CEDA Archive Support for ERA5 usePosted on July 23, 2018 (Last modified on October 19, 2023) • 2 min read • 330 words
The CEDA user communirt have made great use of ECMWF’s ERA Interim reanalyis data over recent years, taking advantage of having co-hosted access to these and other data from the CEDA archives alongside their own resources within the JASMIN environment. ECMWF are presently producing their latest re-analysis product, ERA5, which promises even greater spatial and temporal resolutions as well as new parameters. However, with improved resolution comes greater data volumes, with ERA5 forecast to produce around 10 Pb worth of data by the end of 2018.
Though there is strong demand for some ERA5 data to be held by CEDA to support regular use of these data by multiple users, the complete dataset is well beyond our capacity, but CEDA are seeking to support our users’ needs where possible.
CEDA has capacity to copy around 2Pb of ECMWF data onto JASMIN disks, with options to have more on tape, through which support will look to supply data in four categories:
Details are not fixed, and we will adjust our plans to take into account user requests. More details can be seen in the following document: CEDA support for ERA5 and other ECMWF product
We welcome feedback from our user community as we continue to refine our plans for ERA5 provision.
