Modelers, data providers and users of space weather models are invited to participate in the GGCM Metrics & Validation Focus Group and CEDAR-GEM Modeling Challenge Sessions scheduled back-to-back during the GEM Mini-Workshop to be held on Sunday, December 4th 2011 in the Westin San Francisco Market Street hotel located at 50 Third Street (3rd floor, Franciscan II Room).
Topics for discussions and tentative agenda:
GGCM Metrics & Validation Focus Group (12:00 pm - 2:00 pm)
- Brief review of action items
- Operational geospace model validation.
- Naming conventions for model output files.
- Auroral oval boundaries metrics study
- Collaboration with other GEM Focus Groups. Ideas for future projects.
CEDAR-GEM Modeling Challenge (2:30 pm - 4:30 pm)
- Poynting Flux/Joule Heating metrics study
- Role of drivers on ionosphere model results
- Global TEC/NMF2/HMF2 metrics study
- Climatology study (Nov 21 2007 to Jan 20 2008).
- Preparation for 2012 Summer Workshops
Modelers are invited to join the Modeling Challenge. Details of the GEM-CEDAR Modeling Challenge and instructions on how to participate can be found at the CCMC Challenge Website: http://ccmc.gsfc.nasa.gov/challenges/GEM-CEDAR/. A list of six selected events, lists of physical parameters and available measurements, model output file formats for each metrics study, and submission instructions can be found at the "GEM-CEDAR Metrics Suite" link (http://ccmc.gsfc.nasa.gov/challenges/GEM-CEDAR/suite.php).
For the new metrics studies (Auroral Oval Boundaries, Poynting Flux/Joule Heating and Global TEC/NMF2/HMF2) to be discussed at the Mini-Workshop it was agreed to focus first on two priority events:
E.2006.348: 2006/12/13 00:00 UT – 2006/12/16 00:00 UT (TEC/NMF2/HMF2, Role of Drivers) E.2005.243: 2005/08/31 10:00 UT - 2005/09/01 12:00 UT (Auroral Oval, Poynting Flux/Joule Heating, Role of Drivers).
The TEC/NMF2/HMF2 Challenge is the first metrics study for the global time-dependent observational data sets. Model output results will be compared with GPS and COSMIC data in eight 5 deg. geographic longitude sectors with 5 deg. resolution in latitude from -90 to +90. First priority drivers for ionosphere models areWeimer 2005 and AMIE.
For Auroral Oval study modelers are requested to submit poleward and equatorward boundaries locations with 1 hour local time resolution (24 points for each boundary for each time step). Notes on how auroral boundaries are defined from observations prepared by Y. Zheng (yihua.zheng at nasa.gov) can be found here: http://ccmc.gsfc.nasa.gov//RoR_WWW/presentations/boundary_options.pdf.
Joule heating in the ionosphere can be calculated as a height-integrated quantity using the Pedersen conductance (Sigma_P in mho) and the height integrated ionospheric current density J=sqrt(J_x^2+J_y^2+J_z^2) (in A/m): Wdiss = J^2/Sigma_P (in W/m^2). These quantities are typically provided as output by the ionospheric electrodynamics (IE) models or IE components of coupled models. A satellite's geomagnetic longitude and latitude along its trajectory (see, e.g., http://ccmc.gsfc.nasa.gov/challenges/GEM-CEDAR/satellite_traj_mag/spc_DMSP_E.2005.243.txt) is used to obtain the local value of Wdiss. For questions/comments/suggestions on Poynting Flux/Joule Heating study please contact Lutz Rastaetter <Lutz.Rastaetter at nasa.gov> and Delores Knipp <delores.knipp at gmail.com>.
To be included in the first round of Auroral Oval Boundaries, Poynting Flux/Joule Heating and Global TEC/NMF2/HMF2 metrics studies -- please submit simulation results for the first priority events prior to the Fall AGU. For questions/comments/suggestions on Global TEC/NMF2/HMF2 please contact Ja Soon Shim <jasoon.shim at nasa.gov> and Barbara Emery <emery at ucar.edu>.
In support of simulation results analysis modelers are requested to submit time series for all physical parameters in the list http://ccmc.gsfc.nasa.gov/challenges/GEM-CEDAR/studies.php including the Joule heating integrated over each hemisphere in GW and cross polar cap potential in northern and southern hemispheres. Submissions for all six selected events are also encouraged.
