<abstract>
<p>The paper presents the development of the Black Sea community nowcasting and
forecasting system under the Black Sea GOOS initiative and the EU framework
projects ARENA, ASCABOS and ECOOP. One of the objectives of the Black Sea
Global Ocean Observing System project is a promotion of the nowcasting and
forecasting system of the Black Sea, in order to implement the operational
oceanography in the Black Sea region. The first phase in the realization of
this goal was the development of the pilot nowcasting and forecasting system
of the Black Sea circulation in the framework of project ARENA funded by the
EU. The ARENA project included the implementation of advanced modeling and
data assimilation tools for near real time prediction. Further progress in
development of the Black Sea nowcasting and forecasting system was made in
the frame of ASCABOS project, which was targeted at strengthening the
communication system, ensuring flexible and operative infrastructure for
data and information exchange between the Black Sea partners and end-users.
The improvement of the system was made in the framework of the ECOOP
project. As a result it was transformed into a real-time mode operational
nowcasting and forecasting system. The paper provides the general
description of the main parts of the system: circulation and ecosystem
models, data assimilation approaches, the system architecture as well as
their qualitative and quantitative calibrations.</p>
