KNMI'23: Regional Climate Model Data for River Discharge Calculations

KNMI'23 climate scenario data provides 240 years of daily regional atmospheric model outputs across eight 30-year ensembles. The dataset was produced by the Dutch Ministry of the Interior and Kingdom Relations and used by Deltares to derive river discharges. It includes daily fields for temperature, precipitation, and potential evapotranspiration required for hydrological calculations.

Use Cases

• Projecting future river discharge volumes based on daily precipitation and temperature scenarios.
• Validating hydrological models using the provided daily potential evapotranspiration data.
• Analyzing climate change impacts on regional water systems using the multi-ensemble, multi-horizon model outputs.

Strengths

• Data spans 240 years across eight distinct 30-year ensembles, providing a substantial basis for scenario analysis.
• Includes the core daily variables (temperature, precipitation, potential evapotranspiration) explicitly required for discharge calculations.
• Scenario data is derived from the RACMO v2.3 regional climate model, which is a recognized tool for downscaling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
