The ocean paramaters are included in the latest test samples (to be implemented in 20026)
The new fixed CNRM hindcasts have not been uploaded yet to the S2S archive, which causes their output cannot be used to compute anomalies etc from the current realtime data. Users should be warned about that (not to use previous hindcasts on current model).
=> warnings amended in CNRM Model & Models The new reforecasts will be processed asap.
RMM from CPTEC is missing
=> Frederic will check and add it to the suite to be processed in the future.
AIML related to S2S?
=> No data provider has plans to produce data driven output operationally yet (only ECMWF in experimental mode later this year)
Do we have stats who gets the most recent realtime data? That could help to reconsider current 3 weeks delay for UKMO data.
=> See statistics on usage at ECMWF
Statistics on user uptake of reduced delay
The table below shows statistics of access to real-time data (all providers) in the last 30 days split in 4 categories:
- within the 1st week of reference time (provided no-one can access data earlier than 48 hours old),
- between 1 to 2 weeks old,
- between 2 to 3 weeks old
- and the last category of requests access data that is older than 3 weeks (which includes access to UKMO data).
The numbers clearly show users are interested in early access to S2S data.
