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.
