FIXED: Major technical issue on the Climate Data Store

,

As many of you have experienced and started reporting at the end of last week, we can confirm on behalf of the Climate Data Store team that there is an ongoing technical issue on the Climate Data Store (CDS) affecting all data retrievals and resulting in significantly increased queueing times.

We are very sorry for the inconvenience this is causing our users.

In the meantime, please be assured that the Climate Data Store team is making every effort to get this issue fixed as soon as possible.

We will post an update as soon as we will have details to share.

We thank you for your patience.

Hello Anabelle, thanks for letting us know.

Do you have any updates here?

Hi all,

We are pleased to let you know that the Climate Data Store is back!

The Climate Data Store team fixed the issue last night and systems are fully operational again (queues might still be a bit longer than usual while the backlog is being cleared).

Our apologies again for the inconvenience this may have caused.

Dear all,

Thank you very much for the updates.

For me is still not possible to download ERA5-Land data through the API due to errors during the transfer.

Best,
Diego

Hello,

I still have the same problem: I’ve been in the queue for one day. I am a student, and I need to download the data for my master’s thesis. Is there any solution?

Hello,
I still get a long queue time, don’t know how long will it take to complete the accumulated requests or it is beacuse the issue is not completely fixed yet.

Regards,

The ERA5 queue seems back to normal,

But ERA5 LAND is still pretty much unusable.

Any chance of a fix?

Hello,

I’m also requesting for a fix about ERA5-Land product, the limit of 20 active processes vs more than 1500 queues in simply unrealistic. When does it will be increased?

The Climate Data Store team is investigating an issue with ERA5-Land. We have no further information to share at this time.
Thank you for your patience.

Hi! Most of the CAMS Global Composition Forecasts data has been unavailable for the past week. I always get “The tape on which the data reside is unavailable” whenever I try to request a data item. When will this problem be resolved? Thank you!

I still cant download more than 1 year at time even though it was said that june it would be working full capacity. For the past weeks I have been downloading data monthly since 1961 and thats time-consuming. When are we going to be able to download large amount of data at once?

The CDS performance with respect to ERA5-Land data download is linked to users’ behaviour. Some users are making very large requests of ERA5-Land data in NetCDF file format impacting the system memory and therefore degrading the CDS performance for all users.

We urge users to respect the current rules in place for downloading all ERA5 data, including ERA5-Land, i.e. no more than 6000 items at a time, no more than one month of data at a time, preferably in GRIB native format.

Should the issue persists, the Climate Data Store administrator will cancel large data requests and may have to implement further restrictions to allow fair data access to everyone.

Thank you for your cooperation.
