Introduction

We have a temporary but working version of the new tool grib-check available for CARRA/CERRA to try. 

It has been updated with all related CARRA/CERRA more recent stuff (i.e. monthly/daily means, some newer parameters not existing in the first phases of the project etc.)

The temporary, still in progress, version can be downloaded from: https://drive.google.com/drive/folders/1Hq3EoDaA1EQtk2PRfWaTwc6S57Otmzvs?usp=drive_link

Follow the instruction in README to install and run it.

The tool was run on all full sample  moda/dame data in class=rr, for all origins:

Results

The outputs of grib-check with some issues are attached.

identified issues in moda/dame streams full sample data from all origins:

SE-AL-EC
  • still in development (marsscratch only)
  • not correct paramIDs are used to encode moda/dame fields (the same ones as for instantaneous should have been used)
    • SD-80276 - Getting issue details... STATUS
NO-AR-PA
  • high/medium/low cloud parameters use the WMO rather than originally required UERRA more specific definitions:
  •   WMO surface runoff 231010 is used instead of UERRA one 174008
    • grib-check should fail with "FAIL: Could not find parameter" message
      • currently it shows rather that another parameter was identified instead (231010) = to understand the root-cause..
  • accumulated fluxes are not fully correctly encoded as on Predefined level
    • scaledValueOfFirstFixedSurface and scaleFactorOfFirstFixedSurface should be MISSING
  • Time integral of snow evaporation flux (235072) has no bitmap
NO-AR-CE
  • newly archived volumetric soil ice 260644 is not archived as soil layer as other UERRA param
Surface roughness (climatological) (173)

To be clarified if it is changing or static fields as per SD-80276 - Getting issue details... STATUS

  • CERRA - pending confrimation from Waheed Iqbal 
  • CARRA as per Eivind Stoeylen 

    • In the CARRA system we have roughness at forecast time which is used in the model. This parameter is however unfortunately not archived in MARS.

    • We also have roughness lengths at analysis time which ARE archived in MARS. These are however climatological ones and not varying! We will omit including these for our daily/monthly products.
