Community Coordinated Modeling Center 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.

International Forum for SW Capabilities Assessment

Take part in the International Forum for Space Weather Capabilities Assessment by joining a working team. The forum aims to address the challenges in model-data comparisons and evaluate the current state of space environment predictive capabilities. >>Forum info | Forum TEAMS and TOPICS

Space Weather REDI bootcamp 2018

Another weeklong summer Space Weather REDI bootcamp was held June 4 - 8, 2018 at NASA GSFC. Bootcamp acquainted participants with the basics of space weather forecasting and includes hands-on forecasting exercises. Find out more about annual Space Weather REDI Bootcamps.

CCMC at the 14th European Space Weather Week

Three working teams (3D CME Kinematics, CME arrival time, IMF Bz at L1) from the International Forum for SW Capabilities Assessment lead Topical Discussion Meetings at the 14th European Space Weather Week: Advance Predictions of Solar Wind Conditions at L1: Quantifying Performance. (agenda and materials). The radiation working teams were involved in a Topical Discussion Meeting: How to assess space environment models’ capability in satellite impact analysis. The ionosphere working teams were involved in Topical Discussion Meetings: Assessment of ionospheric prediction capabilities: challenges in data-model comparisons, Atmospheric Effects topical group meeting.

CEDAR Grand Challenge

CCMC is supporting the CEDAR Grand Challenge: Storms and Substorms Without Borders (SSWB). The CEDAR Grand Challenge Session was held in June at the 2017 CEDAR Workshop in Keystone, CO.

CEDAR-GEM Modeling Challenge

CEDAR-GEM Modeling Challenge Session was held in June at the 2017 CEDAR Workshop in Keystone, CO.

Mid-Tail Modeling Challenge

The CCMC has begun work on a modeling challenge to assess global MHD models' capability to predict large-scale and meso-scale dynamics of the mid-tail at 60 RE in response to the solar wind/IMF changes. Background information and presentations from the mid-tail modeling challenge session at the 2016 GEM Summer Workshop are available.
Find details here

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.

New in CCMC collaborations

New CCMC service: DONKI webservice API

New DONKI webservice API is now available for anyone who wants to obtain space weather events info stored in our database! Space Weather Database Of Notification, Knowledge, Information (DONKI) is an on-line tool for space weather forecasters, scientists, and the general space weather community. >>About Space Weather Database | DONKI webservice API | iSWA webservice API

SEP Scoreboard

CCMC is in the planning phase of a community "SEP scoreboard" together with BIRA-IASB and the UK Met Office. The scoreboard will show SEP forecasts from different types of models side-by-side. Click here to learn more or to join the planning.

Flare Scoreboard

CCMC, together with the UK Met Office, has developed the beta version of the community "flare scoreboard" which shows probabilistic flare forecasts from a variety of models. Click here to learn more.

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:

  • Apr. 17, 2019

    Run-on-Request outputs of stand-alone CIMI simulations using the run_timeseries.cgi interface always returned electron fluxes for a given simulation run request. The interface has been updated to properly support CIMI results and render proton and oxygen ion outputs when the respective visualization link was followed for the ion species.
    The support in the timeseries visualization of CIMI outputs in SWMF simulations with CIMI inner magnetosphere is still being developed.

    A glitch in publication caused results from runs submitted between Oct. 18, 2018 through Nov. 24, 2018 to become masked by newer runs. The problem was introduced on Feb. 5, 2019 and has been corrected.
    Model name and run name listed at the top of visualization forms should match your run name and requested model. If the model or run name are wrong, contact us so we can correct the CCMC visualization links provided with your run's web page.

  • Apr. 2, 2019

    The run submission procedure for the Weimer, Cosgrove-PF, and Ovation-Prime ionosphere models caused the last solar wind density value of the input time series to be listed as the first density value in run result pages. The same bug was also found in run requests of inner magnetosphere models (RCM, CIMI, Tsyganenko).
    The issue has been corrected and all affected runs have been reprocessed to list the correct parameter in the database.
    The model themselves used the correct solar wind values and results were not affected.
  • Feb. 26, 2019

    Run-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, 2019

    SWMF 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, 2019

    Ground 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, 2019

    SWMF 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, 2019

    The 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.
