Biomass burning emissions on regional-global scales
Biomass burning (BB) is the second largest source of trace gases and the largest source of primary fine carbonaceous particles in the global troposphere. Many recent BB studies have provided new emission factor (EF) measurements for non-methane organic compounds (NMOC), which are highly reactive …

Multiphase Aging of Atmospheric Biomass Burning Brown Carbon
… of carbonaceous aerosol, primarily emitted from biomass burning sources such as wildfires. These aerosol particles have significant implications on climate through their ability to absorb light, and potentially contributing to warming effects. Due to the expected increase of wildfire activity in …

Effects of biomass-burning aerosol loading on Southern African climate
… study highlights the importance of including all biomass burning emissions, from the aerosols directly released from fires to the precursor gases, as different radiative forcings will be obtained from different chemical species, and, therefore, different circulation patterns are likely to be …

Supermicron-size aerosol particles originating from biomass burning in south-central Africa
… aerosol particles (SAPs) within a biomass burning (BB) plume during research flights over the South East Atlantic Ocean outside of clouds at times when no liquid water was detected by the King liquid water probe. Numerous SAPs sized between 10 µm and 1.52 mm were observed at …

Field measurements and atmospheric simulation chamber studies of selected biomass burning marker compounds
Biomass burning is a key contributor to ambient air pollution, which has significant impacts on climate and health. Biomass burning emits both solid particles and gaseous species known as volatile organic compounds (VOCs) which can undergo chemical oxidation reactions in the atmosphere with …

Impacts of long-range transport of biomass burning on air quality in Texas.
… physical and chemical properties of transported biomass burning (BB) smoke and their impact on background air quality in Port Aransas, an industrialized coastal site in Texas. To achieve these objectives, mobile and stationary field experiments were conducted to measure the impact of local …

A comparison and synthesis of polar-orbiting and geostationary observations of African biomass burning
… timing, location and characteristics of African biomass burning is primarily derived from two satellite sensors: the geostationary Spinning Enhanced Visible and Infrared Imager (SEVIRI) and the polar-orbiting Moderate Resolution Imaging Spectroradiometer (MODIS). Due to opposing limitations in …

Formation of ozone and growth of aerosols in young smoke plumes from biomass burning
The combustion of biomass is a major source of atmospheric trace gases and aerosols. Regional and global-scale models of atmospheric chemistry and climate take estimates for these emissions and arbitrarily "mix" them into grid boxes with horizontal scales of 10-200 km. This procedure ignores the …

Up in smoke: biomass burning and atmospheric emissions in the Sudanian savanna of Côte d’Ivoire
… influences on climate change with an emphasis on biomass burning at the local and regional scales in the sudanian savanna of Côte d’Ivoire. Fire is an important management tool in farming and pastoral systems of West Africa. The climate change literature argues that biomass burning is an important …

Measurements of Reactive Trace Gases and Variable Ozone Formation Rates in South Carolina Biomass Burning Plumes
<p>Biomass burning (BB) is the second largest source of trace gases and the largest source of primary fine carbonaceous particles in the global troposphere. BB trace gases and particles are of both regional and global importance. In the US, prescribed fire and wildfire are the two major fire types …

AN APPROACH TO ESTIMATE GLOBAL BIOMASS BURNING EMISSIONS OF ORGANIC AND BLACK CARBON FROM MODIS FIRE RADIATIVE POWER
Biomass burning is an important global phenomenon affecting atmospheric composition with significant implications for climatic forcing. Wildland fire is the main global source of fine primary carbonaceous aerosols in the form of organic carbon (OC) and black carbon (BC), but uncertainty in aerosol …

Observations of aerosol-cloud interactions with varying vertical separation between biomass-burning aerosols and stratocumulus clouds over the South-East Atlantic
… Atlantic varied depending on whether overlying biomass-burning aerosols were present immediately above, or separated from cloud tops. Forty vertical cloud profiles were classified into two regimes, Mixing and Separated, according to whether the plume of densest aerosols was mixing into or …

A 2007 aircraft-based study of plumes from biomass burning origin from Mexico and Central America advected over south Texas and the western Gulf of Mexico.
Biomass burning is the burning of living and dead vegetation which includes grasslands, forests, and agricultural lands (Levin, 1998). It is a global phenomenon and serves a multitude of purposes such as clearing of forests and brushland for agricultural use; control of weeds; production of …
