CEDAR email: Invitation to 2015 CEDAR Workshop “CEDAR-GEM Modeling Challenge” session

Tue Jun 23 14:26:52 MDT 2015

We invite you to participate in the CEDAR-GEM Modeling Challenge Session at 2015 CEDAR Workshop. The session will be held on Thursday, 25 June, from 10:00 am -12:00 pm at Kane 220 at the Univ. of Washington.  In the session, we will focus on “Modeling neutral density/satellite drag during storms”.

Topics for discussions and agenda

  *   Tidal mixing effects on neutral density, Tim-Fuller Rowell (CU/NOAA SWPC) (10:00 - 10:20)
  *   Neutral density variability driven by geomagnetic forcing: Global Joule heating, Mariangel Fedrizzi (CU/NOAA SWPC) (10:20 - 10:35)
  *   Improvement in modeling of neutral density at high altitude, Eric Sutton (AFRL) (10:35 - 10:50)
  *   Ensemble Assimilation Using First-Principles Models: A Tool for Three-Day Space Weather and Satellite Drag Forecasts, Marcin Pilinski (ASTRA) (10:50 - 11:05)
  *   GITM comparisons to GOCE, CHAMP and GRACE mass density data, Aaron Ridley (UM) (11:05 - 11:15)
  *   High-latitude neutral density statistics, Cheryl Y Huang (USAF AFMC AFRL/RVBXP) (11:15 - 11:25)
Discussion (11:25 – 12:00)

     *   Metrics selection relevant drag study
        *   Definitive orbits vs derived neutral density from orbit determination for model-data comparison
        *   Point vs averaged density
     *   Possible sources of data at different altitudes
     *   How to Improve density prediction?
        *   Capturing small scale structures during storms
        *   Prediction of geomagnetic indices
        *   Alternative geomagnetic indices
     *   How to Improve physics-based model neutral density at high altitude?
     *   Ideas on linking thermospheric models to orbit propagator at CCMC
“Regional TEC study”, which was initially planned to be discussed in this session, will be discussed at the mini-GEM workshop on the day before 2015 AGU fall meeting.
