Operational monitoring system is developed to automatize the process of diagnosis and forecast of hydrological fields of marine environment in the Sevastopol Black Sea region based on the local hydrodynamical model POM. The initial and boundary conditions for the local model are set from the basin model of the Black Sea dynamics. The data obtained by SKIRON Regional Forecast Center of Athens University is applied as the atmospheric effect. For the parameterization of vertical mixing in local circulation model POM turbulence model based on turbulence hypotheses of Rott -Kolmogorov and generalized by Mellor and Yamada in the case of a stratified flow is included. The model takes into consideration the penetration of the short-wave solar radiation into the water column. System automation is implemented using the CalcMan software package which is an own development of Marine Hydrophysical Institute. The output fields are accessible in the NetCDF format with horizontal spatial resolution constituting 1 km, vertical resolution -18 irregular levels from 2.5 to 1000 m and time resolution -3 hr. The system provides a possibility of daily updating the forecast data. Based on the THREDDS server, the specialized visualization subsystem is installed and configured to visualize and disseminate simulations results. Its user-friendly interface allows a server-side analysis of all the forecasted fields, permits to construct horizontal and vertical sections, vertical profiles and time series, to create animated pictures without downloading the data to a client's side. OPENDAP and NetcdfSubset interfaces are used for disseminating data in a digital form.

Problems of reliability control of the atmospheric forcing data used for setting boundary conditions in the model simulations performed in the Black Sea marine forecasting center (BS MFC) of MHI (RAS) are considered. To set the boundary conditions on the sea surface it is necessary to have information about the heat, momentum, evaporation and precipitation total fluxes and short-wave radiation penetrating in the upper sea layer with a thickness of about fifty meters. To check the reliability of the data obtained the information not only about these fluxes, but also about their components appears to be of high value. The first section describes the weather forecasts applied in BS MFC for the atmospheric boundary layer. The methods for controlling the weather forecast reliability of the atmosphere boundary layer are considered. The software developed to solve this task is briefly described in the second section. The first group of control methods is based on the calculation according to the approximate formulas short-wave and long-wave radiation fluxes. For other components of total fluxes their comparison according to the forecast data of two atmospheric models used in BSMFC to set the boundary conditions on the sea surface is used. The third section contains the examples of the errors occurring in preparing the weather forecast data. Errors in the data on the magnitude of the albedo and upward short-wave radiation fluxes were discovered on the basis of the application of the developed methods. The conclusions drawn from the results obtained testify to effectiveness of the system developed to control data reliability. Further investigations are planned. It is noted that the results represented in the paper constitutes a basis for development of the software intended to correct the revealed errors.Keywords: marine forecasts, atmospheric forcing, boundary conditions, heat flows, evaporation, precipitation, long-wave radiation, short-wave radiation, albedo, Stefan -Boltzmann constant, reliability. Currently, the center continues to operate independently. One of the tasks of further improvement of the operating system of the Black Sea marine forecasting center (BSMFC) is associated with the creation of quality control and reliability of the atmosphere boundary layer condition (atmospheric forcing) data. This data is used to specify the boundary conditions at the sea surface performing diagnostic and prognostic calculations by means of the Black Sea circulation model.The purpose of this paper is to describe the principles and methods assumed as a basis of the quality control module being developed, as well as brief information on the developed version of the software and an illustration of reliability of the atmospheric forcing data testing results obtained by MHI BS MFC. This data comes from two sources:-SKIRON Meteorological Center (Greece) [1]; -System of regional weather forecasts of MHI Ocean-Atmosphere Interaction (OAI) department [2].
