Retrieval of ocean subsurface particulate backscattering coefficient from space-borne CALIOP lidar measurements

Lidar Backscattering Measurements of Background Stratospheric Aerosols

Subsurface Ocean Signals from an Orbiting Polarization Lidar

Detection of subsurface returns from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) on the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite were demonstrated. Despite the coarse range resolution of this aerosol lidar, evidence of subsurface scattering was observed as a delay and broadening of the cross-polarized signal relative to the co-polar...

Shape-induced gravitational sorting of Saharan dust during transatlantic voyage: Evidence from CALIOP lidar depolarization measurements

[1] Motivated by the physical picture of shape-dependent air resistance and, consequently, shape-induced differential sedimentation of dust particles, we searched for and found evidence of dust particle asphericity affecting the evolution and distribution of dust-scattered light depolarization ratio (d). Specifically, we examined a large data set of Cloud-Aerosol Lidar with Orthogonal Polarizat...

Retrieval of particulate backscattering in coastal/oceanic waters

Accurate retrieval of particulate backscattering coefficients has been a great challenge in optically complex Case 2 waters. Although several models exist for retrieval of the Inherent Optical Properties (IOP’s) such as particulate backscattering (bbp) from the remote sensing reflectance, these models produce bbp with high errors mainly because of improper parameterization or inappropriate defi...

Status 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...
