Abstract: The results of two years of laser radar observations, of the mesosphere and lower thermosphere over Kingston, Jamaica (18.0N, 76.8W), are described. These show the existence of a clear annual variation in atmospheric density ...

Abstract: The laser radar system at Kingston, Jamaica (189N, 17°W) has been used to study periodic variations in atmospheric density at altitudes between 68 and 100 km. A major feature of these variations is an oscillation with a ...

Abstract: Lidar observations of the stratosphere were made at Kingston, Jamaica (18.0°N, 76.8°W) following the eruptions of the Soufrière volcano of St. Vincent (13.2°N, 61.2°W) between 13 and 23 April 1979. Anomalous optical ...

Abstract: Remote sensing of the lower atmosphere by lidar yields profiles of the backscattering cross section along the optical path. These may be simply converted to give a qualitative picture of the distribution of atmospheric ...

Abstract: A brief discussion of the laser-radar method for investigating atmospheric properties above the troposphere is given. A detailed description is then presented of a large new system which has been constructed in Jamaica. ...

Abstract: This paper describes equipment designed to observe variations in atmospheric density at heights up to 65 km by measuring the intensity of light back-scattered from a laser beam. The basic theory of the technique is briefly ...

Abstract: Results are presented from an intensive study of the stratospheric aerosol layer over Kingston, Jamaica, made in 1978?79, using a ruby lidar system. The aerosol layer is found to extend up to an altitude of about 35 km, ...

Abstract: Airborne lidar measurements of backscattering at 0.6943 ?m from polar stratospheric clouds, made in January 1984, are reported. The clouds, whose altitudes and geographical locations coincided with ambient atmospheric ...

Abstract: The SAGE-I and SAM-II satellite sensors were designed to measure, with global coverage, the 1 ?m extinction produced by the stratospheric aerosol. In the absence of high altitude clouds, similar measurements may be made ...

Abstract: Aerosol extinction data obtained by the Stratospheric Aerosol Measurement II (SAM II) satellite instrument during the 1979/80 Northern Hemisphere winter season have been analyzed in relation to the cyclonic polar vortex. ...
