Research Highlight


Air quality in megacity Delhi affected by countryside biomass burning

During the high loadings of PM2.5 and BC in the winter, BC in Delhi come to a greater extent from biomass burning, on average 40%. These elevated winter-time biomass contributions coincide with regional-scale crop residue burning, in addition to other countryside biomass burning. Hence, the paradigm that megacities are strongly affecting their surrounding regions are here complemented, or seasonally even reversed, as countryside combustion practices are here seen to strongly deteriorate the air quality and contribute to wintertime haze in megacity Delhi.
