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...

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

Probability forecasts for possible dangerous weather, based on weather model output from the ECMWF atmospheric ensemble model. Probabilities are uncalibrated. Available are forecasts for visibility (f...

Current operational HARMONIE information in gridded form (regular lat-lon) of weather parameters from the KNMI HARMONIE-AROME Cy43 model. The output frequency is 1 hour. Please note: only the last 72 ...

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 ...

Current operational HARMONIE information in gridded form (rotated lat-lon) of selected parameters at all model levels from the UWC-West HARMONIE-AROME Cy43 model. For this weather forecast model, KNMI...

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...
