Short summary
This study provides quantitative information regarding the source contributions of the major non-methane volatile organic compound sources in Mohali in the northwestern Indo-Gangetic Plain. Combining in situ data and model analyses, we show that residential biofuel use and waste disposal emissions as well as the VOC burden associated with solvent use and industrial sources are overestimated by all emission inventories.
