MERCATOR OCEAN JOURNA: 
SEPTEMBER 2021 
A strong coordination process is established to ensure 
this cross-cutting PQ activity, involving all MFC/TAC 
production centres (18) and more than 60 PQ experts. Two 
organizational elements are in place to ease coordination: 
the Product Quality Coordination team, managed by 
Mercator Ocean International, 
-the Product Quality Working Group (PQWG), gathering 
up to 60 thematic PQ experts, assigned by production 
units to ensure regional expertise on blue, green and 
white observational and modelled products. 
The PQ coordination takes around 3 person-years in order 
to ensure: 
management and evolution of the product quality 
information (including PQ documentation evolution 
and review process), 
design, Implementation and operational maintenance 
of the PQ-Dashboard, 
collection of metrics provided by the different 
organizational elements (plus implementation of any 
required operational processes needed to manage 
them), 
facilitation of PQWG meetings and Copernicus Marine 
Service PQ representation in different forums, 
definition of Copernicus Marine Service PQ strategy 
and reporting activities. The PQWG is a unique forum, 
enabling the exchange of methods and expertise 
between product quality experts, and across common 
variables and metrics. It is a key organizational 
element to ensure the needed (bottom-up and top- 
down) exchanges about PQ within the Marine Service
