Sentences with phrase «as black carbon absorb»

Furthermore, it is suggested that aerosols with high absorptivity such as black carbon absorb solar radiation in the lower atmosphere, cool the surface, stabilise the atmosphere and reduce precipitation (Ramanathan et al., 2001).

Not exact matches

Black carbon aerosols — particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way — are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting.

In the past, numerous studies have identified black carbon aerosols emitted from combustion of fossil fuels and residential biofuels as the dominant light - absorbing aerosol over South Asia.

«It's important to note that the article doesn't address the direct and immediate impact of forest burning, such as emissions of black carbon [considered a major driver of global warming owing to its high capacity for absorbing solar radiation].

Soot particles, also known as black carbon aerosols, affect climate by absorbing sunlight, which warms the surrounding air and limits the amount of solar radiation that reaches the ground.

Two properties dominate reflectivity in dry snow — the size of snow grains, which become larger and more absorbent as they melt, and the presence of dark impurities that absorb the sun's energy, predominantly black carbon and mineral dust, which also cause the snow to melt faster.

Instead, black carbon is expelled into the atmosphere combined with other compounds such as sulfates, which affect their heat - absorbing and reflective properties.

Other particles such as soot (black carbon) absorb the sunlight and drive temperature rise, leading to local warming of the atmosphere level where the soot particles circulate.

Some aerosols, such as black carbon, absorb sunlight and produce a warming effect that might also inhibit rainfall.

More on the important role that black carbon soot plays in increasing global warming and what can be done about it: A new study published in Nature Geoscience found that the amount of solar radiation absorbed increased as the ratio of black carbon to sulphate rose.

At a recent House hearing, five top scientists stated that black carbon could account for close to 16 % of the planet's gross warming and that it may be second only to carbon dioxide in its potency as a GHG — ahead of methane.The black carbon absorbs incoming sunlight, converting it into infrared radiation and emitting it to the atmosphere — a process we outlined in an earlier post describing the impact of «dirty snow» on global warming.

Even more striking was evidence that the CO2 level in the atmosphere had dipped during those centuries — perhaps because so much farmland had reverted to carbon - absorbing forest as a result of plagues, including the Black Death in Eurasia and smallpox in the Americas.

Theoretically, coatings of essentially non-absorbing components such as organic carbon or sulphate on strongly absorbing core components such as black carbon can increase the absorption of the composite aerosol (e.g., Fuller et al., 1999; Jacobson, 2001a; Stier et al., 2006a), with results backed up by laboratory studies (e.g., Schnaiter et al., 2003).
