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.
ULF Modeling ChallengeThe CCMC has begun work on a modeling challenge to assess global MHD models' capability to specify the ULF wave power distribution in the inner magnetosphere. Background information and presentations from the ULF modeling challenge session at the 2015 GEM Summer Workshop are available.
Magnetopause Modeling ChallengeWork on the magnetopause modeling challenge resumed by applying methods developed for the Operational Geospace Model Validation (event-based skill scoring). In addition work has begun to identify events with multiple magnetopause crossings, either by a string of satellites (Cluster or Themis) or of satellites from different missions (DoubleStar, Themis, Geotail, ...). We selected events with quiet time solar wind or with shock impacts onto the magnetosphere.
- 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
Flare Scoreboard Planning
CCMC, together with the UK Met Office, is in the planning phase for the development of a community "Flare Scoreboard" which will show probabilistic flare forecasts from a variety of models. Click here to learn more about the flare scoreboard and to join the planning.
• submit their forecast in real-time
• quickly view all forecasts at once in real-time
• compare forecasting methods when the event has arrived
Highlighted CCMC services
- MAGIC: new magnetogram processing suite of tools.

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. 3, 2016Database access for request run searches was unavailable since the 28th of January. The problem has been corrected.
Nov. 20, 2015The file system holding Runs-on-Request model output data experienced serious problems leading to disconnection from the web server. This occurred from about 5 PM on Nov. 19, 2015 through 1 PM on Nov. 20 Eastern United States Standard Time (UT -5 hours).
Nov. 18, 2015Overview movies of simulation runs of the Magnetosphere (at X=0, Y=0, Z=0) and the ionosphere electrodynamics (ΣP, ΣH, Φ+V and JR+J in both hemispheres) are now limited to 250 frames so that they display more reliably. Movies showing long simulations may only represent a subset (say, one of every 10) of available output time steps.
Nov. 6, 2015Run-on-Request runs of the magnetosphere and inner magnetosphere using ACE real time data are incorrect due to missing solar wind propagation between the ACE spacecraft position and the upstream boundary position of the model. The step (usually resulting in a 30-60 minute delay) was not performed during run submission since a major redesign of the submission system back in 2012. Users who requested affected runs will be notified and runs will be marked with a validation level of (-1) indicating problems until reruns are performed. Requests submitted on or after Nov. 6, 2015 should be correct.
Oct. 6, 2015Images of real time WINDMI model results may have shown incorrect Dst values for the last hour that data were available. This has been occurring during the first 9 calendar days of each month. The problem has been corrected by preserving the exact format of the real-time Dst data instead of eliminating the leading blank character in front the single-digit day number.
Sep. 10, 2015TEC values in TIE-GCM model outputs may have been rendered in units of cm-2 or without units at all. The visualization has been updated to render values in TEC-units (TECU) after multiplying numerical values with 10-12.
QJOULE_INTEG values in TIE-GCM model outputs were rendered with an incorrect conversion factor (1/100) applied. The unit provided by the model (erg/cm2/s) is identical to the displayed unit (mW/m2) and no conversion of values is needed.
Aug. 24, 2015ACE L2 and WIND solar wind data have been updated and are available through 2015/04/13 and 2015/08/09, respectively.
Aug. 19, 2015Real-time Dst index data in WINDMI real time plots ceased on July 30 due to a reorganization of archive directories at the CCMC. The missing data also affected instant runs of WINDMI and run requests of other models that may use Dst as inputs or for comparisons (for run end dates after 2015/07/30).
The data feed has been restored and the whole Dst data archive has been updated with currently available final data (through the end of 2011) and provisional data (for the years of 2012 and 2013 and the month of March 2015).
Aug. 17, 2015The Quantity O/N2 (ratio of Atomic Oxygen over Molecular Nitrogen number densities) was erroneously listed in online visualizations of CTIPe outputs as "N/O2". All the runs have been reprocessed to show the correct variable.
The magnetic field polarity in ENLIL heliosphere model runs (represented as "polB") was not properly recognized in runs starting in 2015 due to a modification in the model's output files. This prevented the magnetic field from being reversed in regions of negative polarity and caused visualizations to fail when the magnetic polarity variable was requested. The issue has been corrected.
