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

[Shim, Ja Soon (GSFC-674.0)[CATHOLIC UNIV OF AMERICA]]

Dear Colleagues,

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.

Topics for discussions and tentative agenda:

1.  Modeling neutral density/satellite drag during storms
        •  Tidal mixing effects on neutral density, Tim-Fuller Rowell (CU/NOAA SWPC)
         •  Neutral density variability driven by geomagnetic forcing: Global Joule heating index, Mariangel Fedrizzi (CU/NOAA SWPC)
         •  Improvement in modeling of neutral density at high altitude, Eric Sutton (AFRL)
         •  Ensemble Assimilation Using First-Principles Models: A Tool for Three-Day Space Weather and Satellite Drag Forecasts, Marcin Pilinski (ASTRA)

     Discussion
        •  Metrics selection relevant drag study
                    i. Definitive orbits vs derived neutral density from orbit determination for model-data comparison
                   ii. Point vs averaged density
         •  Possible sources of data at different altitudes
         •  How to Improve density prediction?
                    i. Capturing small scale structures during storm
                   ii. Prediction of geomagnetic indices
                  iii. Alternative geomagnetic indices
         •  How to Improve physics-based model neutral density at high altitude?
         •  Ideas on linking thermospheric models to orbit propagators at CCMC

2.  Regional TEC study
         •  Status of regional TEC study
      Discussion
         •  Data preparation for model-data comparison

Please let us know if you have suggestions or comments.
We look forward to seeing you at the workshop.

Best Regards,

Masha Kuznetsova
