Sharma, AR, Kharol, SK, Badarinath, KVS, Singh, D (2010). "Impact of agriculture crop residue burning on atmospheric aerosol loading - a study over Punjab State, India". ANNALES GEOPHYSICAE, 28(2), 367-379.

The present study deals with the impact of agriculture crop residue burning on aerosol properties during October 2006 and 2007 over Punjab State, India using ground based measurements and multi-satellite data. Spectral aerosol optical depth (AOD) and Angstrom exponent (alpha) values exhibited larger day to day variation during crop residue burning period. The monthly mean Angstrom exponent 'alpha' and turbidity parameter 'beta' values during October 2007 were 1.31 +/- 0.31 and 0.36 +/- 0.21, respectively. The higher values of 'alpha' and 'beta' suggest turbid atmospheric conditions with increase in fine mode aerosols over the region during crop residue burning period. AURA-OMI derived Aerosol Index (AI) and Nitrogen dioxide (NO2) showed higher values over the study region during October 2007 compared to October 2006 suggesting enhanced atmospheric pollution associated with agriculture crop residue burning.
