[ABSTRACT]A PREDE POM-02 skyradiometer (SKYNET) has been installed in May 2008 at Chinese Academy of Meteorological Sciences (116.32°E, 39.93°N, 106.0 m) in Beijing, China to measure the aerosol optical properties. Both the version 4.2 and 5.0 of SKYRAD.pack code have been used to retrieve the columnar aerosol features. The intercomparison results of the aerosol optical properties from version 4.2 and 5show that aerosol optical depth (AOD) has good consistence each other. Single scattering albedo values from version 5 is lower than those from version 4. 2 systematically, but there have good consistence with R-square about 0.85. This difference of SSA suggests that more strict cloud screening implementation should be used in future. The volume size distribution from version 5 has been improved much comparing with that from version 4.2, especially for the coarse mode particles. The aerosol optical properties at Beijing during May, 2008 to October, 2012 including monthly means of AOD, SSA, volume size distribution, refractive index have been analyzed. The elementery results show AOD is higher during spring and summer seasons but lower in fall and winter seasons. SSA is lower during fall and winer season but higher during spring and summer seasions which indicates the aerosol particles have more absorption in winter than summer. This reflects the aerosol chemical composition of Beijing has significant distribution characteristics. Large coarse mode volume size distribution in spring at Beijing reprensent the dust aerosol particle contribution.
