PEMS 2022 - Moving Towards Onboard Sensing, Analysis, and Reporting (OSAR)

11th Annual International PEMS Conference

Conference Theme: Moving Towards Onboard Sensing, Analysis, and Reporting (OSAR)
Date: March 17th & 18th, 2022
Location: Marriott Riverside at the Convention Center, 3400 Market Street, Riverside, CA 92501

The 11th Annual International Portable Emissions Measurement System (PEMS) Conference is scheduled for March 17 & 18, 2022 in Riverside, California. This conference’s theme focused on a wide range of measurement systems, from fully compliant regulatory PEMS to mini-PEMS or smaller systems, which includes everything from micro PEMS (uPEMS), nano PEMS (nPEMS), in-situ sensors, Portable Activity Measurements Systems (PAMS), Real Emissions Assessment and Logging (REAL), and Simple Emissions Measurement Systems (SEMS).
