Exploring radiative forcing sensitivity to aerosol optical properties across varied geographical regions in India

In this study, we center our attention on the investigation of key aerosol optical properties, specifically the asymmetry parameter (ASY), aerosol optical depth (AOD), an d single scattering albedo (SSA). Our research delves into the spatio-temporal distribution patterns of these aerosol optical properties across four distinct locations within India, namely Gandhi College, Kanpur, Jaipur, and Pune. These selected sites encompass the major classifications of aerosols, encompassing both anthropogenic and natural sources. Within the purview of these available aerosol optical properties, we endeavor to quantify the direct aerosol radiative forcing (DARF). To further enhance the rigor of our findings, we employ the control variable method to assess the uncertainty a ssociated with direct aerosol radiative forcing concerning aerosol optical properties. Our results underscore that the asymmetry parameter (ASY) exerts a relatively minor influence on DARF, while single scattering albedo (SSA) and aerosol optical depth (AOD) wield substantial impact. Furthermore, th is influence is contingent upon the specific aerosol type and exhibits notable regional variations, as different parameters manifest diverse effects contingent upon their respective geographical contexts.
