Thorsen and published by . This book was released on 2014 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical cirrus cloud properties from elastic backscatter lidars--- namely the Atmospheric Radiation Measurement (ARM) program's ground-based micropulse lidars (MPL) and the spaceborne Cloud-Aerosol Lidar Infrared Pathfinder Satellite Observations (CALIPSO) lidar--- are examined. The MPL detects significantly less cirrus clouds relative to CALIPSO, particularly during the daytime. However, the MPL samples enough cirrus at night to provide similar statistics of macrophysical and optical properties as CALIPSO. Both sets of lidar observations are supplemented with cloud radar observations to calculate radiative heating rate profiles from a ground-based and spaceborne perspective. The inferred radiative effect of clouds is much smaller when using the ground-based data, mostly due to the lack of cirrus detected by the MPL. The relatively new and more advance ARM Raman lidar (RL) is shown to be more sensitive to cirrus than the ARM MPL and detects a similar amount of cirrus as CALIPSO. Daytime measurements using the RL elastic channel are relatively unaffected by the solar background and are therefore suited for checking the observed diurnal cycles from the MPL and CALIPSO. Comparisons with RL observations show that the geometrical thickness of cirrus from the MPL and CALIPSO datasets are biased thin during the daytime due to increased noise. Various upgrades since its conception have made the ARM RL a viable tool for cloud studies as demonstrated by this thesis. Since the ARM RL was not originally designed for cloud observations, the current automated processing algorithms do not identify all clouds nor attempt to retrieve cloud extinction profiles. Therefore an improved Feature detection and EXtinction retrieval (FEX) algorithm is developed. The approach of FEX is to use multiple quantities to identify features (clouds and aerosols) using range-dependent context-sensitive detection thresholds. The use of multiple quantities provides complementary depictions of cloud and aerosol locations. The extinction profiles are directly retrieved using the Raman method, which are supplemented by other retrieval methods developed for elastic backscatter lidars. A classification of feature type is made guided by the atmosphere's thermodynamic state and the feature's scattering properties. The contribution of multiple scattering, which is significant for hydrometeors, is explicitly considered for each of the ARM RL channels. The FEX framework is also suitable for other advance lidars, i.e. high spectral resolution lidars (HSRL). The continuously operated, automated ARM RLs paired with FEX provide an enormous wealth of water vapor, temperature, aerosol and cloud data unmatched by other remote sensing systems.

This book was released on 2018-08-16 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 8 to 13 micron spectral region is an important atmospheric window for radiometric studies of the Earth's surface and clouds. Most of the Earth-atmosphere longwave radiative loss to space occurs in this spectral region. Selective gaseous absorption in this window occurs in the 9.6 micron ozone band with the remaining absorption dominated by the water vapor continuum. Cirrus clouds have a large impact on the transmittance of this atmospheric window region; it is therefore important to understand the interaction of cirrus cloud with the radiation field for climate studies and in the interpretation of satellite radiometric measurements. The focus was to employ observations of the High-resolution Interferometer Sounder (HIS) made during First ISCCP Regional Experiment (FIRE) to improve the understanding of the radiative properties of cirrus clouds within this window region. Studies were undertaken to investigate the coupling between the microphysical properties of cirrus clouds and their spectral variation within this window region. Extensions of the HIS studies to satellite measurements, with regards to remote sensing and interpretation, were also investigated. Smith, William L. and Ackerman, Steven A.

Download or read book Cirrus written by David K. Lynch and published by Oxford University Press. This book was released on 2002-01-24 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cirrus clouds are high, thin, tropospheric clouds composed predominately of ice. In the last ten years, considerable work has shown that cirrus is widespread--more common than previously believed--and has a significant impact on climate and global change. As the next generation weather satellites are being designed, the impact of cirrus on remote sensing and the global energy budget must be recognized and accommodated. This book, the first to be devoted entirely to cirrus clouds, captures the state of knowledge of cirrus and serves as a practical handbook as well. Each chapter is based on an invited review talk presented at Cirrus, a meeting hosted by the Optical Society of America and co-sponsored by the American Geophysical Union and the American Meteorological Society. All aspects of cirrus clouds are covered, an approach that reaches into diverse fields. Topics include: the definition of cirrus, cirrus climatologies, nucleation, evolution and dissipation, mixed-phase thermodynamics, crystallinity, orientation mechanisms, dynamics, scattering, radiative transfer, in situ sampling, processes that produce or influence cirrus (and vice versa), contrails, and the influence of cirrus on climate.

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.
