“…Thus, surface losses can generally be neglected, although the surface return can be quite large. 13,28,29 Neglecting the effects of multiple scattering, the depth-dependent lidar signal can be described by the lidar equation.…”

This paper provides a review of the development of profiling oceanographic lidars. These can provide quantitative profiles of the optical properties of the water column to depths of 20 to 30 m in productive coastal waters and to depths of 100 m for a blue lidar in the open ocean. The properties that can be measured include beam attenuation, diffuse attenuation, absorption, volume scattering at the scattering angle of 180 deg, and total backscattering. Lidar can be used to infer the relative vertical distributions of fish, plankton, bubbles, and other scattering particles. Using scattering as a tracer, lidar can provide information on the dynamics of the upper ocean, including mixed-layer depth, internal waves, and turbulence. Information in the polarization of the lidar return has been critical to the success of many of these investigations. Future progress in the field is likely through a better understanding of the variability of the lidar ratio and the application of high-spectral-resolution lidar to the ocean. Somewhat farther into the future, capabilities are likely to include lidar profiling of temperature in the ocean and an oceanographic lidar in space.

“…The ocean surface reflectance depends on the (10-m height) surface wind speed. The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission provides by far the largest study of lidar backscatter from the ocean surface, and we rely on data from Hu et al (2008) for determination of the surface directional reflectance (backscatter) over this region of the Pacific Ocean. We are able to take advantage of the fact that at the JPL LAS nominal 58 off-nadir angle, the surface backscatter is only weakly dependent on surface wind speed in the range from ;(2.5-12) m s 21 (see Menzies et al 1998, their Figs.…”

This paper provides atmospheric CO 2 column abundance measurement results from a summer 2011 series of flights of a 2.05-mm laser absorption spectrometer on the NASA DC-8 research aircraft. The integrated path differential absorption (IPDA) method is used for the CO 2 column mole fraction retrievals. This instrument and the data analysis methodology developed to achieve retrievals over complex terrain and variable atmospheric conditions provide insight into the capabilities of the IPDA method for both airborne measurements and future global-scale CO 2 measurements from low-Earth orbit pertinent to the proposed NASA Active Sensing of CO 2 Emissions over Nights, Days, and Seasons (ASCENDS) mission. Demonstrated in this paper is the capability to measure CO 2 drawdown caused by crop activity during a midday flight over the U.S. upper Midwest area. In addition, an example is provided of high spatial resolution measurements of CO 2 plumes from individual stack clusters of the Four Corners Power Plant in northwestern New Mexico. Complex terrain, the spectral properties of the aboveground scatterers, and potential cloud contamination are factors that complicate the column abundance retrieval. The impacts of these factors and various means of minimizing these influences in the retrievals are discussed.

“…Figure 9 shows model results from a TMFL instrument for various wind speeds taken at 2000 ft above water level. The model 19 predicts the relationship between the variance of the slope of the wind-driven waves and surface wind speed. Such studies have shown good agreement using CALIPSO lidar data.…”

The Topographic Mapping Flash Lidar (TMFL) developed at Ball Aerospace combines a pushbroom format transmitter at 1064 nm with a flash focal plane receiver. The wide 20 degree field of view of the instrument enables broad swath coverage from a single laser pulse without the need for a scanning mechanism. These features make the TMFL design particularly well-suited for space flight. TMFL has been demonstrated during an airborne flight where data were gathered over a forest plot to measure tree waveforms. Topographic maps were assembled of river beds and geologic areas of high relief. The TMFL has also been used to observe multiple-scattering phenomena in clouds by illuminating a steam plume from the aircraft above. Signal was recorded off-axis from the illuminated laser line by as much as 1 degree. The TMFL study of multiple-scattering is valuable as it provides a unique way to significantly improve the calibration of measured backscatter for space lidars. Lidar backscatter was also measured from water surface and was shown to correlate with models of water surface roughness.
