[Craig Rodger]

Dear colleagues

We would like to encourage you submit abstracts to session A16 "Energetic 
Particle Precipitation into the Atmosphere: Sources and Atmospheric Impacts 
(Div II-D/IAGA Div II-VERSIM/ICMA)" at the IUGG meeting which will occur from

listed below:

-*Thursday, 15 January 2015*, due date for the abstract submission in case of 
an application for a travel grant award; and

-*31 January*, due date for the abstract submission.

*Other important dates to be marked in your calendar:*

-*31 March*, due date for the notification of paper acceptance and successful 
grant application;

-*10 April*, early bird registration deadline.

A16 Energetic Particle Precipitation into the Atmosphere: Sources and 
Atmospheric Impacts (Div II-D/IAGA Div II-VERSIM/ICMA)

Convener: Craig Rodger (Otago, New Zealand)

Co-conveners: Mark Clilverd (Cambridge, U.K.), Bernd Funke (ICMA, Granada, 
Spain)

Description
This symposium is targeted at both, satellite and ground-based and experimental 
observations, as well as theoretical investigations, into the precipitation of 
energetic particles into the D-region ionosphere and below. Particle 
precipitation into the atmosphere is one of the mechanisms for energetic 
electron loss from the Van Allen radiation belts. This is particularly 
significant during and after geomagnetic storms, when the loss rate, and the 
source population, can both increase. Submissions describing other examples of 
energetic particle precipitation affecting the mesosphere and stratosphere, for 
example solar proton events or hard-spectrum substorm precipitation, are also 
relevant for this symposium. Papers considering the precipitation drivers, the 
nature of the particle fluxes, or the impact of the precipitation on the 
ionosphere or atmosphere are welcome. We particularly welcome observations of 
atmospheric chemical changes caused by energetic particles, new measurements 
from the Van Allen Radiation Belt Storm Probes or BARREL balloon campaigns 
showing energetic electron loss examples, or approaches showing how electron 
precipitation impacts can be applied by the atmospheric community. Results from 
the SCOSTEP SPeCIMEN and ROSMIC programmes, as well as from SPARC’s 
SOLARIS-HEPPA activity are solicited. This symposium is co-sponsored by the 
International Commission on the Middle Atmosphere (ICMA) of IAMAS.
