| Provider: | Danish Meteorological Institute, DMI, Denmark. |
| Model scope: | Europe |
| Update frequency: | every 3 hours |
| Resolution: | 1.1nm, 2.0km |
| Model duration: | 31 forecasts starting at 0 hr, ending at 2 days 12 hrs |
| Parameters: | pressure, wind, wind gust, cloud, temperature, visibility |
| GRIB model date: | Wed Feb 5 03:00:00 2025 UTC |
| Download date: | Wed Feb 5 06:14:52 2025 UTC |

Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.
Description
The Danish Meteorological Institute (DMI) provides several models which are of interest. This is their Denmark, Iceland, Netherlands and Ireland (DINI) model, which is referred to as DMI Europe in LuckGrib.
DMI uses and codevelops the weather model HARMONIE. The weather model produces forecast data for e.g. temperature, dew point temperature, cloud cover, wind, pressure and several others parameters. DMI’s weather model HARMONIE is available in two different versions that cover the geographical areas of Iceland and Greenland (IG) and Denmark, Iceland, Netherlands and Ireland (DINI), respectively. Both versions of the weather model uses a grid resolution of 2 km. DMI’s HARMONIE model runs cycle 43h with boundary conditions from the global weather model ECMWF.
The model focuses on events that take place on small scale but can have serious outcomes, e.g. extreme precipitation like cloudburst (convective precipitation) and rapidly changing storm low.
HARMONIE is an abbreviation of Hirlam Aladin Research towards Mesoscale Operational NWP in Europe and is developed through an international collaboration. Hirlam and Aladin are the names of two groups of meteorological institutions in Europe, therefore HARMONIE has a broad European foundation.
This model offers a spatial resolution of 2km x 2km, which is fine enough to resolve small weather features. The model is updated every three hours.
The combination of its resolution, wide coverage area and frequent updates should make this model one of the favorites for sailors within its coverage area. While there are several smaller regional models with comparable resolution, if you are sailing in the boundary area toward the edges of those smaller models, you will have a problem in choosing which model to use. This larger model should resolve this issue for many situations.
This model was released to the public by DMI in early 2024 and was added to the LuckGrib collection in February 2025. Thank you to the entire DMI team responsible for making this data available.
