Article Preview

The aerosol comparison experiment was conducted in the Semi-Arid Climate and Environment Observatory of Lanzhou University since March to April 2007 with the measurements of two micro-pulse lidars MPL-4B and CE370-2. In the paper, the differences of aerosol extinction coefficient and optical depth retrieved from the observations of MPL-4B and CE370-2 are analyzed, and the results show: the aerosol extinction coefficient retrieved from the observation of MPL-4B is in general smaller than that from CE370-2, and the difference mainly exists in the low layer, while their trends of vertical profiles agree well; the aerosol optical depths from the observations of MPL-4B and CE370-2 correlate linearly rather well with the coefficient of 0.71, and the aerosol optical depth retrieved from the measurement of MPL-4B is less than that from CE370-2 in whole.
