Change to NCAR RDA ERA5 dataset, ds630.0 web access to be removed on Oct 1.

The currently available, full time-series of ERA-5 has been published under ds633.0 -ERA5 Reanalysis (0.25 Degree Latitude-Longitude Grid) https://rda.ucar.edu/datasets/ds633.0/#!description.  Data are now available from 1979 to the present in ds633.0, and it will continue to be extended in time. Data from 1950 to 1978 will be added once they become available in the Copernicus Climate Data Store. Processing and archiving of data to ds630.0 -ERA5 Reanalysis, https://rda.ucar.edu/datasets/ds630.0/#!description has been discontinued and the web access will be removed on Oct 1, 2019.

For background, processing and publication of data to ds630.0 was stopped in April, 2019, due to the length of time it was taking to update that dataset.  It was estimated that it would take around 6-7 years to download, process, and archive data in ds630.0 using legacy strategies, versus around 1 year to download, process, and archive the full time series (1950 - present)  of the 0.25x0.25 gridded data staged online in the Copernicus Climate Data Store.

We encourage you to modify all RDA supported ERA-5 workflows to use ds633.0, https://rda.ucar.edu/datasets/ds633.0/#!description as soon as possible.

Would you like to perform data analysis on NCAR RDA maintained data without the need to move it?

Would you like to perform computational analysis on NCAR RDA maintained dataset collections without the need to transfer the data to your local system?  Many in the US University research community are eligible to get allocations on NCAR CISL computing resources, which provide direct read access to most RDA dataset collections.  An overview of all of the CISL allocations programs is provided at https://www2.cisl.ucar.edu/user-support/allocations.  Typically, data analysis workflows only require a Small Allocation Request.  US University users supported by NSF grants should follow the instructions found under "University - Small Request"to submit a request for a small allocation to perform data analysis processing.  If you are a US University Graduate Student or Postdoc, you might have eligibility to apply for a "University Grad/Postdoc Small Allocation Request"even if you are not supported by a NSF grant.  We encourage all who may be eligible to explore the option of using CISL supported compute resources to perform their data analysis tasks, as it could be much more efficient than waiting for large volumes of data to transfer to your local compute resources.

Change to NCAR RDA maintained ERA5 dataset, ds630.0 no longer updated

The full time series of the RDA maintained ERA-5 dataset is being made available under ds633.0 -ERA5 Reanalysis (0.25 Degree Latitude-Longitude Grid) 
https://rda.ucar.edu/datasets/ds633.0/#!description.  We expect ds633.0 to include data from 1979 - present by the end of Sep, 2019.  Processing and archiving of data to ds630.0 ERA5 Reanalysis, https://rda.ucar.edu/datasets/ds630.0/#!description has been discontinued and the web access will be removed within the next two months, once the full time range has been made available in ds633.0.

For background, processing and publication of data to ds630.0 was stopped in April, 2019, due to  the length of time it was taking to update that dataset.  It was estimated that it would take around 6-7 years to download, process, and archive data in ds630.0 using legacy strategies versus around 1 year to download, process, and archive the full time series (1950 - present)  of the 0.25x0.25 gridded data staged online in the Copernicus Climate Data Store.
