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.

Yazar hakkında
I graduated from the Physical Department of the Belarusian State University in Minsk, Belarus (1983). Since then I have worked for the last 22 years in the Laboratory of light scattering media optics at the Institute of Physics (Minsk, Belarus). At the moment I am working with the SCIAMACHY algorithm development team at the Institute of Environmental Physics in Bremen (Germany). The main task is the development of new cloud retrieval algorithms for water and ice clouds as seen by the spectrometer SCIAMACHY (in space from 2002). Main results are obtained in the field of geometrical optics, asymptotic radiative transfer theory and trace gases/aerosol/cloud properties retrievals using passive remote sensing techniques.
I have written three books: Light Scattering Media Optics (1999, 2001, 2004), Polarization Optics of Random Media (2003), and
