| Abstract: | In this paper the effects of aerosol on tropospheric ozone measurements by three-wavelength(266-289-308 nm) dual differential absorption lidar (DIAL) and two-wavelength(266-289 nm and 266-308 nm) differential absorption lidar are simulated and ozone profiles from 2 to 3.6 km altitude at Hefei are measured. Results show that the the three-wavelength dual-DIAL method is more effective to reduce the effects of aerosol than the two-wavelength DIAL method, and more accurate ozone density can be obtained by the three-wavelength dual-DIAL method. In the meantime, the laws of aerosol effects are foumd on DIAL measurements in tropospheric ozone. Measurement results show great agreement with simulation conclusions. |
