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.
- We provide, to the scientific community, access to modern space research models
- We test and evaluate models
- We support Space Weather forecasters
- We support space science education
New in CCMC collaborations
- The CCMC is collaborating with ESA’s SPace ENVironment Information System SPENVIS team to interlink space weather models and tools hosted by each group.
- CCMC staff is now collaborating with the University of Michigan team on real_time simulation of the solar atmosphere and inner heliosphere using AWSoM-R global MHD model developed at the University of Michigan.

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:
Feb. 26, 2019Run-on-Request simulations using the SWMF magnetosphere model have been using a numerical parameter UseFullCurrent=True in the ionosphere electrodynamics module. This choice may cause unphysical oscillations in the ionospheric current system and in ground magnetic disturbance outputs.
The SWMF developers recommend setting the parameter to False. The change has been applied to runs requested on Feb. 25 and Feb. 26, 2019 and will apply to all future SWMF magnetosphere run requests.
Feb. 25, 2019SWMF magnetosphere requests can either use the Rice Convection Model (RCM) (with or without the Radiation Belt Electron (RBE) model) or the Comprehensive Inner-Magnetosphere Ionosphere (CIMI) model (covering ring current electron and ion and radiation belt electron energies).
The older Comprehensive Ring Current Model (CRCM) has been removed from the options.
ACE realtime solar wind data have been missing since Dec. 19, 2018 due to an operation system configuration change. The data stream has been restored and data are again available (subject to daily gaps).
Feb. 22, 2019Ground magnetic perturbation results from the post-processing tool CalcDeltaB were accidentally multiplied by a factor of 50 during visualization.
The error has been corrected and existing CalcDeltaB runs do not need to be redone.
Feb. 20, 2019SWMF Magnetometer grid data results generated by the 2018/05/25 version of SWMF exhibit irregularities at the magnetic poles. The north and east components may change sign from one output time to the next due to a flaw in the numerical computation of the rotation matrices used. Results away from the poles are correct and visualizations should avoid the poles (by moving away at least a grid space in latitude).
CalcDeltaB results at the magnetic poles do not show these sign flips and thus are not affected by this problem.
Feb. 6, 2019The time series visualization (via run_timeseries.cgi) now accepts user-uploaded satellite trajectory files in addition to the trajectories available via SSCWeb. Text files with 10 data columns headed by "Year Month Day Hour Minute Second ms" followed by the names of the three spatial coordinates (such as " X Y Z" or " lon lat height") are being accepted. Trajectory data are assumed to be in the model coordinate system.
The SSCWEB satellite inventory used for time series extractions and run on request submissions has not been updated since Aug. 19, 2018. The update was performed by hand at 4:25 PM Eastersn (9:25 PM UT) on Feb. 6, 2019.
Nov. 29, 2018The global magnetosphere run request system may have incorrectly selected CRCM instead of RCM as the inner magnetosphere model in SWMF run requests. The submission system has been patched to select the correct ring current model.
Nov. 26, 2018DSCOVR L2 data (H0/mag, H1/fc (Faraday Cup)) are now available as input for magnetosphere request runs., either through the input file generation page or the magnetosphere run request system (run requests of inner magnetosphere models and empirial models of the ionosphere also offer DSCOVR L2 inputs as of Nov. 29).
Nov. 8, 2018Solar wind data from the WIND spacecraft that can be used for various run-on-request run submissions have been updated through October 27, 2018.
Data from earlier years have been updated to the latest version available at CDAWEB.
Nov. 6, 2018The start page of the magnetosphere model run submission was modified to explain that the inner magnetosphere model selections (RCM and RBE or CRCM) apply to any of the SWMF/BATSRUS model versions listed before.
