This book was released on 2019-05-24 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue “Atmospheric Conditions for Wind Energy Applications” hosts papers on aspects of remote sensing for atmospheric conditions for wind energy applications. Wind lidar technology is presented from a theoretical view on the coherent focused Doppler lidar principles. Furthermore, wind lidar for applied use for wind turbine control, wind farm wake, and gust characterizations is presented, as well as methods to reduce uncertainty when using lidar in complex terrain. Wind lidar observations are used to validate numerical model results. Wind Doppler lidar mounted on aircraft used for observing winds in hurricane conditions and Doppler radar on the ground used for very short-term wind forecasting are presented. For the offshore environment, floating lidar data processing is presented as well as an experiment with wind-profiling lidar on a ferry for model validation. Assessments of wind resources in the coastal zone using wind-profiling lidar and global wind maps using satellite data are presented.

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 Real Time Remote Measurement of Wind Speed by Laser Back Scattered Single Particle Correlation Techniques written by Chiao-Yao She and published by . This book was released on 1977 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possibility of conducting remote wind measurements in real time using only cw laser equipment located on the ground at a given point is very attractive and may offer wide-spread applications in atmospheric research and operations. This research program therefore investigated laser techniques for remote sensing of atmospheric flow. It emphasized the development of methods for single-ended remote wind speed measurement. These methods provide high spatial resolution and potentially long range with low laser power and minimum measurement time. Realistic performance criteria was formulated in order to understand the potential of a given technique and field wind measurements were performed to evaluate its feasibility and usefulness. The existing laser Doppler velocimeter was investigated in this way, and it was found to be out-performed, under practical conditions, by a new laser time-of-flight velocimeter discovered during the course of this program.

Download or read book Atmospheric Acoustic Remote Sensing written by Stuart Bradley and published by CRC Press. This book was released on 2007-12-26 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sonic Detection and Ranging (SODAR) systems and Radio Acoustic Sounding Systems (RASS) use sound waves to determine wind speed, wind direction, and turbulent character of the atmosphere. They are increasingly used for environmental and scientific applications such as analyzing ground-level pollution dispersion and monitoring conditions affecting wind energy generation. However, until now there have been no reliable references on SODAR and RASS for practitioners in the field as well as non-experts who wish to understand and implement this technology to their own applications. Authored by an internationally known expert in the design and use of SODAR/RASS technology, Atmospheric Acoustic Remote Sensing: Principles and Applications systematically explains the underlying science, principles, and operational aspects of acoustic radars. Abundant diagrams and figures, including eight pages of full-color images, enhance clear guidelines and tools for handling calibration, error, equipment, hardware, sampling, and data analysis. The final chapter explores applications in environmental research, boundary layer research, wind power and loading, complex terrain, and sound speed profiles. Atmospheric Acoustic Remote Sensing offers SODAR and RASS users as well as general remote sensing practitioners, environmental scientists, and engineers a straightforward guide for using SODARs to perform wind measurements and data analysis for scientific, environmental, or alternative monitoring applications.

Available in PDF, EPUB and Kindle. Book excerpt: The development of selected techniques for the remote measurement of winds, shear, turbulence, aerosols, and temperature and moisture profiles has been outlined in some detail. Emphasis has been placed on techniques that may provide high-resolution data in the vicinity of airbases. A representative and fairly extensive list of references to the evolution of the various techniques has been prepared. The FM-CW radar and CO2 pulse Doppler laser have been identified as valuable for low-level wind and shear measurements. Strong downdraft conditions may be identified through use of infrared thermal anomaly detectors. Temperature and moisture profiles may be obtained through a combination of active sounding for profile inflection points and thermal or microwave multichannel radiometry.
