New dataset: HARMONIE KEPS
News item | 27-09-2021 | 13:33
Now also available on the KNMI data platform: the HARMONIE-AROME KEPS package. It concerns the output of the KNMI Ensemble Prediction System (KEPS) based on a KNMI version of HARMONIE-AROME, with 10 ensemble members.
This dataset contains current grid point information in the form of selected fields from the original calculation area of the HARMONIE model from KNMI. The dataset gives an impression of the margin of reliability of the model run.
The data is daily available from the model runs based on the analyzes of +00h = 00, 06, 12, and 18 UTC. The required calculation time is 2.5-3 hours.
- Calculation grid: Lambert projection
- Product resolution: 0.05° west-east and north-south (340x340 points)
- Grid representation: Rotated Lat/Lon
- Area definition: North 8.45°N South -8.5°N / East 11.45°E and West -5.5°W, South Pole at -38.0°N and 0.0°E.
- Time steps: +00h (+1h) +48h
- File size: approx. 2.5 Gbytes per 48-hour model run
- Parameters: single level parameters
