- An error in the retrieval of high-frequency data (daily/subdaily) from NCEP seasonal forecast data (NCEP CFSv2) data. This has been documented as "known issue" E7 (C3S Seasonal Forecast known issues)
It affects all data available in the high-frequency (daily/subdaily) datasets:
Seasonal forecast daily data on single levels (seasonal-original-single-levels)
- Seasonal forecast daily data on pressure levels (seasonal-original-pressure-levels)
Members with start time at 06h,12h and 18h are not being retrieved from the archive by the CDS and just members with start time at 00h are returned.

- An error in the processing of surface solar radiation variables for NCEP has been reported (Known issue E6 in the "not fixed issues" section here)
- The parameters "surface net solar radiation" and "surface solar radiation downwards" (and their counterparts in the monthly statistics and anomalies datasets) have been accidentally swapped with each other in the case of
- Forecasts with nominal start dates from October 2019 to February 2020 (both included)
- Hindcasts with nominal start dates October, November, December, January and February
- A fix has been already introduced in the operational production of C3S data; starting from nominal start date March 2020 real-time forecast data (and its corresponding hindcasts) will not be affected by this.
- A recovery process for the affected data already published will be put in place. Details about when this will become available will be announced here.
- The parameters "surface net solar radiation" and "surface solar radiation downwards" (and their counterparts in the monthly statistics and anomalies datasets) have been accidentally swapped with each other in the case of
