Book Description
Optical scattering, under very clear atmospheric conditions, was measured in situ and analyzed. The experiments were made with a large balloonborne nephelometer launched from Holloman AFB, New Mexico and flown to 26 km altitude. Profiles of angular scattering and polarization properties of atmospheric aerosols show contrast with aerosol particles encountered in the troposphere and stratosphere. The results are compared with those obtained using particle counters under similar atmospheric conditions.

Book Description
This new text offers experienced students a comprehensive review of available techniques for the remote sensing of aerosols. These small particles influence both atmospheric visibility and the thermodynamics of the atmosphere. They are also of great importance in any consideration of climate change problems. Aerosols may also be responsible for the loss of harvests, human health problems and ecological disasters. Thus, this detailed study of aerosol properties on a global scale could not be more timely.

Book Description
We report in this paper the relevant results obtained for the calculation and the retrieving of the optical properties of the particles that can constitute the atmospheric aerosols. In the first section we present the preliminary results of computations of the optical properties (extinction and backscattering) for low density dispersions of particles with an irregular shape. These particles are modelled as clusters of spheres and the calculated Lidar ratios will be compared with the other computations performed using spheres with Mie theory. The values of the lidar ratio will also constitute the data base for the interpretation of the experimental data obtained with LIDAR systems. In the second section we implemented a neural network that proved to be a useful tool for the recognition of the microphysical properties of a low density dispersion of spherical particles from the angular pattern. In future we plan to extend the algorithm to the recognition of the optical parameters for nonspherical particles. In the third section we have explored the scattering properties of the irregular shaped aerosols by means an angular analysis in the IR-VIS range aimed to compare the calculated scattering patterns with the experimental ones obtained with a two-dimensional angular optical scattering device (TAOS). More extended comments are contained in a paper that will be published in Applied Optics.

Proceedings of the 30th International Laser Radar Conference

Proceedings of the 30th International Laser Radar Conference PDF Author: John T. Sullivan
Publisher: Springer Nature
ISBN: 3031378180
Category : Science
Languages : en
Pages : 825

Book Description
This volume presents papers from the biennial International Laser Radar Conference (ILRC), the world’s leading event in the field of atmospheric research using lidar. With growing environmental concerns to address such as air quality deterioration, stratospheric ozone depletion, extreme weather events, and changing climate, the lidar technique has never been as critical as it is today to monitor, alert, and help solve current and emerging problems of this century. The 30th occurrence of the ILRC unveils many of the newest results and discoveries in atmospheric science and laser remote sensing technology. The 30th ILRC conference program included all contemporary ILRC themes, leveraging on both the past events’ legacy and the latest advances in lidar technologies and scientific discoveries, with participation by young scientists particularly encouraged. This proceedings volume includes a compilation of cutting-edge research on the following themes: new lidar techniques and methodologies; measurement of clouds and aerosol properties; atmospheric temperature, wind, turbulence, and waves; atmospheric boundary layer processes and their role in air quality and climate; greenhouse gases, tracers, and transport in the free troposphere and above; the upper mesosphere and lower thermosphere; synergistic use of multiple instruments and techniques, networks and campaigns; model validation and data assimilation using lidar measurements; space-borne lidar missions, instruments and science; ocean lidar instrumentation, techniques, and retrievals; and past, present and future synergy of heterodyne and direct detection lidar applications. In addition, special sessions celebrated 50 years of lidar atmospheric observations since the first ILRC, comprising review talks followed by a plenary discussion on anticipated future directions.

Book Description
Ein Blick auf die morphologischen, physikalischen und chemischen Eigenschaften von Aerosolen aus den unterschiedlichsten natürlichen und anthropogenen Quellen trägt zum besseren Verständnis der Rolle bei, die Aerosolpartikel bei der Streuung und Absorption kurz- und langwelliger Strahlung spielen. Dieses Fachbuch bietet Informationen, die sonst schwer zu finden sind, und vermittelt ausführlich die Kenntnisse, die erforderlich sind, um die mikrophysikalischen, chemischen und Strahlungsparameter zu charakterisieren, die bei der Wechselwirkung von Sonnen- und Erdstrahlen so überaus wichtig sind. Besonderes Augenmerk liegt auf den indirekten Auswirkungen von Aerosolen auf das Klima im Rahmen des komplexen Systems aus Aerosolen, Wolken und der Atmosphäre. Auch geht es vorrangig um die Wirkungen natürlicher und anthropogener Aerosole auf die Luftqualität und die Umwelt, auf die menschliche Gesundheit und unser kulturelles Erbe. Mit einem durchgängig lösungsorientierten Ansatz werden nicht nur die Probleme und Gefahren dieser Aerosole behandelt, sondern auch praktikable Lösungswege aufgezeigt.

Book Description
The book is divided into two sections. The first section presents characterization of atmospheric aerosols and their impact on regional climate from East Asia to the Pacific. Ground-based, air-born, and satellite data were collected and analyzed. Detailed information about measurement techniques and atmospheric conditions were provided as well. In the second section, authors provide detailed information about the organic and inorganic constituents of atmospheric aerosols. They discuss the chemical and physical processes, temporal and spatial distribution, emissions, formation, and transportation of aerosol particles. In addition, new measurement techniques are introduced. This book hopes to serve as a useful resource to resolve some of the issues associated with the complex nature of the interaction between atmospheric aerosols and climatology.
