摘要: The three-dimensional structure and the optical properties of Indian pollution plume has been investigated from airborne LIDAR radiometric measurements over Ocean during three consecutive days (7, 8, 9 March 1999) INDOEX'99 intensive field phase. vertical consisted two layers: marine atmospheric boundary layer (MABL) so-called land aloft. depth was observed to depend on history air masses; shallow plumes were associated with masses coming Gulf Bengal, while deeper subcontinent. larger aerosol depths (AODs) Meteosat-5 Arabian Sea plume. A combination light detection ranging (LIDAR) Sun photometer at Kaashidhoo Observatory in Male used determine column-equivalent backscatter-to-extinction ratio needed retrieve extinction coefficient profiles AOD measurements. Direct forcing analyzed using a simple radiative model as well LIDAR-derived visible flux Average values vertically integrated single scattering albedo about 0.85 ± 0.05 0.8 0.1 found be shallower part plume, respectively., Characterization spatial distribution radiometry INDOEX'99,
