TL;DR: In this article, the authors quantify the impact of black carbon aerosols on snow cover and precipitation from 1990 to 2010 over the Indian subcontinental region using two different BC emission inventories.

TL;DR: In this article, a high resolution emission inventory of PM 10 and PM 2.5 has been developed for the metropolitan city of Delhi for the year 2010, which involves detailed activity data and developed for a domain of 70.km-×-65.km with a 1.67-km resolution covering Delhi and surrounding region using Geographical Information System (GIS) technique.

TL;DR: This work quantifies the share of biomass burning in deteriorating Delhi's air quality during 2018 using the SAFAR chemical transport model that has been validated with dense observational network of Delhi and develops the realistic high-resolution emission inventory of the hazardous pollutants PM2.5 due to stubble burning.

TL;DR: The temporal analysis revealed a progressive decrease in NO2 for all seven cities during the 2020 lockdown period and the NO2 temporal patterns matched the AOD signal; however, the correlations were poor.

TL;DR: In this article, a Geographical Information System (GIS) based methodology has been used to construct the black carbon (BC) emission inventory for the Indian geographical region, and the distribution of emissions from a broader level to a spatial resolution of 1{sup o} x 1{Sup o} grid has been carried out by considering micro level details and activity data of fossil fuels and bio-fuels.
