Additional variables in the single level entry

It is our pleasure to inform you that the “Arctic regional reanalysis on single levels from 1991 to present” CDS catalogue entry had been updated with 27 new variables (see at https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-carra-single-levels).

The list of new variables is as follows:

  •     2m specific humidity
  •     Total column cloud liquid water
  •     Total column cloud ice water
  •     Total column graupel
  •     Time integral of rain flux
  •     Time integral of total solid precipitation flux
  •     Precipitation type
  •     10m eastward wind gust since previous post-processing
  •     10m northward wind gust since previous post-processing
  •     10m wind gust since previous post-processing
  •     Time integral of snow evaporation flux      
  •     Time integral of surface latent heat evaporation flux
  •     Time integral of surface latent heat sublimation flux
  •     Direct solar irradiation
  •     Surface net solar radiation, clear sky
  •     Surface net thermal radiation, clear sky
  •     Top net solar radiation
  •     Top net thermal radiation
  •     Time integral of surface eastward momentum flux
  •     Time integral of surface northward momentum flux
  •     Fog (lowest model level cloud)
  •     Fraction of snow cover
  •     Snow albedo
  •     Surface roughness length for heat
  •     Sea ice surface temperature
  •     Snow on ice total depth
  •     Volumetric soil ice

Please note that unfortunately there are some small gaps in the new dataset. This means 38 days missing for the CARRA-East and 44 days for the CARRA-West domain (less then 0.4% of the entire new data volume). More details on these gaps are at https://confluence.ecmwf.int/x/p3ltD#CopernicusArcticRegionalReanalysis(CARRA):knownissuesanduncertaintyinformation-Knownissues These gaps are planned to be covered in Q1 2023.
