Current operational HARMONIE ensemble information in gridded form (rotated lat-lon) of near surface parameters from the UWC-West HARMONIE-AROME Cy43 model. For this weather forecast model, KNMI works ...

In the frame of the CAMS NCP for the Netherlands, KNMI issues daily a 4-day air quality forecast for the Netherlands using the LOTOS-EUROS chemical transport model.

Based on the MSG-CPP cloud products (cloud physical properties retrieved from Meteosat measurements) a forecast/nowcast of these cloud properties is made and converted to surface downwelling shortwave...

Global Lightning Imager Level 2 (GOES-East) 10 minutes aggregrated flash events. GOES satellites provide continuous weather imagery and monitoring of meteorological and space environment data across N...

A SIGMET is a warning for (large) aviation that reports on (un)foreseen dangerous weather conditions and should therefore be treated with priority. The area for which the KNMI issues a SIGMET is the A...

This dataset contains horizontally averaged statistics from unvalidated Dutch Atmospheric Large Eddy Simulation (DALES) forecasts with a lead time of 24h. The LES is ran using the Ruisdael branch of D...

Data Quality Warning: Data released prior to 2025-07-10 is unreliable due to a configuration error. Please disregard affected data. A gridded 51-member ensemble of precipitation forecasts that are cre...

Warning for aviation reporting unforeseen dangerous weather conditions up to FL100 in the Amsterdam FIR, including the concession area in the North Sea (North Sea Area V). An AIRMET is issued maximal ...

A selection of weather model parameters, including aviation parameters. It concerns near surface and boundary layer parameters (up to ~3000m) of the UWC-West HARMONIE-AROME Cy43 model, for the Dutch d...

The TAF (Terminal Aerodrome Forecast) is a weather forecast for an aerodrome or airport. At KNMI, the TAF is produced for the civil airports of Amsterdam/Schiphol (EHAM), Rotterdam/The Hague Airport (...
