Air pollution impacts on human health are of serious concern in northern India, and over the Delhi National Capital Region (NCR) particular. The Kharif crop residue burning (CRB) is often blamed for degradation Delhi-NCR's seasonal air quality. However, concentration fine particulate matter (PM2.5) remained stable Delhi, while fire detection counts (FDCs) from satellites Punjab Haryana declined by 50% or more during 2015–2023. We measured PM2.5, carbon monoxide (CO) related parameters...
Abstract Considering the significant role of global methane emissions in Earth’s radiative budget, or regionally persistent increasing trends its emission are great concern. Understanding regional contributions various sectors to growth rate thus has policy relevance. We used a high-resolution inverse model independently optimize sectoral using GOSAT and ground-based observations for 2009–2020. Annual were calculated top-emitting countries, total anthropogenic trend studied. Global posterior...
Abstract In this study, we present a first-ever effort made to develop an ultra-high-resolution gridded emission inventory (i.e. ~ 0.4 km × km) for the Indian megacity Kolkata. As rising demand fossil fuels based energy along with spread of urban corridors have forced anthropogenic activities mounting level, therefore determining sources responsible is paramount importance. This has worsened not only regional air quality but also indirect effect on global quality. The spatial and temporal...
Abstract. The Indian capital megacity of Delhi is reeling under deteriorating air quality, and control measures are not yielding any significant changes, mainly due to a poor understanding sources emissions; hence, priority option in mitigation planning lacking. In this paper, we have made an attempt develop spatially resolved technological high-resolution gridded (∼0.4km×0.4km) emission inventory for eight major pollutants the region where activity data all possible unattended minor...
Particulate Matter (PM) pollution is a prime component of air and poses substantial risk to human health, including the eye. This work envisioned show impact PM2·5 on Ophthalmic disease prevalence in India. national-level observational-based cross-sectional retrospective study included hospital-reported ophthalmic outpatients 2019-20. The sector-wise high-resolution (0·1° × 0·1°) emission data along with annual average concentration for 2019 from NASA adopted factor analysis. Nearly 32·6...
Considering the need to identify sources of air pollution in smart city Bhubaneswar, a non-attainment India, high-resolution comprehensive gridded emission inventory (EI) eight primary pollutants has been developed for base year 2018. The involves detailed activity data with ~0.4 km × resolution covering using Geographical Information System (GIS) based statistical approach. In total, ~17 major and minor sectors are responsible city's crisis. Windblown road dust, transport sector,...
Abstract. Elevated emission of particulate matter (both PM2.5 and PM10) is not limited to urban areas. It’s the major pollutant that drives air quality across Indian sub-continent as well globe with adverse health impacts. Moreover, India home many polluted cities in recent years are among list most polluting globe. Therefore, identification sources their quantification along spatial variability has become paramount importance from modelling point view. The present work an attempt develop a...
Methane (CH4) is one of the most abundant organic trace gases in atmosphere having a strong global warming potential 28 100 years, significant GHGs, and has vital role atmospheric chemistry climate change. India home to largest number livestock world responsible for higher methane emissions from enteric fermentation manure management. In present study, Indian livestock, i.e., fermentation, estimated be 11.63 Tg yr-1 2019 using IPCC methodology recent census activity data Department Animal...
In recent years, air quality in Indian megacities has emerged as the most pressing global concern, with Asian being polluted. Unlike India's pollution capital, Delhi, Chennai is a megacity significantly impacted by industrial and transportation activities been designated non-attainment city Government of India under National Clean Air Programme. The first step towards sustained clean identifying sources causing megacity's to deteriorate. current study first-ever attempt develop bottom-up...

In this paper, we have made an attempt develop spatially resolved technological high-resolution gridded (~0.4 km × 0.4 km) emission inventory for eight major pollutants the region where activity data all possible unattended minor generated...
Volatile organic compounds including benzene, toluene, ethyl and xylene (BTEX) in the atmosphere have severe health environmental implications. These variables are trace elements atmosphere. There not enough measurement analysis studies related to atmospheric BTEX variation globally, even less developing countries like India. The present study analyses variations over an eastern Indian site, Bhubaneswar. continuous of is first its kind 2 years data (2017–2018), attempts find relation with...
