Atmospheric tomography using differential absorption lidar

SPIE Proceedings, 1997
Differential 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, 1983
Interest 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.

Signal-induced fluorescence in photomultipliers in differential absorption lidar systems

Applied Optics, 1999
Signal-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 ...
