中文摘要:
      模拟了气溶胶影响三波长双差分(266-289-308nm)方法和双波长差分(266-289nm和266-308nm)方法测量对流层臭氧的误差,并在合肥测量了对流层2~3.6km高度的臭氧分布.结果表明,三波长双差分方法比常规的双波长差分方法能更有效地克服气溶胶的影响,三波长差分测量的结果比常规的双波长差分的结果更精确.同时还揭示了气溶胶影响双波长差分方法测量臭氧的规律.模拟结论与测量结果是一致的.
英文摘要:
      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)diferential absorption lidar are simulated and ozone profiles from 2 to 3.6 km altitude at Hefei are measured.Reults 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-wave-ength dual-DIAL method.In the meantime,the laws of aerosol effects are foum don DIAL measurements in tropospheric ozone.Measurement results show great agreement with simulation conclusions.
