  • Carbonaceous Aerosol Measurement Instruments for Black Carbon Car Emission Factors

    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.

  • Cloud and Aerosol Instrument for Climate models & radiative forcing industry

    In 1996, the first Intergovernmental Panel on Climate Change (IPCC) issued a report that underscored how aerosols and clouds impact radiative fluxes and modulate climate. Their first report and all subsequent reports every seven years have emphasized how the level of scientific understanding (LOSU) remains low. This major gap in our understanding of how aerosols and clouds alter climate continues to drive the need for more widespread and accurate measurements, especially of black carbon (BC) aerosols that contribut...
