The diurnal and spatial variation of concentration of aerosol particles in South India is studied and presented in this communication. Concentration of condensation particles was determined using condensation particle counter (CPC-3007) from different geographical stations, such as coastal, midland and highlands. For each geographical location, we collected data from the south, central and north Kerala regions to obtain the spatial features of the condensation particles. The diurnal patterns for highland in the slope are different from those of other stations. In the coastal, midland and flat terrain of highland stations, the variation in concentration of particles shows two distinct peaks, one in the morning and the other in the evening.
