Biography & Research Interest
Welcome Dr. Alexander Kokhanovsky to Join the Editorial Board of American Journal of Geographical Research and Reviews.
Alexander Kokhanovsky graduated in 1983 in Theoretical Physics (The Department of Physics, Belarussian State University, Minsk, Belarus) : the main topics of his thesis was the solution of the vector radiative transfer equation for the case of chiral light scattering media. A particular attention has been given to the study of the properties of radiation in deep layers of a turbid medium under study. The phase and extinction matrices have been calculated using the Maxwell theory for chiral
In 1983 Dr. Kokhanovsky has joined the Laboratory of Light Scattering Media of the Institute of Physics of National Academy of Sciences of Belarus as a Junior Research Scientist. In 1986 he started a Ph. D. course in Optics at the Institute of Physics (National Academy of Sciences of Belarus, Minsk, Belarus). During the Ph. D. his focus rapidly moved to studies of Atmospheric Optics, in particular to investigation of atmospheric aerosol and clouds using optical methods. As a Ph. D. student he was responsible for the several projects related to studies of light propagation and image transfer through atmosphere and ocean. The optical properties of whitecaps have been studied as well.
In December 1991 he was awarded the Ph. D. degree in Optics with the thesis “Optical properties of atmospheric coarse-mode aerosol and foams”. Simple analytical equations have been proposed for radiative characteristics of coarse-mode aerosols, water clouds, and foams in terms of the parameters of microstructure such as size distribution, shape, internal structure and chemical composition of scatterers.
After the PhD defence Dr. Kokhanovsky has focused his research on the development of fast algorithms to retrieve cloud properties using satellite observations. He also studied several inverse problems of light scattering media optics including the diffuse-wave spectroscopy and laser diffraction spectrometry. In 1994 Dr. Kokhanovsky has been awarded the Science and Technology Agency of Japan Fellowship to work at the National Space Development Agency (NASDA) of Japan on cloud remote sensing. He has spent 1 year (1996) in Tokyo (Earth Observation Research Center) working in the group of Prof. Teruyuki Nakajima in the area of cloud and snow remote sensing using
spaceborne observations (GLI/ADEOS). Afterwards he has been awarded the Alexander von Humboldt Fellowship (Clausthal University, Clausthal-Zellerfeld, Germany, 1998) and Engineering and Physical Sciences Research Council Fellowship (Imperial College, London, UK, 1999), where he has developed novel techniques to derive properties (e.g., particle size distribution) of light scattering particles using small-angle and polarimetric optical measurements. Also the tensor radiative transfer equation has been derived. This equation has been proved to be useful in studies of light propagation in anisotropic media.
In March 2001 he joined the Institute of Environmental Physics (Bremen University, Bremen, Germany), where he has been responsible for the development of cloud, snow and aerosol retrieval algorithms for MERIS, AATSR, and SCIAMACHY on board ENVISAT. A number of papers related to the generation and analysis of L2 aerosol, snow, and cloud products have been published. Dr. Kokhanovsky has participated and took a lead in several ESA, DFG, BMBF, and ESF projects. Also he has published three books during this period of time.
In October 2013 Dr. Kokhanovsky has got a permanent job at VITROCISET (Darmstadt, Germany) and has been appointed to carry work at EUMETSAT on the development of L2 aerosol and cloud retrieval algorithms for the Multi-viewing Multi-Channel and Multi – polarization Imager (3MI) on board Eumetsat Polar System – Second Generation (EPS-SG). The correspondent algorithms and ATBDs have been developed, validated and delivered to EUMETSAT.
