Missing ERA5 Data for January 2026

Our API call to retrieve ERA5 data for January 2026 is only returning ERA5T data. Is there a delay in releasing January 2026 ERA5 data? Or an issue with downloading via the API?

Via the MARS system the data came in about two days ago.

Great, thank you! Can you point me to where I’m able to check the status on the MARS system?

Status of all or most ECMWF services including MARS:

MARS server activity:

I hope, that helps.

Thank you, but I’m having trouble decoding the information on those websites. Could you post a screenshot that indicates when the ERA5 data was posted for Jan. 2026 or point me to what I should be looking for? Thank you!

Sorry, I don’t know, how to get that information by a webpage or similar. I knew the answer in this particular case because I was also looking for the era5 instead era5t data - like you - just in these days (checking each day). Therefore, I knew when it popped up. However, there was no message from ECMWF that for this January era5 data is different from era5t data.

Ok, got it. Thank you!
