TL;DR: Aerosol black carbon (BC) mass concentrations measured continuously during a multi-platform field experiment, Integrated Campaign for Aerosols gases and Radiation Budget (ICARB, March-May 2006), from a network of eight observatories spread over geographically distinct environments of India, (which included five mainland stations, one highland station, and two island stations (one each ill Arabian Sea and Bay of Bengal)) are examined for their spatio-temporal characteristics as mentioned in this paper.
Journal ArticleDOI
Tethered balloon-born and ground-based measurements of black carbon and particulate profiles within the lower troposphere during the foggy period in Delhi, India

TL;DR: The ground and vertical profiles of particulate matter (PM) were mapped as part of a pilot study using a Tethered balloon within the lower troposphere (1000m) during the foggy episodes in the winter season of 2015-16 in New Delhi, India to suggest the need for immediate, stringent measures to improve the regional air quality in the northern India.
Journal ArticleDOI
Source characterization for aerosol constituents and changing roles of calcium and ammonium aerosols in the neutralization of aerosol acidity at a semi-urban site in SW India
TL;DR: In this paper, anthropogenically derived particles (Non seasalt and non crustal fractions of SO4, Cl, K, Ca and Mg together with NO3, NH4, Cu, Zn and black carbon) contributed about 73% of the total measured TSP.
Journal ArticleDOI

TL;DR: In this article, physical, chemical and optical properties of aerosols over a tropical semi-arid location, Agra in north India, were undertaken during December 2004, and the average concentration of total suspended particulates (TSP) increased by about 1.4 times during intense foggy/hazy days.
Journal ArticleDOI
Influence of local sources on rainwater chemistry over Pune region, India
TL;DR: In this article, chemical analyses of rainwater samples were collected at five locations in the Pune region, an urban area in the south-west part of India, during 2006-2009.
