Use of satellite data by the Copernicus program for assessment of modeled wind field from atmospheric weather prediction models for the Black Sea

The issue of marine forecasts in NIMH is carried out by the numerical wind- wave forecast system for the Black Sea, which was developed and improved through the years.The existing operational marine forecasting system is based on state of art numerical spectral wave models SWAN and WAVEWATCH III (WW3), providing 72-hours wind wave forecast for the Black Sea area. The input data for the system are the wind fields at 10 m over the sea surface provided by the atmospheric model ALADIN, specially set up for the Black Sea. The accuracy of the wind - wave forecast depends largely on the quality of the wind fields and the type of atmospheric models - global or regional. This paper present the results of the evaluation of the wind speed at 10 m from the regional atmospheric model ALADIN and HRES – a global atmospheric model with high spatial resolution of the European Center for Medium-Range Weather Forecast (ECMWF). The statistical assessment was made by comparing of modeled wind speed fields with satellites wind data (in near real time) at 10 m from ASCAT scatterometers of satelltes MetOP B and MetOP C over the Black Sea, which are disseminated by the Copernicus Marine Environment Monitoring Service (CMEMS), part of the Copernicus Program. The statistical results show a good agreement between the models and satellite measurements
