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 forecasting training

The latest SW REDI forecaster training (in June of 2019) acquainted participants with the basics of space weather forecasting via workshops and hands-on forecasting exercises.

CCMC support for Space Weather school in Argentina

CCMC is supporting a week-long school "Towards Future Research on Space Weather: Concepts and Tools" which is hosted by Towards Future Research on Space Weather Drivers Conference held in San Juan, Argentina, July 2 - 7, 2019.

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.

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:

  • July 9, 2019

    The instant-run NRLMSISe00 model was reported to return NaN at the exact altitude of 32.5 km (interface altitude between lower statosphere and troposphere and the upper stratosphere). The Fortran source code nrlmsise00_sub.for has been modified at line 213 to include the exact altitude of 32.5 km to the lower stratosphere to close the coverage gap. C sources of the model have been updated by developer Dominik Brodowski (the files at CCMC are current as of July 10, 2019).
  • June 27, 2019

    Runs-on-Request for the stand-alone CIMI ring current and radiation model (inner magnetosphere domain) now include the option to run without a plasmasphere.
    Runs performed with CIMI before always included a plasmasphere after 5 hours of simulation (3 hours after a run's requested start time).
    New run requests will feature a 7-hour warmup phase (increased from 2 hours) with the (optional) plasmasphere being added after 5 hours to run for 2 hours before reaching the start date and time of a run request.
    Plasmashere density outputs are now available as N_ps in online visualizations. For updated information on quantities written by the Fok models (Fok-RC, RBE, CRCM, CIMI) please refer to the RC_quantities.php page.
  • June 25, 2019

    The runs on request submission for the inner magnetosphere domain has been updated for two models:
    CIMI: The 2019/05/03 version of CIMI has been added to the request system.
    VERB: Users can now define their own Kp time series instead of using observations and they can specify outer boundary (at L*=7) flux scaling values instead of using GOES observations.
  • May 28, 2019

    The ap.dat file used by NRLMSISe00 instant runs was missing data from May 1, 2018 through September 30, 2018 causing requests for dates after April 30, 2018 to be invalid and the model to fail for dates after Oct. 15, 2018.
    The data file was corrected and the valid end date for the request interface was set to March 17, 2019. The date reflects data available through April 30, 2019 and allowing for the calculation of the 90-day average of F10.7 by the model (subtracting 44 days from the last date).
  • May 21, 2019

    Polar plots of CTIPe, USU-GAIM and IRI outputs may have become cut off at the dawn-dusk line in each hemisphere starting with the second frame of a movie request. The readers for these models have been corrected to avoid this problem in the future.
    In addition, polar plots with continents are now available for these models.
  • May 20, 2019

    In online visualizations of IRI request runs, the He+ number density (N_He+) was erroneously named the same as the electron density (N_e). Thus, values of N_He+ showed up in plots instead of N_e.
  • May 13, 2019

    Two parameters for the instant-run IRI-2016 model were changed to match defaults used by the 2012 model version: The "auroral boundary" option is now set to "ON" and "E-peak auroral storm model" is set to "OFF". 3-hour Kp values are only calculated (from AP values) when the "auroral boundary" parameter is ON.
