Abstract
An integrated system approach has been adopted at the Advanced Environment Monitoring Research Center (ADEMRC), Kwangju Institute Science and Technology (KJIST), Korea for the effective monitoring of atmospheric environment utilizing various optical remote sensing methods. A multi-channel LIDAR system has been used since December 2002 to monitor the vertical profile of atmospheric aerosol. Vertical profiles of extinction coefficient, depolarization ratio, and color ratio of atmospheric aerosols are determined from the simultaneous detection of three elastic-backscatter signals and one Raman signal backscattered by atmospheric nitrogen molecules. Ground based sunphotometer measurement provides LIDAR validation and information on the column integrated aerosol optical depth at seven different wavelengths. Optical atmospheric environment monitoring over horizontal path is also made with a Long-path DOAS system and a transmissometer. The GIST long-path DOAS system has been used to measure concentration of trace gases as well as atmospheric extinction at 550 nm. Results of aerosol optical depth determination based on satellite data retrieval are compared with the results of LIDAR and sunphotometer measurements. This paper presents the results of integrated measurements of atmospheric aerosol at Gwangju (35°10`N, 126°53`E), Korea.
