(forms and API) | Real-time forecast data from CMCC-CM2-v20160423 (CMCC SPSv3) data. It affects anomalies calculated using the wrong data specified in E5.a, specifically: Pressure variables: March to September 2019

| E6. | CDS retrievals
(forms and API) | Surface solar radiation variables from CFSv2-v20110310 (NCEP CFSv2) data. It affects: - forecast data for nominal start dates October, November, December 2019 and January, February 2020
- hindcast data (1993-2016) for nominal start dates October, November, December, January and February
Two variables - "surface net solar radiation" and "surface solar radiation downwards" - have been swapped with each other. This error affects the daily data and corresponding monthly statistics and anomalies. | data with a fix for the affected start dates will be provided

(forms and API) | Total cloud cover from JMA cps2-v20150526 (JMA/MRI-CPS2) data. It affects all available data for that variable (daily data, monthly data and anomalies) both for real-time forecasts and hindcast dates Due to a bug during the data ingestion to the C3S archive the values of this parameter have been divided by 100. | archived (wrong) data won't be overwritten

(forms and API) | Sea surface temperature and land surface temperature (called 'soil temperature level 1' in the CDS) from CMCC-CM2-v20191201 (CMCC SPSv3.5) data. It affects the following data for those two variables: - forecast data (daily data, monthly data and anomalies) for nominal start dates March, April, May, June and July 2022
According to CMCC report about the issue: The problem only affects the points at the borders between the three realms (sea ice, ocean and land), and is due to a change in the land-sea or sea ice-sea mask interpolation algorithm, which was implemented in the forecasts (starting from March).
Therefore, the anomalies of the above mentioned variables show unrealistic patterns near the sea-land or sea-sea ice boundaries, because, in these grid points, the new interpolation algorithm has made the forecasts, from March onwards, inconsistent with the hindcasts.
Starting from the August 2022 real-time forecast, it will be restored the procedure used in the hindcasts. | archived (wrong) data won't be overwritten | archived (wrong) data won't be overwritten |
| E11.* | CDS retrievals
(forms and API) | Sea ice concentration: Météo-France System 8 hindcasts contain an error, with one ensemble member (member number=2) for the August 2004 start date. This member was initialised without sea ice: sea ice concentration recovers gradually, reaching close to climatological levels by the end of the forecast range. Note that the error in sea ice may have an impact on other variables in this member. Analysis performed by Météo-France indicates the impact on reforecast climatology is minimal (including sea-ice itself).

(forms and API) | Sea ice concentration: BOM ACCESS-S2 hindcasts contain an error, with one ensemble member: member number = 2 for the 28/05/2008 start date (subdaily/daily data) used in the June 2008 nominal start date as member number = 13 (monthly data and anomalies).
Due to technical reasons the values for this variable and this ensemble member were wrong and the right ones were not available from BOM. In order to keep a complete set of hindcast dates for all variables, the values for this member sea ice concentration have been overwritten copying the values for member number = 1 (subdaily/daily data); member number = 12 (monthly data and anomalies) | archived data for the affected variable has been duplicated from another ensemble member | archived data for the affected variable has been duplicated from another ensemble member |
