3. 2016 GEM-CEDAR: Testing proposed links between mesoscale auroral and polar cap dynamics and substorms Focus Group
------------------------------------------------------------
From: Kyle Murphy, Toshi Nishimura, Emma Spanswick, Jian Yang (toshi at atmos.ucla.edu)

The Substorm-Aurora-Polar Cap Focus Group (FG) discusses connections between auroral structures and their magnetospheric counterparts prior to substorm onset for bringing a potential closure to the question of substorm triggering. To make this FG activity successful, it is important to bring all substorm experts and to have community-wide discussions. Thus we encourage everyone interested in substorms to attend our sessions and bring your expertise into our focus group activity.

Session 1. Joint with Reconnection FG (Mon 4:00-6:00pm)

We will discuss the following topics:

-- Ionospheric signatures of magnetopause reconnection and FTEs
-- Possible dayside-nightside coupling
-- The role of the ionosphere in transient day- and night-side reconnection-related processes

Session 2 and 3. Event discussion (Thu 1:30-3:30pm and 4:00-6:00pm)

Three experts of substorms have analyzed the same events and will present their interpretations. We will have discussions for understanding key features prior to substorm onset and their M-I coupling. Contributed talks will be placed flexibly for facilitating discussions.

A. Event presentations
by Larry Lyons, Larry Kepko and Tony Lui

B. Contributed talks
Richard Wolf: K-H instability and interchange stability in a growth-phase arc
Tony Lui: BBF-substorm connection
Eric Donovan: Evolution and mapping of substorm onset arc
Shin Ohtani: PBI-polar cap connection
Misha Sitnov: Distinguishing roles as triggers of the substorm instability and drivers
Larry Kepko: Statistical analysis of substorm onset and auroral streamers

Session 4. Auroral streamer challenge (Fri 4:00-6:00pm)

5. 2016 GEM-CEDAR: Joint CEDAR/GEM Session: Geospace Empirical Models Tutorials
------------------------------------------------------------
From: John Emmert, Dan Weimer, Dieter Bilitza (dweimer at vt.edu)

Dear Colleagues,

We invite you to attend the Workshop “Geospace Empirical Models” on Thursday, June 23, 1:30-3:30 PM, in the Peralta/Lamy rooms of the Santa Fe Convention Center.

Workshop Description:

Empirical models, which usually incorporate key physical constraints, provide several critical functions in geospace science and space weather. Scientifically, they represent the climate of the geospace system, where climate is defined as the mean response of an environmental system to external and internal forcing, including short-term forcing. Empirical models’ encapsulation of the observational record of the geospace system provides insight into the physical mechanisms underlying the system’s response and serves as a stringent benchmark for validating first-principles models. Empirical models are widely used for space weather prediction, initial and boundary conditions, a priori estimation for measurement retrieval, and background conditions for wave propagation. This workshop will provide tutorials on major empirical models that are used in the geospace community, including NRLMSIS, HWM, IRI, and the Weimer high-latitude electrodynamics model. Each model’s formulation and physics, assimilated data, recent development, operation, and limitations will be discussed. Abstracts and more details on the workshop may be found at
 http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:Geospace_Empirical_Models#Justification_for_the_workshop.

NOAA’s Space Weather Prediction Center and our partner agencies, the U.S. Air Force, NASA Heliophysics Division, and NSF Geospace Section invite you to attend a “Space Weather: Operations to Research (O2R) Workshop” in Boulder, CO on August 16-17, 2016. 

The goal of this workshop is to gather community input for defining the capabilities needed to realize space weather O2R objectives in response to the National Space Weather Action Plan. The meeting will facilitate discussions on O2R within the broad community, including government agencies, academia, private enterprise, and space weather customers.

Panel/audience discussion will be on topics related to methods to improve operational models, tools and products including: access to operational models and data for developing and testing improvements funding opportunities to support these activities and communicating forecaster and user experience regarding the limitations of current capabilities.
