Anthropogenic impact on the temporal variations of black carbon and surface aerosol mass concentrations at a tropical semi-arid station in southeastern region of India

Temporal Variability of Equivalent Black Carbon Components in Atmospheric Air in Southern Poland

“…Atmospheric aerosols are receiving increasing attention in scientific research primarily due to their importance in influencing climate, restricting visibility, and causing harmful effects on human health and ecosystem stability [1][2][3]. One of the most important components of atmospheric aerosols is a carbonaceous component which can be in the range of about 20-45% of PM 2 .…”

“…This component affects cloud albedo by changing the hygroscopicity of cloud condensation nuclei, which in turn can lead to changes in cloudiness and precipitation rates [20][21][22]. Being chemically inert and concentrated in submicron-sized particles, BC has a long atmospheric lifetime (of several days to weeks) and hence-with favorable atmospheric conditions such as no precipitation-can be subject to long-range transport processes [1,17,23,24]. Transported BC particles can accumulate on a surface covered with snow or ice, and therefore can contribute to accelerating the melting of glaciers by increasing the temperature of their surface [25].…”

Black carbon aerosol variations over Patiala city, Punjab, India—A study during agriculture crop residue burning period using ground measurements and satellite data

“…Tripathi et al (2007) observed enhanced BC concentrations at $ 1200 m, causing increase in the lower atmospheric heating rate. Due to significant impacts of BC aerosols on local, regional and global scales numerous studies have been conducted over India focusing on BC variations, their association with atmospheric dynamics, sources and sinks as well as climate implications (Babu et al 2002;Ganguly et al, 2006;Badarinath et al, 2007a;Ramachandran and Rajesh, 2007;Pathak et al, 2010;Balakrishnaiah et al, 2011;Das and Jayaraman, 2011; among many others).…”

Direct radiative forcing properties of atmospheric aerosols over semi-arid region, Anantapur in India

“…The appearance of higher frequency in the case of larger AOD values during summer may be due to the swelling of aerosol mixing with the uptake of water vapor and agricultural dust over the area. Balakrishnaiah et al (2011) reported that the high frequency was observed for AOD N 0.6 during the summer. Fig.…”
