Abstract :
The stable aerosol retrieval algorithm needs a prior assumption of lidar ratio (the extinction-to-backscatter ratio), and the known aerosol type that is the prerequisite of this assumption, so how to identify the clouds and aerosol from lidar profile is fundamental to acquire atmospheric optical parameter. In this paper, we first employ the CloudSat to validate the CALISPO´s classificatory results, which is released in different versions, after choosing more accurate classification, then start retrieving. Second, sun-photometer is used for verifying the CALIPSO´s calibration coefficient and supplies the day time records which are relatively more accurate. Finally, aerosol characteristic in Hubei province is analyzed. All the data will supply more available information for further climate change research.
