Abstract

This paper systematically discussed the three-wavelength dual differential absorption lidar (dual-DIAL) method for measuring the stratospheric and tropospheric ozone profiles in the presence of high loading or inhomogeneous aerosols along the measurement path. Results of theoretical analysis and comparisons with DIAL and aerosol correction method show that the three-wavelength dual-DIAL method not only can greatly reduce the effect of aerosols on tropospheric and stratospheric ozone measurements, but also can get more accurate ozone profiles than DIAL after aerosol correction. The system error of three-wavelength dual-DIAL due to aerosols is kept in a low level. As the system error in the three-wavelength dual-DIAL is almost insensitive to the spatial inhomogeneity of aerosol loading and aerosol optical properties, this method does not need to known the detailed information about the spatial distribution of aerosol loading and aerosol optical properties. In the regions contained high loading or inhomogeneous aerosols, accurate ozone profile can be obtained directly from the lidar return signals with three wavelengths dual-DIAL method. Experimental results indicate the three wavelengths dual- DIAL method is effective.
