Stochastic Climate Data for Greater Sydney Water Modelling: 10,000 Replicates

10,000 replicates of 130-year daily rainfall and potential evapotranspiration data for eight SILO stations in Greater Sydney. This stochastic climate data was generated by University of Newcastle researchers using observed data and used for the Greater Sydney Water Strategy. The dataset is provided by the NSW Department of Climate Change, Energy, the Environment and Water.

Use Cases

• Generate probabilistic water balance forecasts based on stochastic rainfall and evapotranspiration inputs.
• Stress-test water infrastructure planning models against a wide range of synthetic climate sequences.
• Assess long-term water security risks for Greater Sydney using the 10,000 climate replicates.

Strengths

• 10,000 replicates provide a large ensemble for probabilistic analysis.
• 130-year daily temporal resolution allows for long-term hydrological trend assessment.
• Data is explicitly linked to a major strategic planning effort (Greater Sydney Water Strategy).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the eight listed SILO station locations.
