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 training

The space weather training acquaints participants with the basics of space weather forecasting via lectures and workshops.

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.

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

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:

  • June 3, 2021

    Field or flow lines in 2D slices have been using colors that varied with the color table selected. This has been corrected by using fixed colors (blue,gree,red) that have been reserved at the bottom and top of the color table (outside of the color index range used in color contours).
  • Apr 6, 2021

    Over the last two months online visualizations ran into infinite loops causing the resulting log files to fill the space reserved for temporary image and data files. This has disabled online visualizations and instant run models such as IRI and MSISe.
    The affected subroutine has been corrected to exit when encountering an incomplete magnetosphere model output file.
  • Mar 3, 2021

    The run-on-request postprocessing tool CalcDeltaB now supports GUMICS magnetosphere simulation runs.
    GUMICS ionosphere visualizations were corrected to feature the correct unit for horizontal currents (µA/m). Also, horizontal current vector components values are now multiplied with 106 from their original units (A/m).
    In the visualization of GUMICS magnetosphere outputs, electric currents (Jx, Jy, Jz) have been added. Current densities are computed in each cell from magnetic fields available on the corners. Current densities are constant in each cell and discontinuous across cell surfaces.
  • Dec 3, 2020

    We are experiencing increased demand for visualizations (single images, instant model runs and movie requests). The demand has exceeded the capacity of the file system holding temporary files including images, ASCII output files and archive files for viewing and download.
    The file system server has been rebooted and space has become available.
    Instant run models, online visualizations and movie request are functioning normally again.
  • Nov 4, 2020

    For magnetosphere run-on-request runs timeseries outputs for model-data comparison in the Virtural Model Repository (VMR) tools were not automatically provided since March 2020 due to a script error.
    The automatic data generation has resumed and several issues were addressed.
    Default (missing) values provided by SWMF/BATSRUS when a satellite is outside of the magnetosphere simulation box are now filtered out.
  • Oct. 9 2020

    It came to our attention that some dates in 2019 were not possible in magnetosphere run-on-request submissions. An incomplete data file containing Kp, Ap and F10.7 data for 2019 was the cause. The file has been replaced with a complete version and dates after Sept. 15, 2019 can now be requested. This problem may have affected requests for models of the inner magnetosphere as well.
  • Sept. 10 2020

    Version 3.1 of the OpenGGCM model in the magnetosphere is being retired. We will only accept requests using versions 4.0 and 5.0 of the model. Existing requests as of Sept. 10, 2020 using version 3.1 will be completed as requested.
    Visualizations of MAS polytropic corona outputs in CORHEL solar-heliosphere requests failed with the plot image generated not being recognized after a plot request. The issue has been corrected and images are being displayed as ewxpected.
