Clouds affect the climate of the Earth, and they are an important factor in the weather. Therefore, their radiative properties must be understood in great detail. This book summarizes current knowledge on cloud optical properties, for example their ability to absorb, transmit, and reflect light, which depends on the clouds’ geometrical and microphysical characteristics such as sizes of droplets and crystals, their shapes, and structures. In addition, problems related to the image transfer through clouds and cloud remote sensing are addressed in this book in great detail.This book can be an important source of information on theoretical cloud optics for cloud physicists, meteorologists and optical engineers. All basic ideas of optics as related to scattering of light in clouds (e.g. Mie theory and radiative transfer) are considered in a self consistent way. Consequently, the book can also be a useful textbook to newcomers to the field.

The theory of the scattering of light by small particles is very important in a wide range of applications in atmospheric physics and atmospheric optics, ocean optics, remote sensing, astronomy and astrophysics and biological optics. This book summarises current knowledge of the optical properties of single small particles and natural light scattering media such as snow, clouds, foam aerosols etc. The book considers both single and multiple light scattering regimes, together with light scattering and radiative transfer in close-packed media. The third edition incorporates new findings in the area of light scattering media optics in an updated version of the text.

Springer/Praxis have a successful mini program of books on various aspects of light scattering, and now have a journal "Light Scattering Review" under consideration proposed by Alex Kokhanovsky. The atmospheric air contains not only gases but also various types of airborne particles (known as aerosols) ranging from dust grains to microbes. These small particles influence atmospheric visibility, the thermodynamics of the atmosphere, and they are also of great importance in any consideration of climate change problems. Aerosols may also be responsible for the loss of harvest, health problems among humans and ecological disasters. Therefore, it is of great importance to study aerosol properties on a global scale. Such studies ultimately should be based on global observations using instruments positioned on the space platforms.

This book provides an account of recent developments in light scattering media optics. Leading researchers focus on both the theoretical and experimental results in the area. In particular, light scattering by ice crystals, soil particles and biological particles is considered. This volume first discusses single light scattering, followed by multiple light scattering and finally examines possible applications in combustion and marine research.

Lightscatteringisusedinmanyapplications,rangingfromopticalparticlesizing of powders to interstellar dust studies. At the moment there is no a specialized journal aimed at studies of exclusively light scattering problems. Instead, d- ferent aspects of the problem and also di?erent applications are considered in a varietyof specializedjournalscoveringseveralscienti?cdisciplinessuchasch- istry, physics, biology, medicine, astrophysics, and atmospheric science, to name afew. The Light Scattering Reviews (LSR) series started in 2006 with the aim of facilitating interaction between di?erent groups of scientists working in diverse scienti?c areas but using the same technique, namely light scattering, for so- tion of speci?c scienti?c tasks. This second volume of LSR is devoted mostly to applications of light scattering in atmospheric research. The book consists of eight contributions prepared by internationally recognized authorities in cor- spondent research ?elds. The ?rst paper prepared by Howard Barker deals with the recent devel- ments in solar radiative transfer in the terrestrial atmosphere and global climate modelling.In particular, methods to compute radiative transfer characteristics needed for numerical global climate models are discussed in a great depth. Their de?cienciesareaddressedaswell.Theproblemof3Dradiativetransferincloudy atmospheres, a hot topic in modern climate modelling, is also considered.

This volume of Light Scattering Reviews describes some recent advances in a broad area of light scattering media optics. It is composed of three parts. The ?rst part is concerned with single light scattering by small nonspherical p- ticles such as crystals in clouds or suspensions of various cells. Most natural media are characterized by a variety of shapes and often a particular selection of particle shape is not representative of the ensemble of shapes encountered during measurements. This being the case, theoretical calculations are only of limited value and comprehensive experimental studies must be performed to e- cidate the question of optical response for a collection of particles having diverse shapes. The volume opens with the paper of Timothy Garrett, which describes a number of recent in situ airborne experiments related to the quanti?cation of optical properties of cirrus clouds. Min Xu and Alvin Katz discuss a novel statistical approach to deal with the light extinction and absorption properties of small nonspherical particles having a refractive index close to that of the host medium. In this case, van de Hulst’s anomalous di?raction theory can be used. The new approach is applied to studies of bio-agent detection and monitoring. Michael Kahnert presents a comprehensive theoretical treatment of symmetries in linear boundary value problems. The use of symmetries simpli?es electrom- netic scattering problems to a great extent.

The book discusses the current status of the retrieval of aerosol properties from satellite radiometer measurements of the spectral top-of-atmosphere reflectances. The results described in the book are summarized in Chapter 1 (Introduction). Chapters 2 and 3 describe the aerosol retrievals based on NASA MODerate-resolution Imaging Spectroradiometer (MODIS) data. In particular, Chapter 2 is concerned with the description of the dark-land official MODIS Collection 5 aerosol retrieval algorithm. Chapter 3 uses the time series technique to improve MODIS aerosol retrievals over land.The main subject of Chapter 4 is the introduction of the iterative algorithm to get the aerosol optical thickness (AOD) and surface reflectance from ESA MEdium Resolution Imaging Spectrometer (MERIS) data. The algorithm is based on the iterative solution of the radiative transfer equation. Chapters 5, 6, and 7 describe different AOD retrieval algorithm approaches using the (Advanced) Along Track Scanning Radiometer (ATSR-2 and AATSR) data.In Chapter 8 an aerosol retrieval algorithm based on the synergy of AATSR and Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY (SCIAMACHY) data is introduced.The retrievals of AOD from the Multiangle Imaging SpectroRadiometer (MISR) instrument on board the NASA TERRA satellite are described in Chapter 9. Polarimetric remote sensing of aerosol properties using airborne and satellite measurements is the subject of Chapter 10. The results described in Chapters 2 - 10 are obtained using polar satellites. Chapter 11 addresses observations from a geostationary orbit using as an example the data from the Spinning Enhanced Visible and Infrared Imager on the Meteosat Second Generation. The final Chapter is aimed at the synthesis of all available AOD products to better understand the global spatial distribution of terrestrial aerosols including sea salt, desert dust, smoke, etc.

This fourth volume of Light Scattering Reviews is composed of three parts. The ?rstpartisconcernedwiththeoreticalandexperimentalstudiesofsinglelightsc- tering by small nonspherical particles. Light scattering by small particles such as, for instance, droplets in the terrestrial clouds is a well understood area of physical optics. On the other hand, exact theoretical calculations of light scattering p- terns for most of nonspherical and irregularly shaped particles can be performed only for the restricted values of the size parameter, which is proportional to the ratio of the characteristic size of the particle to the wavelength?. For the large nonspherical particles, approximations are used (e. g. , ray optics). The exact th- retical techniques such as the T-matrix method cannot be used for extremely large particles, such as those in ice clouds, because then the size parameter in the v- iblex=2?a/???,wherea is the characteristic size (radius for spheres), and the associated numerical codes become unstable and produce wrong answers. Yet another problem is due to the fact that particles in many turbid media (e. g. , dust clouds) cannot be characterized by a single shape. Often, refractive indices also vary. Because of problems with theoretical calculations, experimental (i. e. , la- ratory) investigations are important for the characterization and understanding of the optical properties of such types of particles. The ?rst paper in this volume, written by B. Gustafson, is aimed at the descr- tionofscaledanalogueexperimentsinelectromagneticscattering.

Light scattering by densely packed inhomogeneous media is a particularly ch- lenging optics problem. In most cases, only approximate methods are used for the calculations. However, in the case where only a small number of macroscopic sc- tering particles are in contact (clusters or aggregates) it is possible to obtain exact results solving Maxwell’s equations. Simulations are possible, however, only for a relativelysmallnumberofparticles,especiallyiftheirsizesarelargerthanthewa- length of incident light. The ?rst review chapter in PartI of this volume, prepared by Yasuhiko Okada, presents modern numerical techniques used for the simulation of optical characteristics of densely packed groups of spherical particles. In this case, Mie theory cannot provide accurate results because particles are located in the near ?eld of each other and strongly interact. As a matter of fact, Maxwell’s equations must be solved not for each particle separately but for the ensemble as a whole in this case. The author describes techniques for the generation of shapes of aggregates. The orientation averaging is performed by a numerical integration with respect to Euler angles. The numerical aspects of various techniques such as the T-matrix method, discrete dipole approximation, the ?nite di?erence time domain method, e?ective medium theory, and generalized multi-particle Mie so- tion are presented. Recent advances in numerical techniques such as the grouping and adding method and also numerical orientation averaging using a Monte Carlo method are discussed in great depth.
