AB: The aerosol optical depth (AOD) and Angstrom exponent are analyzed based on the CIMEL CE-318 observed data at semi-arid climate and environment observatory of Lanzhou University (SACOL) for the period of August 2006 to July 2007, especially for the period of PACDEX. The result shows that the seasonal variation of AOD is significant. The value of AOD is the highest in Spring and the lowest in Fall, respectively. The Angstrom exponent is the lowest in Spring, indicating that the ratio of larger particles increased due to the dust aerosol. The variability of Angstrom exponent is less in Winter. The surface observed AOD are also compared with the AOD derived from MODIS.
