2023 GEM Summer Workshop
COmparative Planetary Magnetospheric Processes (COMP) focus group will hold 2 stand-alone sessions and 2 joint sessions.

COMP Session 1 (10:30–12:00 Monday, June 12, Rm A)
Exploring the parameter space of magnetospheric physics
10:30   Overview of FG
10:40   Scene Setting Talk: magnetospheric dynamics and reconnection (Dan Gershman)
10:55   Grant Stephens: magnetic field modeling of Mercury, Earth, & Saturn
11:05   Ryan Dewey: Mercury's dawn-dusk magnetotail asymmetries and their relationship with magnetic activity
11:15   Xuanye Ma: Review of the KHI at the different planets

Open discussion: what are the big questions that can be addressed by exploring the vast physical parameter space within our solar system? (Co-chairs, Fran Bagenal, Bob Lysak)
11:25   Some elements to consider: Modeling capabilities; maturity of topic & data sets; relevance to comparative planetary needs/topics
11:55   Summary and future endeavors

COMP Session 2: MPEC-COMP Joint Session (10:30–12:00 Tuesday, June 13, Rm A)
13:30   Opening remarks
13:40   Bob Lysak: MI-coupling w/ emphasis on comparative processes between Earth & Jupiter
