Community Coordinated Modeling Center Operational

From: Michael Hesse (hesse at gsfc.nasa.gov)

The Community Coordinated Modeling Center (CCMC, http://ccmc.gsfc.nasa.gov) 
is a multi-agency activity aimed at the generation of advanced space 
science models to meet space weather needs. The CCMC addresses the entire 
range from the solar atmosphere to the Earth's upper atmosphere. The CCMC 
consists of distributed computational resources and a central facility 
located at Goddard Space Flight Center. The CCMC works with the research 
community to create improved and coupled space weather forecasting models, 
and to provide community access to the output from state-of-the-art 
research models. For this purpose, as well as to facilitate model testing 
by a large number of researchers, the CCMC is now offering to the general 
research community specific event simulations on request. Initially, 
requests for runs of magnetospheric global models are being solicited. In 
the near future, solar/heliospheric and ionospheric/thermospheric 
simulations will be offered also. At the present time, runs will be 
restricted to 2 hours of real time. Model input data are to be provided by 
the requestor. Model run results will be made available to the general 
research community via our web-based interface.

Any interested individual should submit a request statement to 
request at ccmc.gsfc.nasa.gov, with a brief description of the desired 
simulation, and with contact information. CCMC staff will then contact the 
requestor for further information.

In order to select appropriate models to participate in the CCMC process, 
the CCMC steering committee is interested in guidance by the research 
community. For this purpose, the CCMC steering committee is establishing an 
informal Science Working Group, consisting of solar/heliospheric, 
magnetospheric, and ionospheric researchers to advise on CCMC policies and 
priorities. Please let us know if you are interested in participating in 
the working group activities. The expected level of effort in the working 
group is of the order of a one-day meeting a year.

Any individuals interested in CCMC Science Working Group activities should 
contact Dr. Bob Robinson (rmrobins at nsf.gov) with a statement of interest.
