BLACK CARBON CAR EMISSION FACTORS

Motivation

One of the main sources of air pollution is traffic. To estimate the traffic contribution to air pollution the emissions are calculated from the vehicle fleet composition and vehicle emission factors (EF). Since the emission factors depend on vehicle type (cars, heavy and light duty), engine maintenance, driving environment (city, highway, regional roads) and weather, the emmision factors must be measured for in-use vehicles in actual traffic situations.

Two methods can be used to determine the so-called “real world” emission factors. The first method is the stationary method where EFs are calculated from the instantaneous rise of pollutants as a vehicle passes the measuring station. The second is the chasing method where vehicle emissions are measured by driving a mobile station behind the measured vehicle on the road.

APPLICATIONS

Aerosol Magee Scientific instruments are deep underground to monitor diesel exhaust in mines and at the Base Camp of Mt. Everest to measure the regional pollution of remote locations. Our instruments are used at research stations from the Amazon Jungle to the Sahara Desert; from Spitzbergen to the South Pole. Our instruments are installed in agency stations from San Francisco to Shanghai, from Dublin to Delhi, and everywhere in between. They are used for fundamental research, air quality monitoring, environmental engineering, and other applications.
