Technical issue fixed on ERA5.1 CDS API

On 20th May 2020, we announced that due to an unforeseen technical issue on the CDS API service, ERA5.1 data from the "oper" stream only could be retrieved, regardless of the value of the stream key in the API script. In other words, by default, the stream key was set to "oper" and any other stream key values were ignored. This means that if, for example, you requested ERA5.1 monthly mean data, the data retrieved is not monthly mean data but data from the hourly (oper) stream.

We have now fixed the problem and carried out substantial tests to check that ERA5.1 data from all available streams can indeed be retrieved as expected. 

Unfortunately this means that if you retrieved ERA5.1 anytime before 20/05/2020 08:00am UTC on the following streams, you will need to request for the data again:

wave, enda, edmo, ewmo, edmm, ewmm, ewda, moda, wamd, mnth, wamo

Note that request for ERA5.1 submitted before 20/05/2020 08:00am UTC but currently waiting in the CDS queue do not need to be cancelled.

We are sorry for the inconvenience this may have caused.
