The CALIPSO Automated Aerosol Classification and Lidar Ratio Selection Algorithm
Descriptions are provided of the aerosol classification algorithms and the extinction-to-backscatter ratio (lidar ratio) selection schemes for the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) aerosol products. One year of CALIPSO level 2 version 2 data are analyzed to assess the veracity of the CALIPSO aerosol-type identification algorithm and generate vertically...
متن کاملSelection algorithm for the CALIPSO lidar aerosol extinction-to- backscatter ratio
The extinction-to-backscatter ratio (Sa) is an important parameter used in the determination of the aerosol extinction and subsequently the optical depth from lidar backscatter measurements. We outline the algorithm used to determine Sa for the Cloud and Aerosol Lidar and Infrared Pathfinder Spaceborne Observations (CALIPSO) lidar. Sa for the CALIPSO lidar will either be selected from a look-up...
متن کاملStatus and performance of the CALIOP lidar
The Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP) is the primary instrument on the CALIPSO satellite, which is scheduled to launch in 2005. CALIOP will provide profiles of total backscatter at two wavelengths, from which aerosol and cloud profiles will be derived. The instrument also measures the linear depolarization of the backscattered return, allowing discrimination of cloud pha...

متن کاملLidar measurements of aerosol depolarization ratio
Lidar measurements of the aerosol depolarization ratio provide highly reliable informations to discriminate between spherical and non-spherical particles in the atmosphere and they can help to distinguish between liquid and solid phase aerosols. These measurements can be performed by using a linearly polarized laser source and a hardware configuration of the receiving system including two chann...
