Measurements of Atmospheric Aerosol Concentration of Various Sizes During Monsoon Season at Roorkee, India

Measurement of aerosol concentration has been studied in view of some meteorological parameters such as wind speed, temperature, relative humidity and rainfall during southeast monsoon (June to September 2006) India. The measurements were done with the help of laser beam scatterometer for a wide range of aerosols (0.05-3.0 mu m). During monsoon period, the rain plays a very important role in characterizing the aerosol density. The aerosol concentration and size were found to be decreased during September 2006. The mode radius of aerosols was found to be decreased continuously during monsoon season. Wind does not play significant role in governing the mode radius.
