Dear colleagues,

We cordially invite you to submit abstracts to our 2025 AGU session titled
"SA004 - Advances in understanding the characteristics of auroral
precipitation and its effects in the magnetosphere-ionosphere-thermosphere
system". More details about this session can be found here with a button to
directly submit your abstract:
https://agu.confex.com/agu/agu25/prelim.cgi/Session/249054. Please don't
hesitate to reach out if you have any questions (Dong Lin,
ldong.aurora at gmail.com);

Session description: Auroral precipitation are magnetospheric particles
that are lost in the upper atmosphere. It is one of the most well-known and
yet poorly understood phenomena in space physics. Various physical
mechanisms can drive particle precipitation resulting in distinct energy
spectra, spatial distribution, and variability with solar wind conditions
and geomagnetic activity levels. Auroral precipitation is an important
ionization source in the ionosphere-thermosphere (I-T) system and changes
the upper atmospheric states and high-latitude ionospheric conductivity,
which impacts magnetosphere-ionosphere-thermosphere (MIT) coupling
processes such as plasma convection, current system, ion drag and Joule
heating. Recent advances in observational and computational capacities have
enabled novel understanding and quantification of auroral precipitation and
its impact on MIT coupling and global I-T dynamics. We welcome
presentations on advances and/or challenges in the driving mechanisms and
characteristics of auroral precipitation, and its regional and global
effects in the MIT system using observations and/or models.
