TL;DR: In this article, the authors present a set of challenging issues and specific recommendations for a scientific apportionment of particulate sources in different geographical regions of India, including methodological weakness, inappropriate sample size, implications of secondary aerosols and inadequate emission inventories.

TL;DR: Particulate source apportionment (SA) through receptor models is one of the existing tool to quantify contribution of particulate sources and source specific trends were considerably varied in terms of region and seasonality.

TL;DR: In this article, in-situ and space-borne observations reveal an extremely high loading of particulates over the Indo-Gangetic Plains (IGP), all year around, since the pollutants undergo long range transport from their source regions to the Indian mainland, leading to an outflow of continental pollutants into the Bay of Bengal (BoB), and a net advection of desert dust aerosols into the IGP from southwest Asia (SW-Asia), northwest India (NW-India) and northern Africa (N-Africa) during summers.

TL;DR: One-year ground monitoring data was compared to Moderate Resolution Imaging Spectroradiometer (MODIS) Level 3 retrieved aerosol optical depth (AOD) to identify trends in seasonal variation and compositional variation of particulates in Varanasi.

TL;DR: In this article, the ambient ammonia over Delhi along with other trace gases (NH3, NO, NO2, SO2 and CO) and particulates (PM2.5 and PM10) measured during December 2011 to June 2012 were characterized.
