PNNL is committed to making the Global Change Assessment Model (GCAM) a community tool – expanding its user community and gradually opening the development of the model to this community. A range of users across the globe are now using and modifying GCAM for their individual research needs.
Listserv: To support the emerging community of GCAM users, we have created a GCAM Community Listserve. The listserve serves as a place for conversations among GCAM users. It also serves as a vehicle for raising questions about GCAM to which other members of the community or staff at the Joint Global Change Research Institute can respond. Finally, it serves as a means to make announcements about updates or changes to the model. To subscribe to the listserve with email, please send an email to email@example.com with the email body: subscribe gcam-community . You can also go directly to the website for the listserv, which has all the functionality including posting at: https://listserv.umd.edu/archives/gcam-community.html. You do not have to be registered to view the archive on the website.
Research with GCAM: Individual researchers within and without PNNL are welcome to make any changes they like for their own research interests. However, any revised version must be identified not as GCAM but as GCAM-xxxx. For example, the GCAM version that has been customized to India is referred to as GCAM-IIM (for India Institute of Management)
2012 Community Modeling Meeting: The 3rd annual GCAM Community Modeling Meeting was held on September 18th, 19th, and 20th, 2012 at the Joint Global Change Research Institute (JGCRI) in College Park, Maryland (http://www.globalchange.umd.edu/). The meeting included sessions covering the current status of GCAM, future development directions, collaborative and other research activities using GCAM, a tutorial on using GCAM, and user training. For the first time the 2012 GCAM Community Modeling meeting was held in parallel with the GTSP (Global Technology Strategy Program) Technical Workshop on September 19th and 20th at JGCRI. The Technical Workshop covers ongoing, cutting-edge research in integrated assessment modeling from researchers at JGCRI as well as members of the GCAM community and other collaborators.
Presentations from the 2012 GCAM Modeling Community Meeting are available at the agenda section of the meeting webpage.

2011 Community Modeling Meeting: On November 29 and November 30, 2011, the second meeting of the GCAM modeling community was held at JGCRI. The first day focused on an overview of the model, presentations from community members using GCAM, and a discussion of GCAM community needs. The second day included a tutorial on running and interpreting GCAM as well as hands on assistance from JGCRI staff. The agenda for the meeting and presentations are below. An informal assistance session was also held on the following Thursday.

2010 Community Modeling Meeting: On September 29 and September 30, 2010, the first meeting of the GCAM modeling community was held at JGCRI. The meeting took place over two days. The first day focused on plans for building a GCAM modeling community, an overview of the model, examples of existing work by GCAM collaborators, and plans for model development. The second day included a tutorial on running and interpreting GCAM as well as hands on assistance from JGCRI staff.
