Attention is given to the differential absorption lidar technique used in measuring the vertical ozone distribution of the troposphere and stratosphere. The basis of these measurements are UV wavelength range laser sources which encompass Nd:YAG pumped dye lasers and Exciplex lasers. High temporal and spatial resolution, together with measurement c...

I föreliggande rapport har punkt- och linjemätningar av luftföroreningar jämförts dels teoretiskt och dels, då så varit möjligt, genom belysande exempel från praktiska mätningar. Tonvikten i jämförelserna har legat på DOAS, men då ur utvärderingssynpunkt LIDAR-mätningar kan betraktas som en avancerad form av DOAS-mätning, har resultaten, där så var...

Temperature measurements using vibrational Raman scattering from molecular nitrogen were performed simultaneously with temperature obtained by Rayleigh scattering in the amplitude range between 12 and 30 km. The downward extension of the Rayleigh temperature described in this paper leads to the possibility of obtaining a continuous temperature prof...

For approximately one month during October and November 1988 the NASA Goddard Space Flight Center mobile lidar system was brought to the Jet Propulsion Laboratory, Table Mountain Facility, to make side-byside measurements with the JPL lidar of stratospheric ozone concentration profiles. Measurements were made by both excimer laser DIAL systems on f...

Four lidars, located roughly 75 km from each other in the inner German Bight of the North Sea, were used to measure geometrical and optical properties of cirrus clouds during the International Cirrus Experiment 1989 (ICE '89). A complete cirrus life cycle was observed simultaneously with three lidars during a case study on 18 October 1989. Time ser...
In June 1994 the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR) started operation with first measurements by the ALOMAR Rayleigh/Mie/Raman-Lidar (R/M/R-Lidar). The observatory, located on the Andoeya Rocket Range (69 N, 16 E) in northern-Norway, was established as an international research facility comprising active and passive re...
