Figure 1 (left panel) shows that Mercator Ocean has been 
carefully and closely managing Its product portfolio and 
each product life cycle. There are 3 catalogue updates 
per year on average, introducing new products, improving 
existing ones and removing old ones. Along the years, the 
service has, for example, been enriched with new wave 
products, new satellite (Sentinel-3, Jason3) data products, 
Ocean monitoring Indicators (OMI), Ocean State Report 
(0SR), catalogue homogenization (CF standard names 
usage), use cases, demonstrations, trainings and roadmap

Product management has also allowed to carefully track 
all product change impacting users along with product 
metadata updates. The service has been making sure that

1.2. Service Monitoring 
KPlIs Timeliness and Avallability are measured and 
monitored for each product in the catalogue. 
Timeliness indicator measures the difference (delay) between 
the effective product delivery time and the target delivery time 
Availability indicator (factor of reliability) provides real time 
information about the presence and/or accessibility of a 
product. 
Between 2015-2020, these 2 KPlIs have been stable and 
stayed high: 98% for timeliness, 99% for availability. The 
usage of products has also been monitored and showed 
that the number of users downloading products has 
increased over 2015-2020 (Figure 1) along with the volume 
of data downloaded (from 167 TB in 2015 to 3000 TB in 
2020) (Figure 3)
