Abstract

Extensive measurements of the mass concentrations of BC and composite aerosols were made for the first time during the inter-monsoon and summer monsoon seasons (March to June, 2003) over coastal Arabian Sea region under the Arabian Sea Monsoon Experiment (ARMEX). Results showed a gradual and continuous decrease (by a factor of 7) in the mean concentration of BC from ~700 ng m-3 in March to reach as low as ~ 104 ng m-3 in June. The diurnal variations were very weak during March, weakened progressively and almost vanished by May and June. Consistent with this, there is a rapid decrease in the share of BC to the composite aerosol system.
