Atmospheric scientists fires resolve ice question climate models
2020/9/4
When fossil fuel or biomass burns, soot -- also known as black carbon -- fills the air. Black carbon is an important short-term climate driver because it absorbs solar energy and can affect the format...

While efforts to limit ozone precursor emissions tend to focus on industrial activities and fossil fuel combustion in the United States and China, a new University of Maryland-led study suggests that ...
Global fire emissions and the contribution of deforestation, savanna, forest, agricultural, and peat fires (1997–2009)
Global fire deforestation savanna forest agricultural peat fires
2010/12/28
New burned area datasets and top-down constraints from atmospheric concentration measurements of pyrogenic gases have decreased the large uncertainty in fire emissions estimates. However, significant ...
Nitrogen oxides and PAN in plumes from boreal fires during ARCTAS-B and their impact on ozone: an integrated analysis of aircraft and satellite observations
Nitrogen oxides and PAN boreal fires ARCTAS-B aircraft and satellite observations
2010/10/21
We determine enhancement ratios for NOx, PAN, and other NOy species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examine the impact of these emissions on t...

2010/2/21
We analyze an extensive record of aerosol smoke plume heights derived from observations over North America for the fire seasons of 2002 and 2004–2007 made by the Multi-angle Imaging SpectroRadiometer ...
Biomass burning aerosol emissions from vegetation fires: particle number and mass emission factors and size distributions
Biomass burning aerosol vegetation fires mass emission factors
2010/2/21
Aerosol emissions from vegetation fires have a large impact on air quality and climate. In this study, we use published experimental data and different fitting procedures to derive dynamic particle nu...
