Trace gases emission from field burning of crop residues
Harvesting a crop generates a huge amount of crop residue. Uttar Pradesh tops the list of the Crop Residue Producing States followed by Punjab, Madhya Pradesh and so on. A large part of this crop residue is burnt in the open fields since the farmers do not have any worthwhile use of this waste. Burning of residues give rise to emissions of aerosols, major gases and trace gases. Aerosols are particulates composed of a variety of organic and inorganic species. They play an important role in atmospheric chemistry, boundary layer modification, radiation budget, human health and crop yield.
