TLDR
The atmospheric abundances of elemental carbon (EC), organic carbon (OC) and water-soluble organic carbon have been measured in aerosol samples collected during wintertime (December-March) from selected sites (urban, rural and high-altitude) in northern India as discussed by the authors.About:

A 1 year record of carbonaceous aerosols from an urban site in the Indo-Gangetic Plain: Characterization, sources, and temporal variability
TL;DR: In this paper, the authors present a comprehensive 1 year (January 2007-March 2008) data set on the chemical composition of ambient aerosols collected from an urban location (Kanpur) in the Indo-Gangetic Plain (IGP) and suggest that the varying strength of the regional emission sources, boundary layer dynamics, and formation of secondary aerosols all contribute significantly to the temporal variability in the mass concentrations of elemental carbon (EC), organic carbon (OC), and water-soluble OC (WSOC).

Day–night variability of EC, OC, WSOC and inorganic ions in urban environment of Indo-Gangetic Plain: Implications to secondary aerosol formation
Kirpa Ram,Manmohan Sarin +1 more
TL;DR: In this paper, the authors report on the day and night-time variability of EC, OC, WSOC and inorganic ions in ambient aerosols (PM 2.5 and PM 10 ) sampled from an urban site (Kanpur) in the Indo-Gangetic Plain.

Temporal trends in atmospheric PM₂.₅, PM₁₀, elemental carbon, organic carbon, water-soluble organic carbon, and optical properties: impact of biomass burning emissions in the Indo-Gangetic Plain.
TL;DR: The highest b(scat) was associated with the dust storm event (April 17, 2009) over northern Iraq, eastern Syria, and southern Turkey; thus, resulting in high SSA during March-April compared to 0.93 ± 0.02 in October-February.

Long-term record of aerosol optical properties and chemical composition from a high-altitude site (Manora Peak) in Central Himalaya
TL;DR: In this article, a long-term study, conducted from February 2005 to July 2008, involving chemical composition and optical properties of ambient aerosols from a high-altitude site (Manora Peak: 29.4° N, 79.5° E, ~1950 m a.s.l.) in the central Himalaya is reported.

Seasonal characteristics of aerosols (PM2.5 and PM10) and their source apportionment using PMF: A four year study over Delhi, India
TL;DR: Conditional Bivariate Probability Function plots revealed that the maximum concentrations of PM2.5 and PM10 were carried by north westerly winds (north-western Indo Gangetic Plains of India) and the seasonal differences in VE contributions were not very striking.

Estimates of the direct and indirect radiative forcing due to tropospheric aerosols: A review
Jim Haywood,Olivier Boucher +1 more
TL;DR: A review of the many developments in estimates of the direct and indirect global annual mean radiative forcing due to present-day concentra- tions of anthropogenic tropospheric aerosols since the Inter- governmental Panel on Climate Change (1996) is presented in this paper.

Climate Effects of Black Carbon Aerosols in China and India
TL;DR: A global climate model used to investigate possible aerosol contributions to trends in China and India found precipitation and temperature changes in the model that were comparable to those observed if the aerosols included a large proportion of absorbing black carbon (“soot”), similar to observed amounts.
