　　This paper presents the Fog-Haze measurements by Raman-Rayleigh-Mie Lidar in North surbub of Nanjing,the measurement results are analyzed and compared with the weather forecast.Continuous measurents are carried out on 2009/12/2,it is clear day from 01:00 to 08:00 in the morning,and Fog-Haze is measured from at 10:00 in the morning to 19:00 in the evening.The Fog-Haze measurement results coincide with the weather forecast that very day.The Fog-Haze Lidar measurement results on 2009/12/2 are analyzed and compared with the boundary aerosol measurement results on 2010/01/10,the differential characters of range-corrected-signals between Fog-Haze and boundary aerosol are discussed.It is shown that Fog-Haze usually occurs at about 300-400m height and boundary aerosol usually occurs at about 1000m height in Nanjing.
