A METAR is a weather observation report for aviation, which is routinely prepared every half hour on HH+25 and HH+55 hours for Dutch airports. The measurement data used as...

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...

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...

Forecasts of radar reflectivities at 1500 m over the Netherlands and surrounding area measured by two radars in Herwijnen and Den Helder. Forecast interval is 5 minutes, with...
