ADVANCED APPORTIONMENT OF CARBONACEOUS AEROSOLS

Motivation The advanced TC/BC(l) method can be used to study the influence of anthropogenic processes, such as fossil fuel combustion (traffic) or biomass burning (wildfires), on air quality and thus to study the impact of those processes on our daily life, e.g., climate change and public health.  

MOBILE MEASUREMENT OF BLACK CARBON

Motivation Mobile measurement of aerosol Black Carbon (BC) and Brown Carbon (BrC) allows for the mapping of air pollution sources and exposures at fine spatial scales on-road measurement of emissions and exposures or rapid deployment either between pre-defined fixed sites or to emergency situations. These capabilities complement traditional monitoring approaches for air pollution assessments.   […]

OFF GRID BLACK CARBON MONITORING

Motivation Carbonaceous aerosols are particulate matter ( produced by the incomplete combustion of fuels. Black Carbon (BC) is typically produced by high temperature combustion such as engine exhaust and industrial processes. Brown Carbon (BrC) is typically produced by lower temperature biomass combustion such as domestic cooking and heating stoves, forest fires, agricultural waste burning etc. […]

REAL TIME WILDFIRE SMOKE MONITORING

Motivation As the world’s climate becomes hotter and drier, wildfires are increasing in size, duration and severity.  Wildfire smoke can be transported for hundreds or thousands of kilometers in high concentrations.  It contains both “black” carbonaceous material (‘BC’) from high-temperature combustion; and “brown” material (‘BrC’) from smoldering, which contains an enormous range of organic compounds […]

STUDIES OF AEROSOL CARBONACEOUS MATTER

Motivation This Application Note describes the combination of the Carbonaceous Aerosol Speciation System (CASS) and an Aerosol Chemical Speciation Monitor (ACSM). The ACSM is used for real-time monitoring of non-refractory aerosol particle mass and chemical composition.  It reports particulate ammonium, nitrate, sulfate, chloride, and other organic species as “organic matter” (OM).  The ACSM is one component of […]

FOSSIL FUEL VS. BIOMASS BURNING BLACK CARBON

Motivation Atmospheric pollution represents a risk factor for respiratory and cardiovascular diseases and cancer. The two major contributions come from traffic emissions and biomass burning. On-road and off-road diesel engines account for ~70% of BC emissions in Europe, North America, and Latin America. In contrast, the burning of residential solid fuels, especially coal and biomass, […]

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 […]

VERTICAL PROFILE OF BLACK CARBON POLLUTION

Motivation BC profiles are globally scarce compared to ground-level data. Thus, there is a clear need to improve the knowledge about aerosol vertical profiles. This is true, especially over mountainous regions. Detailed vertical profiles of aerosol parameters are needed to quantify the effects of aerosols on radiative forcing and clouds and how these, in turn, […]

MARINE VESSEL BLACK CARBON POLLUTION

Motivation The duration of use is usually significantly longer for marine vessels than for roadside vehicles. Therefore, these vessels are often powered by relatively old engines, which may propagate air pollution. Also, the quality of fuel used for marine vessels is usually not comparable to the quality of fuels used in the automotive sector. Therefore, […]
