Paper Abstract

The distributions of aerosol and planetary boundary layer (PBL) heights are presented from CALIOP/CALIPSO (Cloud- Aerosol Lidar with Orthogonal Polarization) and ground-based lidar measurements. We initially assess the approach of using the MODIS-retrieved aerosol optical depth over ocean to constrain lidar-ratio (extinction-to-backscatter ratio) and extinction profile at wavelength 532-nm. Statistical comparisons of cloud and aerosol layers are performed with the 20- day cases. We find in general excellent correlations exist between both cloud-base and top even for multiple deck cases that are not to close. In the clear skies, the CALIPSO-derived aerosol-layer-tops are consistent with ground-lidar derived PBL heights although the accuracy degrades if capped by cloud layers. In addition, PBL heights are derived from the CALIPSO level-1B profiles and mapped over the continental US. Finally, we perform a detailed comparison for a smoke plume event including aerosol classification, derivation of extinction profile and lidar ratio.
