Paper Abstract

A method is proposed to estimate the accuracy of parameters retrieval from the spectral sea reflectance based on certain assumptions about errors distribution in the input data. Maximum likelihood method has been used to estimate the error of the retrieval stemmed from the random errors of experimental data. The method has been applied to the retrieval of chlorophyll-a concentration, coefficient of scattering in the backward direction of non-chlorophylous particles and absorption of yellow substance in the waters of north-east part of the Black sea. The retrieved chlorophyll concentrations are consistent with in situ measurements. The modeled values of scattering coefficient check well with measurements of extinction coefficient. Proposed accuracy estimates proved to be close to direct ones. The proposed method is general enough to be applicable to the accuracy estimation in various inverse problems of remote sensing of the ocean and atmosphere.
