5-Minute Radar/Gauge Precipitation Accumulations Over the Netherlands

Starting from 31 January 2023, this dataset provides gridded 5-minute precipitation accumulations. The data is derived from Dutch, Belgian, and German radars and corrected using automatic and manual rain gauge measurements. It is produced by the Ministerie van Binnenlandse Zaken en Koninkrijksrelaties using improved algorithms for signal attenuation and vertical variation.

Use Cases

• Modeling flash flood risk based on 5-minute precipitation accumulations.
• Calibrating weather radar algorithms based on the described gauge-correction methods.
• Analyzing the movement and intensity of fast-moving showers based on the corrected radar data.
• Validating numerical weather prediction models for the Netherlands and surrounding area.

Strengths

• Data is corrected for multiple error sources, including signal attenuation and vertical variation of precipitation.
• Integrates measurements from multiple national radar networks (Dutch, Belgian, German) and rain gauges.
• Provides high-temporal-resolution data with a 5-minute accumulation interval.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The last update date is unknown; freshness is unverified.
