Abstract:  Measurement of aerosol concentration has been carried out in view of some meteorological parameters like wind speed, temperature, relative humidity and rainfall during south-east (SE) monsoon (June-September 2006) and winter (November 2006-February 2007) at Roorkee, India. The measurements were done with the help of laser beam scatterometer for wide range of aerosols (0.05-3.0 μm). The present study reveals the fact that the number density of aerosols is very much affected by meteorological parameters. The aerosol concentration was minimum in August, September and November 2006 and remained around maximum during June-July 2006 and January-February 2007. During monsoon period, the rain plays important role in characterizing aerosol density. The aerosol concentration and size were found to be decreased during September 2006 although relative humidity was found to be very high due to scavenging of aerosol particles.
