Missing (NaN) values in solar weather data for February 2023 using CDS API

Software and Tools API
1

Hi all,

I’m retrieving solar radiation data using the Copernicus CDS API (cdsapi) for multiple locations in Europe. While analyzing the time series for 2023, I noticed that some values in February 2023 are missing across different coordinates.

I’ve checked the download parameters and re-ran the requests to rule out temporary issues or client-side problems. However, the missing values persist, and they seem to occur consistently for certain time steps.

My questions:

  1. Is this a known issue with the dataset for February 2023?
  2. Is there an official way to report data gaps or quality issues?
  3. Could someone from the CDS team confirm whether the dataset has known gaps for that period?

If needed, I can provide specific request code and screenshots.

Thanks in advance for your help!
