Energetic Precipitation Effects in the Middle and Upper Atmosphere

Session ID#: 82263

Session Description:
Precipitating energetic particles have been shown to be able to change the mean state of the atmosphere. Energetic precipitation with different origins (magnetosphere plasma sheet, radiation belt, solar energetic protons, cosmic rays) can penetrate into different layers of the atmosphere and affect atmospheric chemistry and dynamics in different ways. For example, the changes of ionospheric conductivity in the upper atmosphere due to auroral precipitation directly affect the electrodynamic coupling between the magnetosphere and the ionosphere, and heating and forcing of the atmosphere at different altitudes. Relativistic precipitation produces nitrogen and hydrogen oxides in the middle atmosphere which have both local and global influences on ozone concentration and radiative heating/cooling. This session addresses issues related to the precipitation effects in the middle and upper atmosphere using observations and models. This topic couples the solar, magnetospheric, ionospheric, and atmospheric physics which will be of interest for both atmospheric and heliospheric communities.
