A comprehensive modal emissions model for light-duty vehicles developed through the National Cooperative Highway Research Program (NCHRP) Project 25-11. The CMEM model and associated Vehicle Emissions Data Set is now available on CD-ROM.
See CMEM for more information.
An experimental and modeling study to reduce uncertainties in atmospheric ozone impacts of architectural coatings VOCs. The focus of this project was Texanol® (isobutyrate monoesters of 2,2,4-trimethyl-1,3-pentanediol), which is widely used in water-based coatings, and various hydrocarbon solvents representative of those used in solvent-based coatings.
See Evaluation of Atmospheric Impact of Selected Coatings VOC Emissions for more information.
Engines used in heavy-duty trucks are certified in laboratories and separate from the truck chassis and the "real world" in which they operate, because most diesel engines are designed to work in multiple applications. This approach leads to significant uncertainties in estimating the actual emissions that diesel engines produce under "real-world" operating conditions.
In response to these uncertainties, the U.S. Environmental Protection Agency and other research organizations have attempted to develop systems capable of measuring emissions from heavy-duty vehicles while on the road, or under conditions representative of "real-world" driving.

UCR IntelliShare is a research program that was established in March 1999 at the University of California, Riverside. This research testbed system has been set up for evaluating intelligent carsharing among multiple stations located on and near the UCR Campus.

The objective this EPA-funded project is to develop an environmental chamber facility that is needed for studies of photochemical air pollution formation under more realistic conditions and with more comprehensive measurements than previously has been possible. This facility will then be employed for evaluating gas-phase and gas-to-particle atmospheric reaction mechanisms, for determining how best to use ambient measurement data for predicting effects of control strategies, and for evaluating the reliability of ambient measurement instrumentation.

SELEV, in cooperation with the U.S. EPA, state agencies, and auto and oil companies, is examining the impacts that a new generation of conventional and alternative-fuel vehicles will have on air quality. We are studying the actual operations of vehicles and the makeup of the in-use fleet to understand when and where pollutants are produced. The impacts on local and regional air quality are profound.
See SELEV: Study of Extremely Low Emission Vehicles for more information.
The Western Regional Air Partnership (WRAP) has implemented a regional planning process to provide the necessary technical and policy tools needed by states and tribes to comply with the Clean Air Act requirements. As part of this effort, the WRAP has established a Regional Modeling Center (RMC) at the University of California, Riverside (UCR) with assistance from ENVIRON Corporation and the University of North Carolina.
