Dear all,

I downloaded several years (2000 to 2020) of ERA5 Land hourly data for Total Evaporation using the API, in NetCDF format. The resulting file seems to be corrupted, as it shows a lot of flat time series with the same value. However, if I download it without using the API (directly from the portal) it seems to work.

This error has been independently confirmed by a colleague.

Can someone look into this, please?

Thank you.

Best regards,  
Gonzalo

Dear Gonzalo,  
I had exactly the same behaviour considering era 5 pressure database. However launching some weeks after the application through the API reworked.

If it can help
