In this paper the effects of aerosol on tropospheric ozone measurements by three-wavelength (266-289-308nm) dual differential absorption lidar (DIAL) and two-wavelength (266-289 nm and 266-308 nm) DIAL are simulated.B...In this paper the effects of aerosol on tropospheric ozone measurements by three-wavelength (266-289-308nm) dual differential absorption lidar (DIAL) and two-wavelength (266-289 nm and 266-308 nm) DIAL are simulated.By using the two kinds of DIAL.vertical profiles of ozone density from 2 to 3.6 km altitude range are measured.Both simulation and observation results show that the three-wavelength dual-DIAL method is more effective to reduce the effects of aerosol than the two-wavelength DIAL method.Therefore,accurate ozone density distributions can be retrieved by the three wavelength dual DIAL method.展开更多
