Short summary
This study refines India’s methane inventory, addressing data gaps and improving climate research. It identifies 25 sources, including agriculture, wetlands, and fossil fuels, enhancing India’s global data representation. Emissions peak in the Indo-Gangetic Plain and coastal states, highlighting mitigation priorities. Urban emissions are lower, suggesting underestimation. This dataset helps policymakers design targeted reduction strategies, supporting India’s climate goals and global efforts.

Short summary
Elevated emission of particulate matter is not limited to urban areas, led to poor air quality across the country. Emission Inventory is the first line of defensive tools for air quality management and understanding and identification of the source of pollutants. The present work is an attempt to develop a high-resolution (~10 km) national inventory of particulate pollutants in India for 2020 using IPCC methodology. The developed dataset is vital piece of information for mitigation strategies.

Short summary
Our paper uses novel satellite datasets and high-resolution emissions datasets alongside a back-trajectory model to investigate the balance of local and external sources influencing NOx air pollution changes in Delhi. We find in the post-monsoon season that NOx from local and non-local transport emissions contributes most to poor air quality in Delhi. Therefore, air quality mitigation strategies in Delhi and surrounding regions are used to control this issue.

Short summary
The developed emission inventory identifies all the potential anthropogenic sources active in the Delhi NCR. The decadal change (2010–2020) and the changing policies have also been illustrated to observe the modulation in the sectorial emission trend. Emission hotspots with possible source-specific mitigation strategies have also been highlighted to improve the air quality of the Delhi NCR. The provided dataset is a vital tool for air quality and chemical transport modeling studies.
The developed emission inventory identifies all the potential anthropogenic sources active in...
