Book excerpt: The earth's atmosphere affects the velocity of propagation of microwave signals. This imparts a range error to radar range measurements that assume the typical simplistic model for propagation velocity. This range error is a function of atmospheric constituents, such as water vapor, as well as the geometry of the radar data collection, notably altitude and range. Models are presented for calculating atmospheric effects on radar range measurements, and compared against more elaborate atmospheric models.

Book Synopsis The Measurement of Integrated Refractivity for Evaluating Atmosphere-induced Radar Ranging Errors by : W. G. Tank
Download or read book The Measurement of Integrated Refractivity for Evaluating Atmosphere-induced Radar Ranging Errors written by W. G. Tank and published by . This book was released on 1967 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Line-integrated refractivity is isolated as the basic parameter required for correcting atmosphere-induced radar ranging data errors. A basis for the determination of integrated refractivity from measurements of the absorption or emission of infrared and of microwave radiation by atmospheric oxygen and water vapor, with subsequent interpretation of those measurements in terms of integrated oxygen and water-vapor partial densities, is then established. Both active and passive absorption-measuring systems applicable to the range data-correction problem are described. Finally, examples of integrated oxygen and water-vapor partial densities obtained with active infrared and passive microwave instrumentation of the types described are presented. It is estimated that incorporation of such instrumentation into ranging systems will permit a real-time line-integrated refractivity measurement accuracy of about 1 percent in total line-integrated refractivity.

Book Synopsis Radar for Meteorological and Atmospheric Observations by : Shoichiro Fukao
Download or read book Radar for Meteorological and Atmospheric Observations written by Shoichiro Fukao and published by Springer Science & Business Media. This book was released on 2013-08-16 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epoch-making progress in meteorology and atmospheric science has always been hastened by the development of advanced observational technologies, in particular, radar technology. This technology depends on a wide range of sciences involving diverse disciplines, from electrical engineering and electronics to computer sciences and atmospheric physics. Meteorological radar and atmospheric radar each has a different history and has been developed independently. Particular radar activities have been conducted within their own communities. Although the technology of these radars draws upon many common fields, until now the interrelatedness and interdisciplinary nature of the research fields have not been consistently discussed in one volume containing fundamental theories, observational methods, and results. This book is by two authors who, with long careers in the two fields, one in academia and the other in industry, are ideal partners for writing on the comprehensive science and technology of radars for meteorological and atmospheric observations.
Book Synopsis Atmospheric Effects on Radar Target Identification and Imaging by : H. Jeske
Download or read book Atmospheric Effects on Radar Target Identification and Imaging written by H. Jeske and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Study Institute (ASI) under discussion was initiated by the "Special Programme Panel on Radio meteorology" of the Scientific Affairs Division of NATO. The domain of this panel - and consequently the topics of their former ASI-~rogrammes - is the influ ence of the non-ionized atmosphere on electromagnetic wave propagation, its prediction and its use as a re mote sensing technique. It is the final goal to inform radio and radar engineers about the various defects caused by the propagation medium atmosphere. Today there exist high-sensitive radar systems which can pro vide identification and produce images of distant ob jects very accurately by measuring a) the effect of the target on the shape of a short radar pulse, or b) the wave front (phase and amplitude distribution) and its orientation in space. But usuallv the radar-to-target path is through the inhomogeneous and turbulent atmo sphere and so the absolut limits of the system are very often determined by this atmosphere. It was the plan of this ASI to arrange an interdisciplinary information exchange between radar experts and propagation specia lists in order to get a better understanding of the susceptibility to atmospheric effects and to develope new methods that will reduce or correct these errors. The lectures given and especially the intensive dis cussions during the workshop sessions contributed to this aim.

Book Synopsis Comparison of Radar and In Situ Measurements of Atmospheric Turbulence by :
Download or read book Comparison of Radar and In Situ Measurements of Atmospheric Turbulence written by and published by . This book was released on 2004 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: We compare measurements of refractive index structure constant C (2)(n) and energy dissipation rate e by VHF radar with in situ observations by high-resolution thermosondes during a campaign near Adelaide, Australia, in August 1998. A total of 17 thermosonde soundings was performed within a distance of 120 km to the radar site. The variance between estimates of (C(2)(n)) from backscattered radar power and in situ thermosonde observations is found to be comparable to the observed variance of the radar estimates due to temporal and spatial variations of the turbulent parameters (angle brackets denote average over the radar range resolution of 1 km). The high-resolution thermosonde observations allow us to test the applicability of the turbulent volume fraction model to the estimation of (e) from (C(2)(n)). The data indicate that the turbulent volume fraction should not be modeled as the fraction of unstable layers with gradient Richardson number R1

Book Synopsis Measurement Methods in Atmospheric Sciences by : Stefan Emeis
Download or read book Measurement Methods in Atmospheric Sciences written by Stefan Emeis and published by . This book was released on 2010 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Measurement Methods in Atmospheric Sciences provides a comprehensive overview of in-situ and remote sensing measurement techniques for probing the Earth's atmosphere. The methods presented in this book span the entire range from classical meteorology via atmospheric chemistry and micrometeorological fiux determination to Earth observation from space. Standard instruments for meteorological and air quality monitoring methods, as well as specialized instrumentation predominantly used in scientific experiments, are covered. The presented techniques run from simple mechanical sensors to highly sophisticated electronic devices. Special emphasis is on the rapidly evolving field of remote sensing techniques. Here, active ground-based remote sending techniques such as SODAR and LIDAR find a detailed coverage. The book conveys the basic principles of the various observational and monitoring methods, enabling the user to identify the most appropriate method. An introductory chapter covers general principles (e. g. inversion of measured data, available platforms, statistical properties of data, data acquisition). Later chapters each treat methods for measuring a specific property (e.g. humidity, wind speed, wind direction). Long chapters provide an introductory tabular list of the methods treated. More than 100 figures and 400 references, mostly to the recent scientific literature, aid the reader in reading up on the details of the various methods at hand. Recommendations at the end of each major chapter provide additional hints on the use of some instruments in order to facilitate the selection of the proper instrument for a successful measurement. A large number of national and international standards, providing precise guidelines for measuring and acquiring reliable, reproducible and comparable data sets are listed in the appendix. A dedicated index allows easy access to this valuable information. The book addresses undergraduate and graduate students in meteorological and atmospheric sciences, physical geography, ecology, environmental sciences, agriculture and related disciplines as well as scientists in the process of planning atmospheric measurements in field campaigns or working with data already acquired. Practitioners in environmental agencies and similar institutions will benefit from instrument descriptions and the extended lists in the appendix.' (Publisher)

Download or read book Radar Meteorology written by S. Raghavan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we all know, weather radar came into existence during the Second World War when aircraft detection radars had their vision limited by echoes from rain bearing clouds. What was often considered to be of nuisance value by the air force personnel trying to locate enemy aircraft was seen as an opportunity by the weather men. Thus adversity in one field was converted into an opportunity in another. Since then weather radar has found myriad applications with the increased sophistication of technology and processing systems. It has now become an indispensable tool for the operational forecasters, cloud physicists and atmospheric scientists. The current generation radar is but a distant echo of the radars of the 1940s. As a result, its operation and maintenance have become very complex, like the technology it uses. Therefore, there is a definite requirement of focussing our special attention not only on the science of radar meteorology but also on its operational aspects. The present book, as pointed out by the author, attempts to fill this gap. The author has presented the subject with a balanced blend of science, technology and practice. The canvas is indeed very broad. Starting with the history of weather radar development the book goes on to discuss in a lucid style the physics of the atmosphere related to radar observation, radar technology, echo interpretation, different applications and finally attempts to look into the future to indicate potential new opportunities in this field.
Book Synopsis Airborne Measurements for Environmental Research by : Manfred Wendisch
Download or read book Airborne Measurements for Environmental Research written by Manfred Wendisch and published by John Wiley & Sons. This book was released on 2013-03-22 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first comprehensive review of airborne measurement principles covers all atmospheric components and surface parameters. It describes the common techniques to characterize aerosol particles and cloud/precipitation elements, while also explaining radiation quantities and pertinent hyperspectral and active remote sensing measurement techniques along the way. As a result, the major principles of operation are introduced and exemplified using specific instruments, treating both classic and emerging measurement techniques. The two editors head an international community of eminent scientists, all of them accepted and experienced specialists in their field, who help readers to understand specific problems related to airborne research, such as immanent uncertainties and limitations. They also provide guidance on the suitability of instruments to measure certain parameters and to select the correct type of device. While primarily intended for climate, geophysical and atmospheric researchers, its relevance to solar system objects makes this work equally appealing to astronomers studying atmospheres of solar system bodies with telescopes and space probes.
