Background
About the Data System (Purposes, Audience)
Emissions Modeling Framework (EMF) is an “expert system” software tool for EPA staff and contractors involved in emissions modeling. “Emissions modeling” is process of converting emission inventory data from its raw form to the forms needed by air quality models used to predict ozone, particulate matter, and hazardous air pollutants in the ambient air. This software is needed to improve efficiency and quality control of in-house and contractor emissions modeling and to provide transparency and data access to those who need information about the work of those modelers. Additionally, we anticipate making this software available to those outside of EPA so that they can have a copy of this same tool; these users would not interact with the EPA system, but rather have their own system installed at their location.
The software is a client-server application based on a three-tier architecture (see http://www.sei.cmu.edu/str/descriptions/clientserver.html). The three tiers are (1) the user interface client, (2) a database management layer, and (3) a middleware layer between the other two tiers that is used to implement the business logic of the software application. This architecture is needed to support the requirement that both data and a set of compute servers be shared among a set of users. The EPA installation of the software has user access only from inside the EPA/RTP firewall.
The EMF provides integrated quality control processes to foster high quality of emissions results, data handling, organization of data in a central database server, tracking of emissions modeling efforts, and real-time accessibility of information. A user interface will allow non-experts to access emission modeling capabilities. The interface will be able to facilitate various activities related to emissions modeling in addition the computation of emission inputs for air quality models. Such activities include 1) the acceptance of new EPA-provided data into the system with appropriate quality control and tracking; 2) set-up and execution of emissions modeling for air quality modeling applications; 3) quality assurance of emissions modeling results; 4) reporting and archiving of reports of emission inventory data; and 5) accessing projection and control information that is used for creating future-year emissions estimates.
