Detecting the influence of fossil fuel and bio-fuel black carbon aerosols on near surface temperature changes
fossil fuel bio-fuel black carbon aerosols surface temperature
2011/2/24
Past research has shown that the dominant influence on recent global climate changes is from anthropogenic greenhouse gas increases with implications for future increases in global temperatures. One m...
Using measurements for evaluation of black carbon modeling

2010/8/16
The refractory black carbon (rBC) mass, size distribution (190–720 nm) and mixing state in sub-micron aerosols were characterized from late February to March 2007 using a single particle incandescence...
Black carbon aerosols and the third polar ice cap
Black carbon aerosols the third polar ice cap
2010/8/13
Recent thinning of glaciers over the Himalayas (sometimes referred to as the third polar region) have raised concern on future water supplies since these glaciers supply water to large river systems t...
Continental scale Antarctic deposition of sulphur and black carbon from anthropogenic and volcanic sources

While Antarctica is often described as a pristine environment, there is an increasing awareness of the potential threats from local pollution sources including tourist ships and emissions associated w...
Black carbon ageing in the Canadian Centre for Climate modelling and analysis atmospheric general circulation model
Black carbon Canadian Centre atmospheric general circulation model
2009/2/12
Black carbon (BC) particles in the atmosphere have important impacts on climate. The amount of BC in the atmosphere must be carefully quantified to allow evaluation of the climate effects of this type...
Black carbon or brown carbon? The nature of light-absorbing carbonaceous aerosols
Black carbon brown carbon light-absorbing carbonaceous aerosols
2009/1/13
Although the definition and measurement techniques for atmospheric "black carbon" ("BC") or "elemental carbon'' ("EC") have long been subjects of scientific controversy, the recent discovery of light...
