Please read conditions carefully - By accepting a CMWeb account you are agreeing to abide by the following terms and conditions. Failure to do so may result in the closure of your account.
CMWeb analyses should be treated as Official Use Only (OUO) until determined otherwise. Examples include hazard prediction maps/plots, reports, data files, GIS shapefiles, incident location or release information, or projected health effects. Users are required to protect the security of sensitive unclassified information generated by this system.
The CMWeb is designed to be a secure environment for sensitive unclassified information, but it is not designed for classified content. Classified simulations cannot be performed on this system and classified information cannot be downloaded onto the system.
This Web capability is part of a Federal computer system used to accomplish Federal functions. The CMWeb access is protected using user authentication, data encryption, digital signatures and HTTPS protocol. It is your responsibility to inform CMWeb of any security incidents that have the potential to compromise the CMWeb system.
Lawrence Livermore National Laboratory (LLNL) uses software programs to monitor this Web site for security purposes. By accessing this Web site, you are expressly consenting to these monitoring activities. Unauthorized attempts to defeat or circumvent security features, to use the system for other than intended purposes, to deny service to authorized users, to access, obtain, alter, damage, or destroy information, or otherwise to interfere with the system or its operation is prohibited. Evidence of such acts may be disclosed to law enforcement authorities and result in criminal prosecution under the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act of 1996, codified at section 1030 of Title 18 of the United States Code, or other applicable criminal laws.
We collect and maintain databases of the information you provided in requesting your account. The CMWeb system also collects and stores certain information automatically, including:
This information is used for internal purposes only, including collection of usage statistics and improvements in services. This information is not shared with anyone beyond the support staff to this Web site, except when required by computer security or law enforcement investigation.
Your email inquiries may be forwarded to another LLNL employee, who can better assist in answering your question, but will not be shared with outside agencies without your express permission.
This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory in part under Contract W-7405-Eng-48 and in part under Contract DE-AC52-07NA27344.

These model predictions are approximations and intended to be guidance, and are not final recommendations. The accuracy of any prediction will be limited by the accuracy of the input data, such as estimates of the amount of material that becomes airborne and the available meteorological data for the area and time of the incident. Plume predictions may be for a limited time period, and may change at later times if new input data becomes available. Predictions should be confirmed and refined using field measurements. Air and ground concentration may be higher than predicted by this plume model simulation due the limited resolution of this particular simulation. For actual incidents or exercises, consult incident command and subject matter experts from the appropriate coordinating agency before making any decisions based on this model prediction.
