MERCATOR OCEAN JOURNA: 
SEPTEMBER 2021 
The second achievement was to develop a scientifically 
assessed version for the delayed mode products. These 
datasets aim to address user needs to reanalysis purposes 
and climate research activities. Developments were made 
to allow their temporal extension every 6 months and to 
ease the development of Ocean Indicators in partnership 
with CMEMS partners. 
Probably the most recognizable achievement of In Situ TAC, 
as it offers lots of added-value to the whole in situ data 
Jgathered, is the harmonisation of QC procedures applied 
within all In Situ TAC centres. As a matter of facts, In Situ TAC 
performs automatic NRT QC on data and a delay mode QC 
procedure that includes visual inspection and comparison 
with other data sources. At times, providers even rely on Ir 
Situ TAC, delegating the important task of QC and become 
users of their own data to improve their local data repositories 
In the last years, important cross-cutting activities and extra 
functions have been developed. A Dashboard was created to 
facilitate data discovery, file downloading and data 
visualization.
