Aerosol monitoring program of Ground Based Atmosphere-Observation Network in Korea

In NE Asia including Korea, Asian-dust (yellow sand) fall out phenomena during spring are of great importance. Satellite and ground based stations are required that can provide high accuracy with high spatial and temporal resolution data. In Korea, optical measurement methods were first tried at the beginning of 1980. Lidar methods were first used during the early 1990s. At present, some groups are measuring ozone and aerosol using the lidar, ozonesonde and spectrometer. For ozone and aerosol remote sensing, the Ground-Based Atmosphere-Observation Network (GBANK) is the collaboration research program between Korea-NASA in 1997. GBANK is organized with 8 groups with sites of 3 lidar, 3 spectrometer, 4 sun photometer and 1 ozone sonde. GBANK´s main goals are product of high quality standard database of aerosol and ozone over Korean peninsular.
