内容 研究概要:Representative sets of the extinction-to-backscattering ratio for several wavelengths from the actual measurements would contribute to extract more substantial information from remotely sensed aerosol data. Here we propose a method to determine the extinction-to-backscattering ratio using a multi-wavelength lidar (1064, 532, 756, and 355nm) and a sun photometer data. In our approach, first, the ratio is obtained at 532nm by comparing the optical thickness derived from the lidar data with optical thickness obtained with the sun photometer. At each altitude, it is assumed that the aerosol extinction coefficient at each lidar wavelength is proportional to the coefficient at 532nm. The proportional factors are obtained from the sun photometer data. Then we determine the value of the ratio at 1064, 756, and 355nm using the profile as a reference profile.
