Southward IMF Challenge: simulation-observation comparisons Two participating modeling teams have joined forces with observers to proceed with the analysis of the 2015-11-18 event. We’ll first hear each collaboration present their simulation-observation comparisons on five prescribed topics: magnetic field and plasma signatures, waves, magnetopause location, and X-line dynamics. We’ll then get a chance to make on-the-spot model-model-observation comparisons. Finally, each collaboration gets to present any extra findings they’ve made. When we reconvene refreshed after the coffee break, we’ll discuss the next steps of this Challenge.

[FG] Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere

Location: Zia Ballroom
Chairs: Christine Gabrielse, Drew Turner, David Malaspina, Matina Gkioulidou, Slava Merkin

We will have a panel discussion on the questions below with an aim to communicate different types of models' capabilities to answer different science questions, as well as a discussion on how we can move forward towards improved, data-informed models. We invite the audience to participate in the discussion and to provide input as to how we, as a field, can move forward to better understand how dipolarizations affect the inner magnetosphere, and/or how they are affected by the coupled magnetosphere-ionosphere system.

Panelists
Misha Sitnov
San Lu
Jimmy Raeder
Yann Kempf
Colby Lemon
Katie Garcia-Sage

Panel Questions

1) Given our current modeling capabilities, discuss which kinds of models are best at capturing which aspects of dipolarization events and their effects in the magnetosphere.

2) What determines the dipolarization scale size in different models? (e.g., physical description, boundary conditions, model input parameters, ionosphere conditions, etc.?)

3) The transition region is where both inertia and energy dependent drifts are important. No existing models treat that region correctly.

(a) How do we move forward?

(b) Or, more specifically, address the question of dipolarization front deceleration: (i) How do various models treat dipolarization deceleration as they approach the inner magnetosphere? (ii) What processes are decelerating the fronts in the models? (iii) What inner magnetosphere processes are missing (e.g. plasmasphere, complex ionospheric conductivity models) and does excluding these processes lead to different deceleration predictions?

(c) And/or address: (i) What are the relative roles of ExB, energy-dependent drifts and particle trapping in transport and energization in the transition region? (ii) To what extent are these processes adiabatic for particles of different energies? (iii) What is their overall contribution to the ring current build up?

Although the questions are focusing on dipolarization implementation into the current magnetospheric models, participation of data analysts is highly desired and encouraged in order to establish an observational framework for the models.

1530-1700: Splinter Sessions

[Joint] Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction + Modeling Methods and Validation

Dayside-Nightside Connections Challenge: a substorm triggered by magnetosheath jets? This theme echoes the second half of our FG’s name. Last summer Katariina Nykyri presented an event with great potential for community efforts: an MMS-THEMIS conjunction where timing suggests that a substorm was triggered by transient dayside magnetosheath jets. The FG has taken up the challenge and coordinated activities in preparation for the workshop.

First Chih-Ping Wang will provide an introduction to the theme by presenting an event featuring a foreshock transient propagating to the mid-tail. Katariina Nykyri will then present the challenge event. The following presentations will let us see whether DMSP, SuperDARN, and ground magnetometer observations support the hypothesis.

• Next steps of Southward IMF challenge

• Ying Zou, Introduction to Dayside-Nightside Connections Challenge

• Chih-Ping Wang, Propagation of foreshock transients to mid-tail

• Katariina Nykyri, Challenge event observations using THEMIS & MMS and simulations

• Simon Wing, Challenge event observations using DMSP

• Xueling Shi & Mike Ruohoniemi, Challenge event observations using SuperDARN

• Toshi Nishimura, Challenge event observations using ground magnetometers

• Discussion

[FG] Interhemispheric Approaches to Understand M-I Coupling (IHMIC)

1330-1500: Splinter Sessions

[Joint] 3D Ionospheric Electrodynamics and Its Impact on the Magnetosphere-Ionosphere-Thermosphere Coupled System (IEMIT) + Interhemispheric Approaches to Understand M-I Coupling (IHMIC)

*** Location: Eldorado B ***

This session is a joint session between IEMIT and IHMIC. The first three talks are about observational studies, and the last three talks are about the coupled MIT modeling. We encourage both GEM and CEDAR scientists to join the discussion.

  1. Bob Clauer: Inter-hemispheric Comparisons along the 40-degree magnetic meridian
  2. Denny Oliveira: GIC induced by interplanetary planetary shocks
  3. Michelle Salzano: A Statistical Analysis of Interhemispheric Pi1B Seasonal Variations
  4. Hyunju Connor -Solar wind dynamic pressure impact on high-latitude neutral density enhancement: OpenGGCM-CTIM results
  5. Doga Ozturk - Modeling of coupled MIT system response to solar wind dynamic pressure enhancement
  6. Kevin Pham - CMIT-IPWM one way coupling - Thermosphere impact on the magnetosphere
  7. Open discussions and walk-in presentations
