The relation of water transparency with the content of suspensions and solutes of organic and inorganic genesis allows us to regard transparency as one of the most important physical parameters of water quality. The purpose of this study was to evaluate the characteristics of spatial and temporal distribution of water transparency of the surface layer of Lake Baikal using satellite remote sensing data. Remote sensing is an indispensable tool in the study of large inland water bodies including Lake Baikal with water area of 31.7 thousand sq. km. Regional techniques for determining relative water transparency of the surface layer of Lake Baikal with AVHRR data were developed by comparing arrays of ship and satellite data. A series of maps of water transparency of the surface layer of Lake Baikal for the period from June to October of different years was compiled using these regional algorithms. The variation of average transparency of surface layer water in some areas of the lake and throughout the whole water area was studied. Also, the main features of spatial and temporal distribution of water transparency of the surface layer of Lake Baikal during ice-free period were described.
Keywords: Lake Baikal, relative water transparency, AVHRR data, spatial and temporal distribution, regional technique
