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.
