The Environmental Modeling (E-Mod) Community of Practice (CoP) has been established for modelers (i.e., developers, users, evaluators, and those with a passion for modeling [e.g., statisticians, software analysts] - likeminded individuals) to come together as a community with an open opportunity to regularly interact with one another, form new collaborative relationships, and possibly pursue a project(s) to advance environmental modeling at the US Environmental Protection Agency (EPA or the Agency). This is a cross-Agency opportunity to learn about the exciting modeling related activities ongoing or needed within (or potentially outside of) the Agency; collaborate with colleagues to solve an issue; learn about new modeling techniques, tools, or opportunities (i.e., internal or external to the Agency); talk with individuals that use the same language, among other things.
