This book was released on 1970 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: For quite sometime oceanographers and meteorologists have been attempting to describe dynamic ocean features as a function of various meteorological parameters. Data used in past studies have been limited by location, instrumentation, and processing. Only recently have remote sensing techniques been applied to determining dynamic ocean features. The results of recent passive and active microwave experiments are presented in the papers contained in this report. Passive microwave (radiometric) observations appear to show that this technique may be capable of determining surface roughness conditions (sea state, spray, percentage of foam and whitecaps, etc.). Active microwave (radar) results appear to show a non-linear relationship of the backscatter cross section as a function of windspeed. Radar data is also being used to describe more fully the high frequency component of the ocean wave spectrum. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Passive Microwave Remote Sensing of Oceans Igor V. Cherny and Victor Yu. Raizer In Passive Microwave Remote Sensing of Oceans, the detailed results of more than 20 years of experimental and theoretical investigations in the field of ocean remote sensing, utilising microwave radiometric techniques and multi-frequency aerospace instruments, are presented. Experimental results presented in this book to some extent contradict the traditional view that microwave radiometry and, in particular, millimetre-wave frequencies are not useful for remote sensing of oceans. The authors show that studies of the ocean and atmosphere as a coupled system, and of processes occurring at the ocean surface and in deep water, can be reliably evolved using compact passive radiometric sensors. They further demonstrate that for studies of global, large-scale and local processes in the ocean-atmosphere system, only the combination of microwave and optical techniques will reveal the spatial structure and dynamics of the ocean surface at scales from centimetres to several hundred metres. The text first introduces ocean surface phenomena, discussing the ocean-atmosphere interface, the classification of surface waves, the generation and statistics of wind waves, and wave-breaking and foaming processes. The microwave emission characteristics of the ocean surface are then described, and the influence of wind waves, bubble-foam-spray coverage, oil spills and sea ice are discussed. The instruments and methods used for passive microwave remote sensing of the oceans from both aircraft and from satellites are reviewed. Microwave observations of processes in the ocean-atmosphere system are then described in detail, incorporating a new approach for microwave diagnostics of deep-ocean processes. Examples presented include the Rossby soliton, frontal zone in the Kurosio region, influence of brief showers on the subsurface layer, and interaction of tropical cyclones with the ocean during their origin and subsequent trajectories over the ocean surface. Readership: Undergraduate and postgraduate students studying remote sensing, marine science, oceanography, geography, geophysics, meteorology, climatology, atmospheric physics and environmental science. Professional oceanographers and those interested in oceanographic remote sensing processes and their applications, marine scientists and engineers, environmental scientists, and those studying the ocean-atmosphere system.

Download or read book Microwave Radiation of the Ocean-Atmosphere written by Alexander G. Grankov and published by Springer. This book was released on 2015-12-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes different approaches to the analysis of heat and dynamic processes in the ocean-atmospheric interface with satellite passive radiometric observations at microwaves. It examines the feasibility of determining synoptic, seasonal and year-to-year variations of sensible, latent and momentum fluxes to a useful accuracy using the DMSP SSM/I and EOS Aqua AMSR-E data directly from the measured brightness temperatures. An important object in the studies is the North Atlantic with emphasize on the areas with high midlatitude cyclon activity: here the main results have been obtained by combining data from the vessel experiments NEWFOUEX-88, ATLANTEX-90 and the data of microwave radiometers from the DMSP and EOS Aqua satellites. The role of vertical turbulent and horizontal advective heat transfer in forming interrelations between the brightness temperature of the system ocean-atmosphere and surface heat fluxes in the range of synoptic time scales is analyzed. Special sections of the book describe some results of analysis of reaction of the system ocean-atmosphere on passing of the tropical cyclone Katrina (August 2005) in the Florida Strait as well as a behavior of the system in the period of a time preceding to origination the cyclone Humberto (September 2007) in the Mexico Gulf. The long-term goal of this research is the search for effects and regularities, which can explain the reasons for the tropical cyclones appearance. Some characteristics of the tropical cyclones (brightness temperature and heat contrasts, etc.) are compared with those for midlatitude cyclones. At the same time as covering a key topic area with implications for global warming research, this text is also usefull to students who want to gain insight into application of satellite microwave radiometric methods for studying the air-sea interaction. Key themes: microwave radiometry, air-sea interaction, midlatitude and tropical cyclones, atmosphere boundary layer, heat and momentum surface fluxes.

This book was released on 2009-12-03 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: We will show in this monograph some possibilities of using the potential of satellite passive microwave radiometric methods for the analysis of variations of heat and dynamic processes in the ocean–atmosphere interface in a wide range of time scales – from mesometeorogical (hours, daily) to seasonal (month) and multiyear (climatic) ones. The most essential mechanisms of intercommunication of natural microwave radiation of the system ocean–atmosphere (SOA) with the vertical turbulence fluxes of sensible, latent heat, as well as the momentum at the boundary of the SOA are studied. We will consider the turbulence heat fluxes as the factors generated by the c- otic movements in the atmosphere, when every small individual part of air is moved irregularly. Here, one can observe a transfer of the energy from large-scale to sma- scales; the average distance between the air particles is increased with a time. Also, the potential of remote sensing the characteristics of heat and water adv- tion and their accumulation in the atmosphere boundary layer are demonstrated. In these studies, we mean mainly the middle and high latitudes of the North Atlantic, which are forming the weather conditions and climatic trends over Europe and European territories of the Russia.

Download or read book Ocean Surface Currents Reconstruction from Microwave Radiometers Measurements written by Cristina González Haro and published by . This book was released on 2017 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean currents are a key component to understanding many oceanic and climatic phenomena and knowledge of them is crucial for both navigation and operational applications. Therefore, a key problem in oceanography is the estimation of the synoptic velocity field. Currently, global ocean surface velocities are routinely estimated from Sea Surface Height (SSH) measurements provided by altimeters. However, the separation between passes, as well as and the limited number of available altimeters leads to errors in the accurate location of oceanic currents when these measurements are used exclusively. Contrarily, satellite images of Sea Surface Temperature (SST) provide a good qualitative view of the location of ocean patterns, which has encouraged the investigation of alternative methodologies to reconstruct the velocity field based on these observations. This Ph.D. thesis has assessed the capability of SST microwave radiometers observations to retrieve ocean surface currents. The reconstruction of the ocean surface currents from SST observations can be expressed in terms of a transfer function notation, that allows to convert SST maps into SSH, and thus into currents. Because under geostrophic balance, the slope of SSH is proportional to ocean surface currents. This transfer function can be theoretically derived using the Surface Quasi-Geostrophic equations (SQG). Two different approaches were analyzed at a global scale: on one side, the analysis of the validity of the SQG approach has been performed, and on the other, an approach based on the synergetic properties between simultaneous SST and SSH observations has been analyzed. Both approaches have been compared with ocean surface currents retrieved from merged altimetric observations. The study has been focused on the period from October 2002 to May 2005, since during that period there were available four different altimeters, and the quality of the merged altimetric observations was enhanced. The analysis of the validity of SQG at a global scale revealed that this dynamical model is valid near the major extratropic current system such us the Gulf Stream, the Antartic Circumpolar Current, Kuroshio currents. Besides, the potential of MW SST observations to reconstruct ocean surface currents was analyzed using a synergetic approach: the combination of the SST phase with the SSH spectra. Actually, we explored under which environmental conditions the phase of the MW SST is close to the SSH phase. Results showed that the phase of the MW SST can be used to retrieve ocean currents during winter, near the major extratropical current systems, which are characterized by an intense mesoscale activity and the presence of strong thermal gradients, and deep ML. Furthermore, the reconstruction of the velocity fields from an ideal transfer function built up from simultaneous SST and SSH observations revealed that the SQG approach can be enhanced. The spectral properties of this ideal transfer function derived from simultaneous SST and SSH observations were characterized at a global scale. The analysis of spectral properties of the transfer function between SST and SSH observations revealed that despite daily spectral can be flatter or steeper than the k̂{-1} predicted by SQG theory, in mean eSQG is a good statistically approach to retrieve ocean currents, when no simultaneous observations of SSH and SST are available.

This book was released on 2000-02 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a selection of refereed papers presented at the 6 Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment held in Florence, Italy on March 15-18, 1999. Over the last two decades, passive microwave remote sensing has made considerable progress, and has achieved significant results in the study of the Earth's surface and atmosphere. Many years of observations with ground-based and satellite-borne sensors have made an important contribution to improving our knowledge of many geophysical processes of the Earth's environment and of global changes. The evolution in microwave radiometers aboard satellites has increased steadily over recent years. At the same time, many investigations have been carried out both to improve the algorithms for the retrieval of geophysical parameters and to develop new technologies. The book is divided into four main sections: three of these are devoted to the observation of the Earth's surface and atmosphere, and the fourth, to future missions and new technologies. The first section deals with the study of sea and land surfaces, and reports recent advances in remote sensing of ocean wind, sea ice, soil moisture and vegetation biomass, including electromagnetic modelling and the assimilation of radiometric data in models of land surface processes. The following two sections are devoted to the measurement of atmospheric quantities which are of fundamental importance in climatology and meteorology, and, since they influence radio-wave propagation, they also impact on several other fields, including geodesy, navigational satellite and radioastronomy. The last section presents an overview of new technologies and plans for future missions.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the proceedings of the COSPAR/SCOR/ IUCRM Symposium "Oceanography From Space" held in May 1980 in Venice, Italy. COSPAR (The Committee for Space Research) suggested holding a joint symposium with SCOR (The Scientific Committee for Oceanic Research) as a major review of space oceanography. Since this meeting fitted well with a series of colloquia organized by the IUCRM (The Inter-Union Commission on Radio Meteorology), these three bodies joined in sponsoring the meeting. The conference was hald 16 years after the first discussions of possible spaceborne observations of the ocean at a meeting organized in 1964 in Woods Hole. Gifford'Ewing was then keen to see oceanography benefit from the new satellite technology being developed, and he begins this volume by noting that most of the suggestions put forward in 1964 have now, at last, been successfully demonstrated in practice. The papers that follow show the variety of measurement techniques available or possible, and many of the types of studies in which they can be used. Papers are arranged in a general section, and in 6 specialized sections each of which starts with a brief introduction summarizing important results.
