| E5b. | CDS retrievals
(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

| E9. | CDS retrievals
(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 |
