In Situ Characterization of Optical Absorption by Carbonaceous Aerosols: Calibration and Measurement
Light absorption by aerosols has a great impact on climate change. A Photoacoustic spectrometer (PA) coupled with aerosol-based classification techniques represents an in situ method that can quantify the light absorption by aerosols in a real time, yet significant differences have been reported …

Characterization of carbonaceous aerosols from biofuel combustion: emissions and climate relevant properties
… on climate is significant but highly uncertain. Carbonaceous aerosols, composed of black carbon (BC) and organic carbon (OC), are important to understand aerosol radiative forcing due to their prevalence in the atmosphere. Biofuel combustion is responsible for nearly 20% of primary BC and OC …

Chemistry of carbonaceous aerosols : studies of atmospheric processing and OH-initiated oxidation
Carbonaceous aerosols are among the most prevalent yet least understood constituents of the atmosphere, particularly in urban environments. We have performed analyses of field samples and laboratory studies to probe the physico-chemical properties of soot and organic aerosols in a complimentary …

Exploring the absorption properties and direct radiative impact of atmospheric carbonaceous aerosols
Atmospheric aerosols are important due to their adverse effects on human health and their direct and indirect radiative effects on climate, which are significant and very uncertain factors contributing to global climate change. In estimating the direct radiative effect (DRE), the absorption from …

Development of improved sampling and analysis methods for measuring organic, elemental, and water-soluble organic carbon in atmospheric aerosols and application to aerosol studies in Europe and tropical/equatorial and oceanic regions
… (2) to deploy improved collection procedures for carbonaceous aerosols, whereby the sampling artifacts are better controlled or can be corrected for; (3) to perform detailed carbonaceous aerosol characterisation studies in Belgium and at urban and forested sites throughout Europe and (4) in the …

AN APPROACH TO ESTIMATE GLOBAL BIOMASS BURNING EMISSIONS OF ORGANIC AND BLACK CARBON FROM MODIS FIRE RADIATIVE POWER
… 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 emission estimates from biomass burning is still rather large. Application of satellite based measures of fire radiative power (FRP) has been …

Spatial trends in surface-based carbonaceous aerosol measurements during DISCOVER-AQ in Houston, TX.
Carbonaceous aerosol (both fine particulate matter (PM₂.₅) and total suspended particulate (TSP)) were collected during NASA's DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) in Houston, TX during September 2013. Four …
