Book excerpt: Jens Bosenberg Max-Planck-Institut fur Meteorologie, Bundesstr. 55, D-20146 Hamburg, Germany TESLAS, which stands for Tropospheric Environmental Studies by Laser Sounding, was formed in November 1987 as a subproject of EUROTRAC to enhance the measurement capabilities for vertical profiling of ozone in the troposphere by means of laser remote sensing. For studies of several atmospheric processes related to the formation and redistribution of photo-oxidants there was a clear need for measuring extended time series with appropriate vertical and temporal resolution. These could not be obtained by conventional in situ techniques, at least not with affordable effort, so remote sensing appeared to be the best way to obtain the required information. At the beginning of the subproject, some Differential Absorption Lidar (DIAL) systems for measuring the vertical distribution of ozone already existed, but their use was restricted to very few laboratories and very few measurement campaigns, since the instruments were highly complex, rather unreliable, and required extensive efforts for maintenance and operation by skilled scientists. In addition, the accuracy of these measurements under a variety of meteorological conditions was not really well established. The main tasks within TESLAS therefore were to develop fully the DIAL-methodology for remote sensing of tropospheric ozone, and to develop instruments which are accurate, reliable, easy to operate, and suitable for field deployment or airborne operation.

This book was released on 2018-09-20 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote airborne measurements of the vertical and horizontal structure of the atmospheric pressure field in the lower troposphere are made with an oxygen differential absorption lidar (DIAL). A detailed analysis of this measurement technique is provided which includes corrections for imprecise knowledge of the detector background level, the oxygen absorption fine parameters, and variations in the laser output energy. In addition, we analyze other possible sources of systematic errors including spectral effects related to aerosol and molecular scattering interference by rotational Raman scattering and interference by isotopic oxygen fines.Flamant, Cyrille N. and Schwemmer, Geary K. and Korb, C.

Download or read book Advances in Atmospheric Remote Sensing with Lidar written by Albert Ansmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lidar or laser radar, the depth-resolved remote measurement of atmospheric parameters with optical means, has become an important tool in the field of atmospheric and environmental remote sensing. In this volume the latest progress in the development of Lidar methods, experiments, and applications is described. The content is based on selected and thoroughly refereed papers presented at the 18th International Laser Radar Conference, Berlin, 22 - 26 July 1996. The book is divided into six parts which cover the topics of tropospheric aerosols and clouds, Lidar in space, wind, water vapor, troposheric trace gases and plumes, and stratospheric and mesospheric profiling. As a supplement to fundamental LIDAR textbooks this volume may serve as a guide through the blossoming field of modern Lidar techniques.
Download or read book Optical and Laser Remote Sensing written by D.K. Killinger and published by Springer. This book was released on 2013-06-29 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of optical and laser remote sensing has grown rapidly in recent years. This dynamic growth has been stimulated not only by technological advances in lasers, detectors, and optical system design, but also by the potential application of remote sensing systems to a wide variety of atmo spheric measurements. Optical and laser remote sensing can allow single ended measurement capability not offered by conventional point-detection techniques. While many past measurements have been associated with labo ratory research. practical systems have recently been developed which are capable of remotely detecting. measuring. and tracking a wide range of molecular and atomic species in the atmosphere with concentrations of parts per billion and at ranges over 100 km. This book is a compilation of papers which represent an overview of the present state of development of optical and laser remote sensing tech nology. The subjects covered include both passive and active remote sen sing techniques in the UV, visible, and IR spectral regions. related laser and detector technology, and atmospheric propagation and system analysis considerations. While the papers do not constitute an exhaustive treat ment of the excellent research being conducted in this field, they are representative of the wide diversity of present efforts. It is hoped that the reader will gain a general understanding of the current research in optical and laser remote sensing as well as an overview of current systems development.
Download or read book Tunable Solid State Lasers for Remote Sensing written by Robert L. Byer and published by Springer. This book was released on 2013-06-29 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Workshop on Tunable Solid State Lasers for Remote Sensing was held at Stanford University in October 1984 to assess the state of the art in tunable solid state lasers for remote sensing from satellite platforms. The value of conducting global remote sensing measurements of atmospheric chemistry, climate, and weather in the 1990s is now established. What is not yet defined, however, is the status of the developing tunable laser technology that must meet both the scientific requirements and the space platform constraints. This workshop was convened by the Office of Aeronautics and Space Technology (OAST) of the National Aeronautics and Space Administration (NASA) to assess the status and progress in tunable solid state laser sources for remote sensing. The workshop was organized to facilitate information exchange across a number of technologies from remote sensing requirements to crystal growth of the materials important for the development of the tunable laser sources. The emphasis was on the recent developments in tunable solid state laser sources necessary to meet the future transmitter requirements for global remote sensing. A goal of the workshop was to form recommendations to NASA on the current and future prospects for solid state laser technology that will allow remote sensing measurements from air, shuttle, and free-flying satellite platforms. The emphasis was on solid state laser sources because they offer the best potential for meeting the demanding requirements of compact size, good efficiency, and long operational lifetimes required for future space station and free-flying platform operation.

Book excerpt: In recent years there has been renewed interest in the scientific and indu strial communities in tunable solid state vibronic lasers. Much of this has been spurred by the user desirous of obtaining compact primary laser sources (independent of nonlinear optical frequency shifts) throughout the visible and near infra-red spectral regi ons. To further motivate and stimul ate re search and development in this area, workshops sponsored by the Laser Divi sion of the US ArmY Night Vision Electro-Optics Laboratory (NVEOL) at Fort Belvoir, Virginia were held during 1-3 April 1981 and 16-17 June 1983 at Keystone and NVEOL, respectively. The consensus of opinion of the partici pants at these workshops was that any successful program leading to the iden tification and development of vibronic tunable laser materials in the visible and IR must include coordinated activity between crystal growers, theoreti cal and experimental investigators into the fundamental processes of vibro nic lasing, and laser device engineers. Continued interaction between govern ment, industry, and academia was encouraged in order to establish a unified approach to these areas and, when necessary, redefine and redirect program matic activity. The organization of this 1st Annual Conference on Tunable Solid State La sers held at the La Jolla Institute 13-15 June 1984, was based around the latest results in tunable vibronic materials and laser development, but structured ina manner consi stent wi th the recommendati ons of the NVEOL workshops.
