ägure 5: User Feedback thematıc. 
Every feedback item <collected over the period is 
considered, aggregated and inter-compared and give rise 
to requirements with different weights. 
Higher weight is given to: 
same request from several users, 
request from a regular user (user that downloads 
products at least three times in different weeks within 
the period of one month), 
- request with common sense. 
2.2. Main user requirements 
Ihe main requirements identified over the years are: 
provide higher spatial and temporal resolution 
for products: this requirement is continuously 
considered. Resolution is a key priority and it has 
globally increased over the years following scientific 
and technical state-of-the-art capabilities, 
add wave products: Near real time and reanalysis 
model wave products for each ocean basin have been 
continuously added since 2017. Satellite and in situ 
wave products are also distributed since 2019, 
add model wind and atmospheric products: this 
requirement cannot be taken into account (yet) as it 
depends on the data policy from Numerical Weather 
Prediction centres, 
ease the choice of, and access to, products for non- 
experienced users: several updates were made, but 
there are still some improvements to be done. It is 
foreseen to provide an advanced catalogue search 
and catalogues by thematic applications (as Marine 
Strategy Framework Directive, Sea Ice services), 
-download more easily very large datasets: this 
requirement is not yet fully taken care of and is part 
of an ongoing effort, 
- provide an OPeNDAP (a protocol to get data remotely) 
access: this service will be available at the end of 
2021, 
allow the use of various softwares (e.g., matlab, GIS): 
This will be possible thanks to OPeNDAP access. 
3. CONCLUSIONS AND FUTURE PROSPECIT. 
Juring the 2015-2021 Copernicus period, service monitoring 
and user requirement activities have allowed to: 
carefully monitor the Copernicus Marine Service, and 
-steer its evolution and user uptake. 
Within the next 2021-2027 phase, those two activities 
will be reinforced and relationships with policy and major 
accounts will be strengthened to transform them into key 
strategic accounts. MOi will manage and contribute to: 
develop a dedicated offer catalogue for each of the 
policy and major accounts, 
-ensure that the products and services developed and 
operated are fully aligned with the activities and plans 
of the European Union. 
Moreover, an independent operational User Requirements 
Database will be built and maintained and an externa 
component will be set up to evaluate independently 
the efficiency and overall performance of the service. 
Derformance will be assessed mainly toward users’ 
information needs and high-level requirements and the 
fitness-for-purpose of the Copernicus Marine Service with 
a specific emphasis on the needs of EU Policies.
