Abstract

PILOT: Seamless ensemble precipitation forecast probabilities up to 6 hours ahead, per 5 minutes, over the Netherlands. The forecast contains 72 time steps: +5 minutes to +360 minutes. Forecasted is the exceedance probabilities of 6 precipitation thresholds, on a grid of 1x1 km. The precipitation thresholds are 0.1, 0.3, 1, 3, 10, and 30 mm/h. The forecast is made with an experimental KNMI implementation of pySTEPS (https://pysteps.github.io). The forecast is initiated with the KNMI 5-minute real-time precipitation accumulation product (RTCOR-5m) and the HARMONIE-AROME Cy43 ensemble forecast.

NOTE: As this data product is currently in a pilot phase, please be aware that it may undergo changes or be discontinued at any time without prior notice. This pilot will last until January 31st 2026 at the latest.
