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, […]

FOREST FIRE BLACK CARBON POLLUTION

Motivation Savanna fires are the largest global source of biomass burning emissions. While these compounds adversely impact the local air quality and long-term climate change, documentation on qualitative and quantitative characteristics of the emissions is still very scarce. The adverse effects of smoke on air quality and visibility are of great concern for fire and […]

GLOBAL BLACK CARBON POLLUTION

Black carbon (BC) has a unique and important role in the Earth’s climate system because it absorbs solar radiation, influences cloud processes, and alters snow and ice cover melting. BC is the second-largest climate warmer, after carbon dioxide. A large fraction of atmospheric black carbon concentrations is due to anthropogenic activities. Concentrations respond quickly to […]

URBAN MAPS OF BLACK CARBON POLLUTION

Motivation Urban air includes many microenvironments to which the citizen is exposed at different times of the day. The air quality of most of them is very different from that measured at urban background monitoring sites. Access to detailed comparisons in air quality variations encountered when commuting through a city offers the urban traveler a […]

MINE VENTILATION OPTIMIZATION

Motivation Mines use large ventilation systems to maintain a safe and healthy environment for miners. Dilution of diesel particulate matter (DPM) is often a key factor in determining the required quantities of ventilation air. DPM emissions and exposure levels are highly variable depending on mine schedules and activities. Due to lacking the technology to monitor […]
