The regular update of the YOPP archive at ECMWF has ended by the end of 2020.

The additional period with tendencies from various physical and dynamical processes on model levels have been added to YOPP dataset. The total period is now 2017-07-12 ... 2020-03-31. Find more information here about the tendencies on model levels.

Eight additional parameters coming from the coupled ocean model were added to the YOPP dataset. Two of them (sea water velocities) are available for the whole period and the remaining six since 12 June 2019. Exact list of those parameters can be found in the page YOPP/Description

The ECMWF YOPP archive based on ECMWF's ENS IFS forecast outputs was launched on the 15th of May, 2017. The 1^st archived model run is from  the 1^st of May. The archive is accessible via standard ECMWF's access tools (Web-MARS, Web-API) or a newly created dedicated data portal.
