November 6, 2017 – GCAM 4.4 has been released.
Detailed documentation of the GCAM is available at the GCAM Wiki, including a Getting Started with GCAM page. See also the GCAM Community web page. GCAM releases are available for download on Github including all source code, executables, and input data to run the model.
GCAM and the GCAM Model Interface are made available under the terms of the ECL open source license version 2.0. Portions of this software incorporate other open source projects that are subject to their own open source licenses.
GCAM users are requested to follow the following guidelines.
A) Please cite the following two reference when publishing results obtained with GCAM:
Kim, S.H., J. Edmonds, J. Lurz, S. J. Smith, and M. Wise (2006) The ObjECTS Framework for Integrated Assessment: Hybrid Modeling of Transportation Energy Journal (Special Issue #2) pp 51-80.
B) Researchers are welcome to make any changes they like for their own research interests. However, any revised version, with altered input data or model code, must be identified not as GCAM but as GCAM-xxxx. For example, the GCAM version that has been customized with input data specific for India is referred to as GCAM-IIM (for India Institute of Management).
If you have made model changes (code or data) that you feel may be useful to the broader GCAM community please see CONTRIBUTING instructions on the GCAM Github repository.
C) We would appreciate a notice of publications using GCAM results. You can send a notice to one of the GCAM model contacts listed on the Main GCAM Model webpage.
Users are encouraged to sign up for the GCAM Community Listserv. The listserv is the primary means used for distributing information about GCAM. While we cannot promise user support, the GCAM development group makes every effort to answer queries posted to the listserv.
Alternatively users may find it more convenient to ask question on Github as an Issue (please add the “Question” Label when creating the issue). Using Github for questions provides a modern interface for tracking and searching for responses. In addition would allow for users to post relevant files which is not available through the Listserv.
