeling, to
the upcoming EZIE mission to study the mesoscale AEJ; the
community has produced many investigations on the
electrojet currents. This workshop aims to showcase the latest
advances on the study of electrojet currents.

Proposed science question(s) to be addressed:
What are the advances in the measurement techniques
to study electrojet currents?
What are the latest numerical techniques to reconstruct
electrojet currents?
What are the current investigations in the electrojet
currents modeling?
How the associated questions will be addressed:
We will invite speakers to cover each of these questions
from multiple points of view. This will be well distributed
between ground-based and space-based, modeling and
measurement techniques. An effort for covering
different backgrounds will be made to produce an
inclusive line-up.
