LITE-the first spaceborne lidar

Conference Proceedings Second Topical Symposium on Combined Optical-Microwave Earth and Atmosphere Sensing, 2002
The first lidar in Earth orbit was recently flown aboard the Space Shuttle Discovery, September 9-20, 1994. The lidar In-space Technology Experiment (LITE) collected 45 hours of 3-wavelength atmospheric backscatter profiles during the 10-day mission. A wide variety of lidar measurements were made, including those of multi-level clouds, tropospheric and

Quantifying Surface Reflectivity for Spaceborne Lidar Missions

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Spaceborne lidar missions are being studied to estimate atmospheric concentrations of CO2, water vapour and O3, as well as for measuring surface biophysical properties. Lidar instruments typically observe the highest possible surface reflectance due to observing in the retroreflection peak (the so-called 'hotspot'), where shadowing on the surface is ...

Spaceborne scanning lidar system (SSLS)

SPIE Proceedings, 2005
The Spaceborne Scanning Lidar System (SSLS) system is a space qualified scanning lidar system developed by MDA, Space Missions (MD Robotics) and Optech. It is scheduled to be launched in 2005 as part of a one year on-orbit demonstration of space technologies associated with spacecraft autonomous rendezvous and proximity operations.

Cloud parametrization for spaceborne lidar applications

SPIE Proceedings, 1998
This paper discusses a cloud parameterization scheme for lidar application to cloud measurements by a space-borne lidar system. In lidar measurements generally the information on cloud particle size and number density is not available. Therefore, cloud parameterization becomes essential to derive from lidar observations the cloud optical parameters ...

Spaceborne Lidar Mission, Past and Future

Conference on Lasers and Electro-Optics Europe, 1996
Laser rangefinders and atmospheric lidars use the same techniques. A short laser puls is transmitted and the reflected or scattered light is detected. Range resolved information of the targets or scatters is the output. To illustrate the use the mission, an example for a ground based system is given: A mission scenario on the highways is a good example.

Simulation of the aerosol spaceborne lidar Tectonica-A

SPIE Proceedings, 1999
The aim of the project `Tectonica-A' is the development of the technique and the creation of a spaceborne lidar for determining the sites of enhanced concentration of surface aerosols. The lidar data combined with the data of different sensors (spaceborne and ground-based) will be used for the short-term forecast of the earthquakes.

Modern concept of a spaceborne lidar

SPIE Proceedings, 1999
The experience on the first backscatter lidar operating in space (LITE, USA, 1994; BALKAN, Russia, 1995 - 1997; ALISSA, Russia-France, 1996 - present time) is analyzed to provide a basis for guiding the development of new orbital lidars. Considering the status of development of laser sensing methods harnessing elastic scattering and needs for obtaining

Development of spaceborne LIDAR; ELISE (Experimental Lidar In Space Equipment)

Technical Digest. CLEO/Pacific Rim '99. Pacific Rim Conference on Lasers and Electro-Optics (Cat. No.99TH8464), 2003
The National Space Development Agency of Japan (NASDA) started a study on spaceborne lidar in 1990, and has developed a ground-based and an airborne lidar. Now they are to embark on the ELISE (Experimental Lidar In Space Equipment) which is the two-wavelength spaceborne backscatter lidar which will be loaded onto Mission Demonstration test Satellite-2 (

Simulation and assessment of solar background noise for spaceborne lidar

Applied Optics, 2018
The properties for six typical land cover types and three sky conditions were derived in this paper, which allows to make seasonal upper estimations of solar background radiation for a given atmospheric scenario. Solar background noise can be derived from the estimations for a spaceborne lidar based on optical parameters.

Effect of multiple scattering on depolarization measurements with spaceborne lidars

Applied Optics, 2003
An analytical model based on the integration of the scattering-angle and light-path manifold has been developed to quantify the effect of multiple scattering on cirrus measurements obtained with elastic polarization lidars from space. Light scattering by molecules and by a horizontally homogeneous cloud is taken into account. Lidar parameter, including
