CALIPSO polar stratospheric cloud observations: second-generation detection algorithm and composition discrimination

CALIPSO/CALIOP Cloud Phase Discrimination Algorithm

The current cloud thermodynamic phase discrimination by Cloud-Aerosol Lidar Pathfinder Satellite Observations (CALIPSO) is based on the depolarization of backscattered light measured by its lidar [CloudAerosol Lidar with Orthogonal Polarization (CALIOP)]. It assumes that backscattered light from ice crystals is depolarizing, whereas water clouds, being spherical, result in minimal depolarizatio...

Polar Stratospheric Clouds over 1 Antarctica from the CALIPSO

1 2 This paper presents statistics of Polar Stratospheric Clouds (PSCs) above Antarctica from 3 June to October 2006 using observations from the CALIOP spaceborne lidar, part of the 4 CALIPSO mission. Synoptic-scale changes in their geographic and temporal distribution 5 are documented on a weekly basis and correlated with temperature fields. A very high 6 spatial and temporal variability tends...

CALIPSO observations of stratospheric aerosols: a preliminary assessment

We have examined the 532-nm aerosol backscatter coefficient measurements by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) for their use in the monitoring of stratospheric aerosol. CALIPSO makes observations that span from 82 S to 82 N each day and, for each profile, backscatter coefficient values reported up to ∼40 km. The possibility of using CALIPSO for stra...
