The Measurement Assessment and Research Section (MARS) operates the Mobile Source Emissions Testing Facility in Sacramento, equipped with a heavy‑duty chassis dynamometer, advanced laboratory analyzers, Portable Emissions Measurement Systems (PEMS), and the Portable Emissions Acquisition System (PEAQS) to produce high‑quality, legally defensible emissions data. MARS’s mission is to support the development of heavy‑duty on‑road and off‑road vehicle regulations, strengthen emissions inventories, inform enforcement actions, advance the Clean Truck Check program, and drive research initiatives.

Through surveillance testing of in‑use on‑road and off‑road heavy‑duty vehicles and equipment, MARS provides critical insights into real‑world emissions performance and regulatory effectiveness. MARS also serves as a platform for evaluating and demonstrating new test approaches, advancing innovative methods for measuring in‑use emissions, and improving testing capabilities. Working collaboratively with CARB mobile source work groups, MARS develops and executes test plans, conducts comprehensive emissions testing, and delivers robust data analyses to guide policy decisions and protect air quality.

These efforts provide the scientific foundation to achieve reductions in criteria pollutants, greenhouse gases, and toxic air contaminants from the heavy‑duty sector.

MARS is seeking an Air Pollution Specialist to perform complex technical work related to in‑use emissions characterization of heavy‑duty (HD) on‑road and off‑road vehicles and equipment. The incumbent will conduct laboratory emissions testing using a heavy‑duty chassis dynamometer, perform on‑road emissions measurements with portable emissions measurement systems (PEMS), and ensure compliance with established test procedures, data quality objectives, and safety protocols.

Duties include developing and applying analytical methods for emissions data processing, validation, and interpretation; analyzing large datasets using computational tools; designing and executing test plans; operating advanced emissions…
