CCMC mission statement

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.


Space Weather REDI Bootcamp

SAVE the DATE: the next Space Weather Bootcamp will be held on June 6-17, 2016. The past Bootcamp in summer of 2015 proved to be a great success, with more than 50 participants from many countries and diverse backgrounds (view presentations and assignments).

Space Weather training at Kennedy Space Center

The CCMC organized a three-day space weather training at Kennedy Space Center in February of 2016. The training was attended by 32 people, including NASA KSC and NOAA weather service staff, as well as Air Force launch officers at Cape Canaveral.

Introduction to Space Weather School

The CCMC supported the " Introduction to Space Weather: Concepts and Tools " School hosted by the " Science for Space Weather Workshop" held in Goa, India, in January 2016. This one-day training was followed by interactive programs and demo sessions throughout the week of the workshop.

CEDAR Grand Challenge

CCMC has supported the CEDAR Grand Challenge: Storms and Substorms Without Borders (SSWB). The CEDAR Grand Challenge Session was held last December 13, 2015, during the 2015 mini-GEM Workshop in San Francisco.

CEDAR-GEM Modeling Challenge

Modelers, data providers, science and operational users of space weather models were invited to participate in the CEDAR-GEM Modeling Challenge Session at the 2015 mini-GEM Workshop last December 13, 2015 in San Francisco.

ULF Modeling Challenge

The 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.
Find details here

Magnetopause Modeling Challenge

Work 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.

4th Annual Student Research Contest

The Community Coordinated Modeling Center and National Science Foundation are pleased to announce the results of the fourth annual CCMC Student Research Contest. Find out more

New Horizons Flyby Modeling Challenge

CCMC has initiated a community-wide effort to provide solar wind modeling support for the New Horizons, providing computer simulations of the near Pluto Solar wind environment for the time period of the New Horizons Spacecraft flyby. Click here to learn more about the project and to participate in the challenge.

CCMC Services

  • 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.

CME Arrival Time Scoreboard

CME arrival time predictions from the research community The CME Scoreboard is a research-based forecasting methods validation activity which provides a central location for the community to:
  • submit their forecast in real-time
  • quickly view all forecasts at once in real-time
  • compare forecasting methods when the event has arrived

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, 2016

    Database access for request run searches was unavailable since the 28th of January. The problem has been corrected.
  • Nov. 20, 2015

    The 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, 2015

    Overview 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, 2015

    Run-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, 2015

    Images 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, 2015

    TEC 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, 2015

    ACE L2 and WIND solar wind data have been updated and are available through 2015/04/13 and 2015/08/09, respectively.
  • Aug. 19, 2015

    Real-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, 2015

    The 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.
