Differential absorption lidar technique for measurement of the atmospheric pressure profile
Applied Optics, 1983A new two-wavelength lidar technique for remotely measuring the pressure profile using the trough absorption region between two strong lines in the oxygen A band is described. The theory of integrated vertical path, differential ranging, and horizontal path pressure measurements is given with methods to desensitize and correct for temperature effects ...

Infrared differential absorption Lidar (DIAL) measurements of hydrocarbon emissions
Journal of Environmental Monitoring, 2011We report the application of an infrared (IR) differential absorption Lidar (DIAL) system (also capable of ultra violet measurements) built at the National Physical Laboratory (NPL), UK, to field measurements of total site emissions (controlled and fugitive) from petrochemical and landfill installations.

Range-resolved differential absorption lidar: optimization of range and sensitivity
Applied Optics, 1985A practical range-resolved differential absorption and scattering lidar has been optimized for maximum range and sensitivity. Compression of the signal amplitude dynamics, quasi-simultaneous dual-pulse operation, the processing sequence of the primary signals, a method of alignment mismatch compensation, and the effects of temporal and spatial ...

Atmospheric tomography using differential absorption lidar
SPIE Proceedings, 1997Differential Absorption Lidar measurements from a satellite platform are more complex and can yield more information than terrestrial DIAL measurements because of the significant Doppler shift associated with high satellite velocity relative to the atmosphere. This Doppler effect can be exploited as an extra degree of freedom in matching laser lines to

Differential Absorption Lidar Measurements of Atmospheric Species
Topical Meeting on Optical Techniques for Remote Probing of the Atmosphere, 1983Interest in remote measurements of atmospheric gases has gained increased emphasis in recent years because of the need to assess the impact of man's activity on his environment. It has been recognized that knowledge of the sources, sinks, transport, and chemistry of atmospheric species must be obtained over large scales to understand the balance ...

Differential Absorption LiDAR for NASA Ozone Mapping
Knowing how much and where ozone is in our atmosphere is important to daily life on Earth. Ozone present in the stratosphere is critical to protecting life from harmful radiation, but ozone in the troposphere is detrimental. NASA has created a network specifically tasked with measuring and mapping the ozone in the troposphere.Jeremiah Hashley, Lisa Mueller

Signal-induced fluorescence in photomultipliers in differential absorption lidar systems
Applied Optics, 1999Signal-induced bias (SIB) superimposed on the tail of lidar signals detected by photomultiplier tubes (PMT's) has long been recognized as significant interference in lidar data retrieval. Analysis of the data from a lidar transmitting in the horizontal direction revealed that SIB is a well-shaped pulse and is thus called a signal-induced pulse (SIP ...
