Abstract
Single Scattering Albedo (SSA) is one of the most important parameters in deciding the type of aerosols present in the atmosphere. This study mainly aims to study the characteristics of SSA at 388nm wavelength (UV region) at global scale using Ozone Monitoring Instrument (OMI) (level-3) data which is on board the NASA Aura. The study is carried out for the period 2014 December to 2015 November. The Global region is divided into six sub-regions i.e., North-West, South-West, North, South, North-East and South-East. The SSA values for these sub-regions are averaged and analyzed on a seasonal basis. Four seasons have been chosen and the mean SSA of the sub-regions is calculated with respect to them. The sub-region seasonal approach gave a better inference on the aerosol SSA values. The decrease in the SSA values has been observed over the regions where biomass burning generally takes place. The Southern region is showing low SSA values in almost all the seasons than other regions because of the dust activities and biomass burning activities in the African sub-continent. The Californian and Indonesian forest fires also constitute high absorbing aerosols causing low SSA values.
