The availability of UERRA parameters from each of 9 model outputs listed below should reflect the real content of UERRA data archived in MARS.

For exact list of archived steps, levels etc for each model and forecast type refer to the Parameter page.

List of UERRA datasets

In the parentheses there are MARS origin, stream and version keywords valid for given dataset.

*remarks:

  • 1: In COSMO model the levels above 100hPa are not available.
  • 2: It is an analysis of total precipitation accumulated between 6h of the previous day and 6h of the day encoded in the GRIB2. The information about the accumulation period cannot be encoded in such GRIB2 files of "an" type!
  • 3: Model level increases with height for MO and decreases for other models. Model level number differs among models.
  • 4: Soil levels differ among models.
  • 5: In HARMONIE only steps up to +6h are available for soil level parameters
  • 6: step 0 is not available at COSMO forecasts ("fc") because of nudging assimilation technique
  • 7: should be archived as type=an!
  • 8: AN eps data generated by MESCAN has a different scanning mode (=64) encoded than FC eps data generated by SURFEX (scanning mode is 0). This should be fixed because of potential implications for users.
  • 9: COSMO, deterministic data will be not archived in UERRA scope but probably in 2018 after the project end
