With the Product Release on December 2020, new datasets with higher temporal resolution, arriving also up to 15-minutes, have been added and made available from the Copernicus Marine Catalogue.
Here following the products (and datasets) concerned:
However, these 15-min datasets being novelty introduced, they have not been produced before, so unfortunately the Copernicus Marine Service is unable to provide data older than the available temporal coverage.
Key Information: there is no historical catalogue for 15-min datasets.
These historical timeseries:
"will be built through the aggregation of the best-estimates generated every day in the daily forecast run (hindcast) and/or on a weekly basis in the analysis runs"
as specified in the December2020 Transition Document.
