Brief Description (Abstract):

The properties of marine and Antarctic aerosols, their dependence on meteorological, geographical and human influences are examined using measured spectral aerosol optical depth (AOD), total mass concentration (M T ) and mass concentrations of black carbon aerosol (M B ), in the marine atmospheric boundary layer (MABL) from coastal India and Antarctica and over two distinct coastal locations of Antarctica; Maitri (70.77?S, 11.73?E, 123 m m.s.l.) and Bharati (69.40?S, 76.20?E, 48 m m.s.l.), during southern hemispheric(SH) summer (December to March) of 2007-2008, as a part of the 27 th Indian Antarctic Expedition, during International Polar Year (IPY). Over the oceans, large latitudinal gradients are seen; with AOD decreasing from coastal India (AOD~0.45) to coastal Antarctica (AOD~0.04) during the Northern Hemisphere (NH) winter leg (Dec 2007 to Jan 2008), with a strong seasonality of AOD over all regions, with a decrease of the values and gradient in NH spring (Mar-Apr 2008).

Status: Completed

Purpose: we examined the spatial gradients in the optical and physical properties of aerosols and their seasonality over distinct oceanic regions between coastal India to Antarctica and over the Indian stations, Maitri and Bharati in the coastal East Antarctica, based on measurements carried onboard the ship cruise of 27th Indian Antarctic Expedition, during the International Polar Year (IPY) 2007-2008.
