Abstract

The bistatic, continuous wave Argon ion lidar system developed at the Indian Institute of Tropical Meteorology, Pune, India has been used to examine the nature of variation of laser-return signal strength (from a constant altitude in the lower atmosphere) with scattering angle (varied from 90 to 175°). The observed variation correlates well with the calculated variation in Mie scattering cross section assuming a power law type particle size distribution. The values of size index and real part of refractive index at the observation site are found to be around 4.6 and 1.53, respectively. Results suggest the presence of water-soluble, dust-like aerosols with predominance of larger sized particles during the premonsoon (March–May) and SW monsoon (June–September) seasons in the lower atmosphere at the lidar site.
