CEDAR email: Call for abstracts 2026 URSI GASS: H03, Drivers, Detection, and Ionospheric Impacts of Precipitation from the Radiation Belts

[Jaynes, Allison N]

Dear Colleagues,
We invite you to submit an abstract to the 2026 URSI GASS Commission H session H03, titled “Drivers, Detection, and Ionospheric Impacts of Precipitation from the Radiation Belts”. URSI GASS will take place August 15-22, 2026, in Kraków, Poland as an in-person conference only. Kraków is a leading tourist destination, with charming historic sites and modern districts, and is home to seven UNESCO World Heritage Sites. Abstract submissions are now open, and the submission deadline is January 25, 2026. Details on the conference can be found at https://www.ursi-gass2026.pl/.

H03 session summary:
Particle precipitation into the atmosphere is believed to be one of the dominant mechanisms for the loss of energetic electron loss from the Van Allen radiation belts, as well as losses of ring current ions. Wave-particle interactions with ULF through to VLF waves are thought to be important drivers of these loss-events. This session is targeted at both ground-based, balloon, and satellite experimental observations, as well as theoretical investigations, into the precipitation of energetic (>10 keV) to relativistic energy electrons or precipitation of ring current ions. Papers considering wave-particle interactions driving losses, measurement of loss fluxes, or the effects of this precipitation on the ionosphere are welcome. Note that studies directed towards radiation belt electron acceleration, transport, or dynamics are likely better suited to the complementary session H02 or H04.

Session conveners,
Allison Jaynes,
Mark Clilverd
