Comparison of lidar measurement with balloonborne OPC measurement over Bandung, Indonesia

For the study of stratospheric aerosol over the Tropics, balloon-borne OPC measurements have been made six times from April 1997 to March 2000 at Bandung, Indonesia (6.9 deg S, 107.6 deg E)where Lidar measurements have also been made since early 1997. Correlative measurements of Lidar and OPC were conducted on March 25, 1998 and August 23, 1999. Results of the latter measurement were compared in this paper. The profile of back scattering ratio measured by Lidar almost represents a vertical distribution of small particles having radii smaller than 0.4 μm. We calculated back scattering coefficients from the results of OPC measurement. The calculated and measured back scattering coefficients were not consistent completely but not so unreasonable.
