Black carbon (BC) is produced by incomplete combustion of biomass by wildfires and
burning of fossil fuels. BC is environmentally persistent over centuries to millennia …

Evidence is accumulating that sorption of organic chemicals to soils and sediments can be
described by “dual-mode sorption”: absorption in amorphous organic matter (AOM) and …

After vegetation fires considerable amounts of severely or partly charred necromass
(referred to here as char) are incorporated into the soil, with long-term consequences for soil …

Abstract The 1999 Regional Haze Rule provides a context for this review of visibility, the
science that describes it, and the use of that science in regulatory guidance. The scientific …

In the past 30 years, the field of black carbon (BC) research has expanded broadly,
stretching from its traditional core in the atmospheric sciences into oceanography, soil …

Routine soil surveys for estimating the soil organic carbon (SOC) pool account for a soil
depth of about 1 m. Deeper soil horizons, however, may have a high capacity to sequester …

Carbonaceous aerosols cause strong atmospheric heating and large surface cooling that is
as important to South Asian climate forcing as greenhouse gases, yet the aerosol sources …

The carbon (C) cycle in boreal regions is strongly influenced by fire, which converts biomass
and detrital C mainly to gaseous forms (CO 2 and smaller proportions of CO and CH 4), and …

Biomass burning and resulting fire regimes are major drivers of vegetation changes and of
ecosystem dynamics. Understanding past fire dynamics and their relationship to these …

Charring of organic carbon (OC) during thermal/optical analysis is monitored by the change
in a laser signal either reflected from or transmitted through a filter punch. Elemental carbon …
