Goal and impact
The system aims to provide the Netherlands and the BES islands with daily weather forecasts and warn of weather extremes by issuing codes.
Considerations
The algorithm system simplifies the process of processing the (physical) data from our weather stations. It ensures that the meteorologist has reliable information when preparing weather forecasts and warning of weather extremes.
Human intervention
The meteorologist determines what inputs of data and parameters are used for the system. When delivering the product (the weather forecast), the meteorologist does the interpretation and prepares the forecast.
Risk management
The algorithm system is included in the algorithm register for transparency. There are few risks in this algorithm system. It supports the meteorologist in his work.
Legal basis
The system is used in the performance of KNMI's statutory weather-related tasks.

Operations
Data
The KNMI uses data from observations of KNMI weather stations in the Netherlands and the BES islands, data from satellites, and from other countries.

Technical design
The technical system is a NWP (Numerical Weather Prediction model). At its core is the physics-based HARMONIE model. This is being developed by the ACCORD consortium (of which KNMI is a member). It runs on a High Performance Computer (HPC on Iceland from the UWC West Consortium). Post-processing steps are then applied and at the last, various products are generated. These products (including maps) are used in KNMI's weather room by the meteorologist, but are also made available in an automated way on www.knmi.nl and in the KNMI app, among others. Furthermore, various (automated) products are shared with our partners in the chain, including NIPV, safety regions, operational parties in the safety chains, such as police and fire brigade; knowledge partners such as CBS, RIVM, TNO and universities; water boards; LVNL; RWS, PBL, ILT; and Ministry of Infrastructure and the Environment; commercial weather companies.

Model system for the Climate Scenarios for the Netherlands
Royal Netherlands Meteorological Institute
This system helps KNMI understand how the climate is changing in the Netherlands and on the BES islands (Bonaire, Sint Eustatius and Saba). To this end, KNMI produces climate scenarios: clear stories and figures about how the climate may change in the future. The KNMI uses this knowledge to inform society and provides advice and warnings about the consequences of climate change.Last change on 1st of October 2025, at 7:41 (CET) | Publication Standard 1.0- Publication category
