CEDAR email: URSI GASS 2026 Commission H Sessions: Abstract Deadline February 9

[Robert Marshall]

The triennial URSI General Assembly and Scientific Symposium (URSI GASS) will be held August 15-22, 2026, in Krakow, Poland. The abstract submission deadline has been extended to February 9, 2026. Details on the conference can be found at https://www.ursi-gass2026.pl/.

Also, don’t forget URSI's Young Scientist award program: a limited number of awards are available to assist young scientists from both developed and developing countries to attend this meeting. More details here: https://www.ursi-gass2026.pl/youngscientist

Below you will find a brief overview of the sessions led by Commission H; the complete list of sessions and their descriptions are available here: https://www.ursi-gass2026.pl/guidelins
