Atmospheric Black Carbon Loadings and Sources over Eastern Sub-Saharan Africa Are Governed by the Regional Savanna Fires

Vast black carbon (BC) emissions from sub-Saharan Africa are perceived to warm the regional climate, impact rainfall patterns, and impair human respiratory health. However, the magnitudes of these

Year‐Round Measurements of Dissolved Black Carbon in Coastal Southeast Asia Aerosols: Rethinking Its Atmospheric Deposition in the Ocean

Dissolved black carbon (DBC) is an important recalcitrant fraction of marine dissolved organic matter. Riverine discharge is the largest known source of oceanic DBC; however, the significance of

Regional monitoring of biomass burning using passive air sampling technique reveals the importance of MODIS unresolved fires.

Field-based sampling can provide more accurate evaluation than MODIS in regional biomass burning (BB) emissions given the limitations of MODIS on unresolved fires. Polyurethane foam-based passive air

Parameterizations of size distribution and refractive index of biomass burning organic aerosol with black carbon content

Abstract. Biomass burning organic aerosol (BBOA) impacts significantly on climate directly through scattering and absorbing solar radiation and indirectly through acting as cloud condensation nuclei.



Source apportionment of circum-Arctic atmospheric black carbon from isotopes and modeling

Year-round, isotope-constrained observations reveal strong seasonal variations in BC sources with a consistent and synchronous pattern at all Arctic sites, providing strong justification for targeted emission reductions to limit the impact of BC on climate warming in the Arctic and beyond.

Source forensics of black carbon aerosols from China.

This work uses "top-down" radiocarbon measurements of atmospheric BC from five sites including three city sites and two regional sites to determine that fossil fuel combustion produces 80 ± 6% of the BC emitted from China, establishing a much larger role for fossil fuelburning over East Asia.

Fossil and Nonfossil Sources of Organic and Elemental Carbon Aerosols in the Outflow from Northeast China.

F fossil and nonfossil contributions to elemental carbon (EC) and organic carbon (OC) of total suspended particles (TSP) from a regional receptor site in the outflow of Northeast China using radiocarbon measurement is unambiguously quantified.

Radiocarbon-based source apportionment of elemental carbon aerosols at two South Asian receptor observatories over a full annual cycle

Black carbon (BC) aerosols impact climate and air quality. Since BC from fossil versus biomass combustion have different optical properties and different abilities to penetrate the lungs, it is

Smoke radiocarbon measurements from Indonesian fires provide evidence for burning of millennia-aged peat

It is confirmed that peat emissions were the dominant source of aerosols in Singapore during the 2015 El Niño and provide a means for monitoring the success of policies designed to protect peatland areas during future drought events.

Brown Clouds over South Asia: Biomass or Fossil Fuel Combustion?

Using radiocarbon measurements of winter monsoon aerosols from western India and the Indian Ocean, it is determined that biomass combustion produced two-thirds of the bulk carbonaceous aerosols, as well as one-half and two- thirds of two black carbon subfractions, respectively.

Sources of carbonaceous aerosols and deposited black carbon in the Arctic in winter-spring: implications for radiative forcing

Abstract. We use a global chemical transport model (GEOS-Chem CTM) to interpret observations of black carbon (BC) and organic aerosol (OA) from the NASA ARCTAS aircraft campaign over the North

Convergence on climate warming by black carbon aerosols

Despite the established importance of BC to climate forcing, estimates of the DRF for BC, averaged over the globe, still span over a poorly constrained range from about 0.2–1 W⋅m−2 (7⇓–10).

Bounding the role of black carbon in the climate system: A scientific assessment

Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical properties. This assessment

Quantifying the occurrence and magnitude of the Southeast Asian fire climatology

Current emissions inventories of black carbon aerosol, an important component of PM2.5 and a powerful climate altering species, are highly uncertain in both space and time. One of the major and
