“…), centre of the agrarian region of northwest India, close to Shivalik Hills in the east and Thar Desert in the southwest. The Punjab State suffers from severe fog, haze and smog during winter period due to anthropogenic activities and low temperatures (Mittal et al, 2009). The climate of the city is very hot in the summer and very cold in the winter.…”

Abstract. 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 higher values of "α" and "β" 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 (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.

“…The area around Patiala city, Punjab State, India is predominantly rural, with farmers cultivating wheat, rice and other crops. Crop stubble burning in open fields in and around the city is a major pollution source during October-November each year (Mittal et al, 2009). …”

“…Farmers opt for burning because it is a quick and easy way to manage the large quantities of crop residues and prepare the field for the next crop well in time. Agricultural residues burning may emit significant quantity of air pollutants like CO 2 , N 2 O, CH 4 , emission of air pollutants such as CO, NH 3 , NO x , SO 2 , NMHC, volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) and particulate matter like elemental carbon at a rate far different from that observed in savanna/forest fire due to different chemical composition of the crop residues and burning conditions (Zhang et al, 2011, Mittal et al, 2009. Several researchers have estimated the emission of different species from crop residue burning using IPCC factors, but they have covered only few gaseous pollutants (N 2 O, CH 4 , NO x , and SO 2 ) (Venkataraman et al, 2006;Sahai et al, 2007); or from a specific area and crop (Badrinath et al, 2006;Sahai et al, 2007).…”

Agricultural crop residue burning contribute towards the emission of greenhouse gases (CO 2 , N 2 O, CH 4 ), air pollutants (CO, NH 3 , NO x , SO 2 , NMHC, volatile organic compounds), particulates matter and smoke thereby posing threat to human health. In the present study a state-wise inventory of crop residue burnt in India and the air pollutants emitted was prepared using the Inter-Governmental Panel on Climate Change (IPCC) national inventory preparation guidelines for the year 2008-09. Total amount of residue generated in 2008-09 was 620 Mt out of which ~15.9% residue was burnt on farm. Rice straw contributed 40% of the total residue burnt followed by wheat straw (22%) and sugarcane trash (20%). Burning of crop residues emitted 8.

“…For example, crop residues are burnt worldwide including the USA, India, China (e.g. McCarty et al, 2009), and this has been found to significantly increase aerosol and greenhouse gases (GHGs) in ambient air (Mittal et al, 2009;Yang et al, 2008). In other cases like eastern Corn Belt in USA, where soils are often wet after harvest, possibility of soil compaction caused by cattle grazing of residues remained in the field is one of the concerns from the viewpoint of soil conservation (Sulc and Tracy, 2007).…”
