Book Description
Introduces the physical processes and meteorology required to understand the behaviour of light and radiation in the atmosphere. Integrating the treatment of atmospheric optics from the ultraviolet to the microwave, the book presents a detailed overview, together with discussions, on the associated meteorology and atmospheric composition, which gives the meteorological background necessary to deal with the varying conditions found in the real atmosphere. Mathematical details provide a concise description of results thus allowing readers with a knowledge of meteorology or a single wavelength region to comprehend the transmission, emission and scattering in all wavelength regions. Rayleigh and Mie scattering are covered as well as the aerosol and raindrop distributions found in the atmosphere. Detailed models of the atmosphere and the distribution of trace gases are supplied, and finally a chapter is devoted to standardised software and available data bases.

Book Description
Measurements are presented of the microwave radiation from Jupiter in the wavelength range 0.8 - 1.5 cm. Wideband observations indicate a broad absorption feature caused by the pressure broadened microwave spectrum of the ammonia present in Jupiter's atmosphere. Spectral line observations show emission features which are interpreted as indicating the presence of a temperature inversion high in the Jovian atmosphere. The measurements are compared with theoretical spectra computed from variations of previously proposed model atmospheres for Jupiter. A new radio telescope was used for the observations and its precise calibration is also described. (Author).

Book Description
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.

Book Description
Microwave radiation is absorbed by atmospheric oxygen and water vapor and is absorbed and scattered by rainfall. The report provides values of these losses in the frequency decade from 10 to 100 GHz for paths through the atmosphere at elevation angles from 0 to 90 degrees. The theoretical expressions for oxygen absorption are assembled in explicit form. The resonant frequencies are taken from published low-pressure measurements, and the entire absorption profile is fitted to published intermediate and atmospheric pressure results, with a constant of proportionality and the absorption resonance line width used as fitting parameters. The absorption line breadth is found to deviate from the accepted linear pressure dependence, increasing approximately as the square root of pressure for pressures above one-half atmospheric. The results of similar analyses of water vapor absorption are assembled and combined with the results of oxygen absorption analyses to obtain the complete absorption coefficients as a function of the atmospheric parameters. The total attenuation due to absorption in the clear atmosphere is computed for a model atmosphere with various water vapor concentrations. Results are provided in graphical form, giving attenuation as a function of frequency and elevation angle. Rough estimates for rain attenuation are made for crude model storms which occur for 1, 0.1, and 0.01 percent of the time. Total values of the attenuation for the model storms and the atmospheric absorption are provided.

Book Description
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.
