This research article investigates the diurnal and seasonal characteristics of aerosol optical properties such as absorbing and scattering coefficients and single scattering albedo (SSA) over the semi-arid region of Solapur (17 degrees 43 ' 45.4332 '' N, 75 degrees.51 ' 24.4476 '' E, 457 m AMSL), India. These aerosol optical properties play a crucial role in understanding the aerosol radiative forcing and thereby the climate impact of atmospheric aerosols. However, there is a lack of comprehensive studies focusing on the temporal dynamics of aerosol optical properties in peninsular India especially from the arid region. To address this gap, we conducted multiyear (July 2019 to October 2022) measurement campaign to characterize the aerosol optical properties at Solapur. Our findings reveal significant temporal variations in the aerosol optical properties on the diurnal, seasonal, and annual scales. Diurnally, the aerosol optical properties showed distinct patterns, with higher absorption and scattering coefficients during daytime due to increased anthropogenic activities and local emissions. Seasonally, the aerosol loading was influenced by changes in the prevailing meteorological conditions, including aerosol scavenging due to the monsoonal influences and regional transport of aerosols. The intra-annual variability suggested the possible influence of various factors such as changes in local emissions, land use patterns, and local boundary layer conditions. Furthermore, the SSA values showed slight annual variation, with maximum values in post monsoon and minimum during monsoon period. SSA value (mean 0.71 +/- 0.02 and median 0.73 +/- 0.03) indicated towards significant role of absorbing aerosols in aerosol radiative forcing and thereby atmospheric warming over this semi-arid location.
