CEDAR email: Special issue in Frontiers in Astronomy and Space Sciences "Understanding the Causes of Asymmetries in Earth's Magnetosphere-Ionosphere System”

[Astrid Maute]

Dear colleagues,



We would like to draw your attention to a special issue in Frontiers in
Astronomy and Space Sciences on the topic of "*Understanding the Causes
of Asymmetries in Earth's Magnetosphere-Ionosphere System*”: https://www.
frontiersin.org/research-topics/30439



We would highly appreciate original research papers on this topic. We also
encourage submission of review papers as well as perspective papers looking
into the future of this research area. Abstract deadline is 31 March,
and *manuscript
deadline is 31 May*. (Note: There is some ability to be flexible, so please
reach out to editors if you want to submit but can’t make the upcoming
deadline.)



About the research topic:

Modern technological infrastructure in the geospace and on the ground
is very sensitive to solar-terrestrial connections leading to space
weather events resulting from the
magnetosphere-ionosphere-thermosphere coupling. Such events are in turn
linked to the high variability of the Sun, eg., long-term, solar activity;
middle term, seasons; and short term, IMF By and Bz variations. These
phenomena also impact how solar wind and magnetic structures propagate in
the interplanetary space, which subsequently affect the solar
wind-magnetosphere-ionosphere coupling, leading to different effects in
geomagnetic activity.


Recent experimental and modeling studies have shown that solar wind driving
with asymmetric conditions such as, e.g., inclined interplanetary shocks
and other solar wind structures, can control electromagnetic energy input
in the magnetosphere-ionosphere system leading to several asymmetric
responses within the system.

The environment in which space weather drivers take place and interact with
the Earth’s magnetosphere is very large. For this reason, it is
very difficult to grasp a general observational perception of the whole
system because spacecraft observations during a single event or short
period are very sparse. However, there are three ways these difficulties
can be alleviated: first, more satellites are available in the
interplanetary space and the geospace for simultaneous observations
including causes and the subsequent space weather effects; second,
numerical simulations performed with modernized numerical codes and more
robust supercoputers can provide better understanding of the general
dynamics of the system; and third, deep learning techniques can be applied
to large-scale datasets for the improvement of prediction and
forecasting tools and methods. Therefore, the goal of this Research Topic
is to bring together researchers whose research goals are to address
asymmetric effects in space weather drivers and subsequent effects on
the magnetosphere-ionosphere-thermosphere system.

This Research Topic focuses on asymmetric effects of space weather drivers
and the subsequent geomagnetic activity in space and on the ground. We
invite studies that focus on solar activity, including active regions and
coronal holes, asymmetric effects in CME propagation and their impacts on
prediction and forecasting models, inner magnetosphere response (radiation
belt energetic particles, ULF waves and wave-particle interaction) to
asymmetric solar wind driving, magnetic field at geosynchronous orbit,
ionospheric irregularities, auroral substorms, ground dB/dt variations,
neutral mass density enhancements, and many others. This research topic
aims to gather original research papers on observations, simulations, and
application of deep learning techniques. We also encourage the submission
of review papers as well as perspective papers looking into the future of
this research area.
