The CCMC is a multi-agency partnership to enable, support and perform the research and development for next-generation space science and space weather models.
The 8th CCMC Workshop took place last April 11-15, 2016 at Annapolis, Maryland.
Biennial CCMC community workshops are designed as opportunities for an in-depth exchange of experiences, opinions and needs between model owners, science and operational users, educators, agency representatives and the CCMC staff.
To comply with Office of Management and Budge (OMB) Memorandum M-15-13 "Policy to Require Secure Connections across Federal Websites and Web Services", CCMC will start to use the SSL/TLS Certificate issued by NASA by September 23, 2016. We are aware that Federal Common Policy CA is not in the trust store.
While using Firefox accessing CCMC websites you will get "Your connection is not secure" with an error code "SEC_ERROR_UNKNOWN_ISSUER". Please add an exception for it, while we investigate other possible solutions.

• compare forecasting methods when the event has arrived
Highlighted CCMC services
- Kameleon software: model output from different models can be stored uniformly in a common science data format. Users can request the CDF-formatted output for a CCMC run.
- MAGIC: new magnetogram processing suite of tools.
Model additions/updates at the CCMC
- New SWMF AWSoM_R (Alfven Wave Solar Atmosphere Model) offers:
- steady state ambient solar wind modeling, using Full Carrington Rotation Integrated synoptic maps (magnetograms).
- Time-dependent CME modeling, where CME is superimposed on a steady state ambient solar wind solution. The CME parameters are generated using newly introduced EEGGL (Eruptive Event Generator, Gibson and Low) tool. There is an option to choose between Full Carrington Rotation Integrated Synoptic maps (magnetograms) or QuickReduce Synoptic maps (hourly updated magnetograms).
Model Developers: Igor Sokolov, Bart van der Holst,Meng Jin, Ward Manchester, Gabor Toth and Tamas Gombosi, Center for Space Environment Modeling, University of Michigan and Lockheed Martin.
NOTE: At the time the model needs further calibration, the recommended values for parameters are not guaranteed to be the best.
- SWMF: dipole orientation and magnitude options. In an effort to expand the range of science questions that can be probed with the models hosted at CCMC, we have now expanded the range of available dipole orientations and magnitudes in the University of Michigan’s Space Weather Modeling Framework (SWMF). These new parameter ranges allow studies of for example early Earth’s and other exoplanet targets of interest. We welcome our users to explore these new CCMC capabilities and look forward to receiving your feedback.
- TIE-GCM 2.0 version is now available on Runs-On-Request
- The Drag-Based Model (DBM) tool: provides prediction of the interplanetary coronal mass ejection (ICME) expansion and its prediction of arrival at arbitrary location or preselected planet or satellite) in the ecliptic plane.
- The Kinematic Model for CME Deflection(DIPS) has been added to Runs on Request. It predicts the trajectory of a CME in ecliptic plane.
Runs on Request/Online Visualization changelog
View the log of changes/updates to the 3DView online visualization, as well as announcements regarding occasional correction/re-execution of past ROR requests. The most recent changes were:
Nov. 4, 2016Total Electron Content (TEC) from runs of the SAMI3 model is now available in the Run-on-Request visualizaion system. The two-dimensional map is best rendered at a low altitude above about 170 km (the highest points of the bottom flux tubes in the model grid).
The resolution of the plot grid used in all visualizations of Runs-on-Request results has been improved. The number of positions used is now proportional to the selected image magnification. As a result, plot grid resoluton is two times finer than before for a default-sized image and up to four times finer for twice-enlarged images.
Note: ASCII outputs are returned at a different (coarser resolution).
Oct. 27, 2016The Run-on-Request submission systems for global magnetosphere and inner magnetosphere now support solar wind inputs from the DSCOVR satellite (as applicable). Daily DSCOVR real time data have been accumulated from NOAA SWPC's solar wind data stream since 2016/07/27 when the satellite was started to be used in operations at SWPC. We added a warning that ACE realtime data after 2016/07/27 have daily gaps.
Oct. 26, 2016Runs-on-Requests of the magnetosphere now use a minimum temperature of 10000 K in solar wind inputs. Before, zero (missing) temperature data were replaced with a value too low to allow the models to run successfully. Although the solar wind temperature is not very important as a solar wind driver of geomagnetic activity, it does affect model stability in global magnetosphere simulations.
Sept. 19, 2016Runs-on-Requests for the CMIT model submitted in the future will use 2.5 by 2.5 degree resolution TIEGCM ionosphere (if requested). Before, all runs used a 5 by 5 degree TIEGCM grid.
The MIX ionosphere electrodynamics grid will be set to 1 by 1 degree resolution for runs using the quad-resolution LFM grid (106x96x128 cells). All coarser LFM grids run with 2 by 2 degree MIX resolution (as did all runs before).
Sept. 7, 2016Runs-on-Requests: The option to track satellites in Global Magnetosphere (GM) requests became unavailable on or after Sept. 2, 2016 due to a loss of a file listing satellite orbit parameters.
The file has been restored and request runs of selected GM models can again include satellite traces. Satellite positions can be visualized with the magnetosphere MHD and ionosphere electrodynamics simulation outputs.
