Ocean subsurface studies with the CALIPSO spaceborne lidar

Aerosol Retrievals from CALIPSO Lidar Ocean Surface Returns

This paper describes approaches to retrieve important aerosol results from the strong lidar return signals that are received by the space-borne CALIPSO lidar system after reflecting off-ocean surfaces. Relations, from which the theoretically expected values of area under ocean surface returns can be computed, are presented. A detailed description of the lidar system response to the ocean surfac...

The CALIPSO mission: Spaceborne lidar for observation of aerosols and clouds

Current uncertainties in the effects of aerosols and clouds on the Earth radiation budget limit our understanding of the climate system and the potential for global climate change. The CALIPSO satellite will use an active lidar together with passive instruments to provide vertical profiles of aerosols and clouds and their properties which will help address these uncertainties. CALIPSO will fly ...

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...

Airborne and Spaceborne Lidar

The evolution of lidar, from those early ground-based measurements to our first long-duration spaceborne experiments, is schematically represented in Fig. 13.1. It depicts the first lidars in the 1960s as ground-based, followed by systems first flown in 1969 on small aircraft, and followed in the late 1970s by lidars flown on large aircraft capable of long-range measurements. Starting in 1979, ...
