Please be aware that in early January 2021 an issue was detected in the production of the "Near surface meteorological variables from 1979 to 2018 derived from bias-corrected reanalysis" version 1.0. causing erroneous values for the "Surface downwelling shortwave radiation" (SWdown) data. The issue has been fixed and the affected data reprocessed. The corrected data is now available from the Climate Data Store as version 1.1.
