Abstract: The atmospheric aerosol number concentration has been measured at Roorkee (29°52?N, 77°53?E, 275 m above mean sea level) in northern India during November 1998-August 1999 at a height of 9 m above ground level. The aerosol number concentration in summer season (April-July 1999) for morning, noon and evening periods has been analyzed, and the daily variation of aerosol number concentration has been related to selected meteorological parameters like: Relative humidity, temperature, rainfall and wind speed. The measurements were carried out with an optical particle counter. The counter monitors the number concentration of aerosols in the diameter size range from 0.3-5.0 ?m. The aerosol number concentration for upper size ranges (1.0-2.0 and 2.0-5.0 ?m) is maximum in June and minimum in July. The aerosol number concentration in small size ranges (0.3-0.5 and 0.5-1.0 ?m) decreases monotonically till the end of July. © 2003 Elsevier Ltd. All rights reserved.
