Stochastic Climate Data for Water Modelling in Greater Sydney

Greater Sydney stochastic climate data includes 10,000 replicates of 130-year daily rainfall and potential evapotranspiration datasets. The data was generated using observed data, both with and without combined palaeo climate data. This work was undertaken by researchers at the University of Newcastle for the Greater Sydney Water Strategy.

Use Cases

• Stress-test water supply models based on 10,000 stochastic climate replicates.
• Analyze long-term rainfall variability patterns using 130-year daily sequences.
• Model potential evapotranspiration impacts on water balance under different climate scenarios.
• Incorporate palaeoclimate-informed stochastic data into hydrological risk assessments.

Strengths

• Contains 10,000 stochastic replicates, enabling robust probabilistic analysis.
• Each replicate provides 130 years of daily data for two key climate variables.
• Includes a version informed by combined palaeoclimate data, extending the climate context.

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 data_gov_au, being specific to Greater Sydney.
