Stochastic Climate Data for Water Modelling in Greater Sydney

University of Newcastle researchers generated this stochastic climate dataset for the Greater Sydney Water Strategy. It contains 10,000 replicates of 130-year daily rainfall and potential evapotranspiration data. The data was last updated on 2026-05-12.

Use Cases

• Stress-testing water supply models based on 10,000 stochastic replicates of climate data.
• Assessing long-term water availability based on 130-year daily rainfall projections.
• Evaluating the impact of climate variability on potential evapotranspiration for hydrological planning.

Strengths

• 10,000 stochastic replicates provide a robust probabilistic foundation for modelling.
• 130-year daily time series enable analysis of long-term climate variability.
• Data is explicitly generated for use in the Greater Sydney Water Strategy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the nine listed Silo stations in Greater Sydney.
