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) andÅngström exponent (α) values exhibited larger day to day variation during crop residue burning period. The monthly meanÅngström exponent "α" and turbidity parameter "β" values during October 2007 were 1.31±0.31 and 0.36±0.21, respectively. The

AURA-OMI derived Aerosol Index (AI) and Nitrogen dioxide (NO 2 ) showed higher values over the study region during October 2007 compared to October 2006 suggesting enhanced atmospheric pollution associated with agriculture crop residue burning.
