Here you will find the schedule for our sessions at the upcoming summer GEM workshop in Santa Fe. Approximate times of presentations are provided as a guide, but note these may change throughout the week or during the sessions.

Wednesday 26/06/2019 - UMEA/DAYS/IHMIC 10:30 - 12:00

Room: Santa Fe

Chair: Thomas Elsden

Theme: To consider the ULF wave response to dayside transients with different temporal/spatial scales and asymmetries.

Goals/topics:

  1. How are ULF wave properties affected by asymmetries in the upstream driver? What modelling/observational work is required to answer this?
  2. Further, how then do the resulting ULF wave asymmetries impact the M-I system?
  3. How does the 3D structure of dayside kinetic phenomena (e.g., spatial scale of magnetopause disturbance, location relative to magnetic equator) affect the ULF response in different hemispheres/LT sectors?
  4. Can we use magnetospheric observations to determine the size (localized vs global) of a dayside transient? Is the response well-enough understood?

Wednesday 26/06/2019 - DAYS/BSH 13:30 - 15:00

Room: Lumpkins Ballroom South

Chair: Andrew Dimmock

Theme: Discuss new studies of key kinetic processes which are important to both the bow shock and dayside region.

Goals/topics:

  1. transmission of transients/waves through the shock,
  2. impact of shock processes on the downstream region,

Thursday 27/06/2019 - RX/DAYS 13:30 - 15:00

Room: Lumpkins Ballroom South

Chairs: Rick Wilder and Ying Zou

Theme: Magnetic reconnection itself is one important dayside kinetic process and it is closely related to other kinetic processes, including waves and turbulence. This session tries to understand fundamentals of dayside reconnection.

Goals/topics:

  1. What are the characteristics of magnetic reconnection on the dayside?
  2. What role does reconnection play in forming various dayside transients?
  3. What are the new approaches/opportunities of studying magnetic reconnection?
