Paper Abstract

An experimental study of statistical characteristics of fluorescent lidar echo signals and spatial distribution of optically active components in waters of the Gorky reservoir at 40 x 10 km experimental area covering the floodplain, channel and estuaries of inflowing rivers was performed. The measurements were carried out during 4 days from 1 August to 4 August 2017 and from 20 September to 22 September 2018 at the stations and continuously along the motorboat track with the help of fluorescent lidar UFL-9 which allows to restore concentrations of chlorophyll a, colored organic matter and total suspended matter in the upper water layer with thickness of about 0.2 to 1.0 m for eutrophic waters. This paper presents maps of their spatial distribution, demonstrating different scales of inhomogeneities, average values and spatial variability of chlorophyll a, total organic carbon and total suspended matter as well as data on variance and spatial spectrum of fluctuations of the elastic backscattering signal. Regressions between mean values and coefficients of variation of suspension and chlorophyll a, and between coefficients of variation of suspension and energy of the elastic backscattering signal are established.
