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.
