RIVERSIDE, Calif. (www.ucr.edu) – Portable Emissions Measurement Systems (PEMS) are revolutionizing how we measure, report, and enforce fuel and efficiency standards to ensure emissions compliance from all types of vehicles while they are in use. By dramatically increasing the amount of data available and the types of compliance testing that can be accomplished, PEMS are a key resource in addressing some of today’s most pressing energy and air quality challenges.

The University of California, Riverside’s Portable Emissions Measurement Systems (PEMS) Conference and Workshop is the only worldwide conference dedicated to reviewing the evolving state of research, applications, and new regulations for these systems. This year’s conference will be held from 7 a.m. to 5 p.m. March 17 and 8:30 a.m. to 1:30 p.m. March 18 at the Center for Environmental Research and Technology (CE-CERT), which is part of UCR’s Bourns College of Engineering.

The keynote speakers will be Ed Nam, director of the Air Quality Modeling Center in the Office of Transportation and Air Quality at the U.S. Environmental Protection Agency; and Matthew Thornton, principal engineer/group manager at the National Renewable Energy Laboratory. Also speaking is Daniel Carder, director of the Center for Alternative Fuels Engines and Emissions at West Virginia University, whose research team first discovered elevated levels of nitrogen oxides in Volkswagen diesel vehicle emissions.

Now in its 6th year, the annual conference features in-depth discussions about the state of PEMS technology and the future of the field. More than 200 international participants from government, industry and academia have attended in the past, and more are expected this year as the interest in portable emissions testing of light-duty vehicles continues to grow.

“Since its inception more than 20 years ago, CE-CERT has served as an honest broker, working together with industry, researchers and regulators to develop impactful solutions. One such solution is the development of PEMS systems. PEMS are a unique set of tools that can be used to ensure we are achieving adequate energy and air quality metrics to protect human health and the environment,” said Kent Johnson, associate research engineer at CE-CERT and the conference organizer.

Discussion topics will include: What accuracy allowance is needed to identify deviations from regulation? Are either certification or on-vehicle measurements needed or both? How to manage large datasets from a PEMS unit or from a community of low-cost PEMS’ users to advance our understanding? Do we need better education, applications, or protocols? What is the future for inexpensive micro PEMS/sensors, or new measurement units for particle number?
