Black Carbon (BC) aerosols mass concentration is study at Surat, Gujarat (INDIA), costal region near the Tapi River at the Gulf of Khambhat. Using Satellite data for solar extinction due to Black Carbon (BC) mass concentration data have been collected from the Giovanni site (http://giovanni.gsfc.nasa.gov/giovanni/) developed by NASA. Results of the data for the 5-year period (January to December 2001-2005) have been discussed here. Annual and Seasonal variations of black carbon (BC) in relation to changes in the regional meteorological conditions. The data collected during January to December 2001-2005 indicated that annual average BC concentration. The mean annual variations of BC aerosols mass concentration seen the maximum in the month of December while minimum in the month of July. The seasonal mean BC mass concentration is lowest observed in monsoon while highest in winter at the study region. Variation of BC trend observed higher in the month December and lower in the month July which is mostly related to the changes in the local boundary layer.
