Abstract

Continuous and near-real-time measurements of BC were made for a period of two years from the I-LARC (ISRO Laboratory for Aerosol Radiation and Chemistry) station in Port Blair as a part of the ISRO Geosphere Biosphere Programme (I-GBP). These are used to characterize BC, for the first time over the Bay of Bengal (BoB), which is surrounded by distinct landmasses having highly varying anthropogenic activities. Significantly high concentrations (~2.4 μg m^-3) occur during the period September to April. During this period, BC contributes ~ 6.5 % to the composite aerosol mass concentration. The concentration and its share to the composite aerosols decrease rapidly (by a factor of >3) and remain so during the period June to August when the station is under the influence of monsoon winds coming from the Indian Ocean. Back-trajectory analyses reveal five potential advection pathways, which are seasonal in nature and have a strong influence on the BC concentrations over the island. The results and their implications will be discussed.
