INTRODUCTIO" 
The Black Sea Monitoring and Forecasting Centre (BS- 
MFC) provides analysis, forecast and reanalysis for the 
5lue and green ocean state in the Black Sea basin. Since 
2016, BS-MFC is guaranteeing service standards, efficiency 
in operations and users support through its Local Service 
Desk and technical Interfaces PU-DU. The BS-MFC 
catalogue, includes 6 main products with a number of 72 
online datasets, operationally updated (Near Real Time 
ones are updated every day, while Multi Year ones are 
updated twice a year; from May 2021, they include interim- 
mode production performed every month). Additionally, 
BS-MFC implements scientific evolution program for 
product catalogue upgrades and for the next generation of 
forecasting and reanalvsis systems 
1. MAIN ACHIEVEMENTS 
FROM 2016 TO 2021 
1.1 BS-MFC Operational High Level Architecture 
and Users 
BS-MFC was the last centre to enter in the Copernicus Marine 
Service framework in 2016: after a ramp-up phase of 6 
months (Apr-Oct 2016), BS-MFC operational services were 
launched in Oct 2016, including BS-MFC Dissemination Unit 
‘DU) for products delivery, Production Units and Local Service 
Desk. In April 2018, BS-MFC technical Interfaces were 
mMigrated to Central DU. A high level architecture as in Figure 
' has been implemented since the beginning of the service: it 
zonsists of three Production Units - Physics (BS-PHY) run by 
ZMCC, Biogeochemistry (BS-BIO) run by ULiege and Waves 
'BS-WAV) run by HZG - which are responsible for the 
3perational production of Near Real Time (NRT) and Multi- 
Year (MY) products over the Black Sea basin (Figure 2). The 
PUs are directly connected to upstream data - observations 
and atmospheric forcing. A Local Service Desk (LSD, 
maintained by CMCC and I0-BAS) is continuously supporting 
users, through the Service Desk, and Production Units for the 
operational maintenance and monitoring of product 
avallability. 
Evolution of technical interfaces, discussed with the Technicai 
Working Group, is guaranteed by an Expert Technical Team, 
which cooperates with operational and LSD groups. PUs 
implement science-driven tasks for service evolution, In 
collaboration with USOF, that leads product quality activities, 
and NIHWM, that is responsible for the Danube River 
hydrological measurements and forecast. Each PU 
implements a Backup Unit, for production recovery in case of 
IT failure, and an Archiving Unit for superseded products, 
made available to users upon request. 
Production pipelines offer daily analyses, simulation and 10 
days forecast, while, twice per year, they deliver updated 
timeseries of reanalysis. The operational products are 
validated using available satellite and in-situ data in a 
zontinuous and consistent manner, adopting standards 
nherited from GODAE/OceanPrediet and MERSEA/MvOcean.
