I am adding a sample for template 4.120 |
https://github.com/wmo-im/CCT/wiki/Teleconference.10.January.2024 notes: Anna provided an editorial review; @SibylleK to validate samples |
For a pure technical validation, I was able to read the entries in section 4 of the GRIB example file PDTN_120.grib2 with a DWD GRIB reader software. |

Initial request
This proposal extends the existing templates 4.5 and 4.9 for probability forecasts by additional keys which allow to encode the ensemble size of large ensembles and the type of ensemble forecast from which the probabilities are derived.
A branch with an implementation of this template is accessible under:
https://github.com/ecmwf/eccodes/tree/feature/ECC-1705-probabilitiesWithFocalStats
Amendment details
ADD the following templates entries in code table 4.0.
ADD Template 4.119 - Probability forecasts from large ensembles at a horizontal level or in a horizontal layer at a point in time.
ADD Template 4.120 - Probability forecasts from large ensembles at a horizontal level or in a horizontal layer in a continuous or non-continuous time interval.
Add to table 4.7: Derived forecast
