Assimilation of satellite data in numerical models of the black sea coastal region - problems and approaches to the improvement of technology
The article presents an analysis of the results of comparison the data of numerical simulation of hydrodynamics of the coastal northeastern region of the Black Sea, carried out as part of operational oceanography, with contact and satellite observations. It is shown that the correction of model calculations of salinity according to satellite altimetry data in shallow areas of the sea is incorrect. The features of the applied assimilation technology are considered and methods for improving it are proposed based on the use of the ideology of the Kalman filter, which assumes tracking the evolution of the correlation function of modeling errors.
