[Craig Rodger]

Please consider submitting an abstract to the IUGG – IAGA symposia A06: 
Energetic Particle Precipitation Impacts on the Ionosphere, Upper Atmosphere, 
and Climate System

Convener(s): Mark Clilverd (UK), Craig Rodger (New Zealand), Pekka Verronen 
(Finland)

The IUGG General Assembly is to be held over 11-20 July 2023 at the Messe 
Berlin – City Cube, Berlin, Germany.

Description of A06:
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 - along with the impact of the energetic precipitation on the upper
atmosphere and the coupling of these impacts on the climate system.
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, the impact of the precipitation on the ionosphere or
atmosphere, and the climate system response are welcome. Results from the
SPARC’s SOLARIS-HEPPA community, as well SCOSTEP's PRESTO programme are
solicited.

Timeline:
14 February 2023     Submission deadline
17 March 2023              Abstract acceptance sent to participants

We already have invited speakers lined up on the topics of the use of POES 
electron precipitation fluxes for climate modelling, microburst-produced 
precipitation caused by whistler mode chorus, precipitation of MeV energy range 
electrons by EMIC waves observed by ELFIN, and substorm energetic electron 
precipitation impacts on the atmosphere. Please submit an abstract and join in 
the fun!

We look forward to seeing you in Berlin. Based on the wide range of scientfuic 
sessions, and the positive response from the wider commuity, we expect this 
will be a very exciting conference. Kind regards, Pekka/Craig/Mark
