Dear Colleagues,

Please consider submitting an abstract to the following SPA-Aeronomy
session at the 2019 Fall AGU Meeting, December 9-13, 2019 in San Francisco
CA.  Abstracts are due Wednesday July 31. Here is the link:

SA008:
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.
