Greater Sydney Stochastic Climate Data for Hydrological Modelling

Greater Sydney stochastic climate data consists of 10,000-year daily datasets of rainfall and potential evapotranspiration, generated using observed data combined with palaeo-climatic records. The data supports hydrological assessment and regional water planning for the Greater Sydney area. It was developed by researchers at the University of Adelaide and the University of Newcastle and is used in Regional Water Strategies.

Use Cases

• Long-term hydrological risk assessment based on 10,000-year stochastic climate replicates.
• Water strategy planning using synthetic daily rainfall and evapotranspiration data.
• Model validation and calibration using datasets that incorporate palaeo-climatic variability.
• Climate impact studies on water systems leveraging multiple evapotranspiration calculation methods (e.g., Morton's, Penman-Monteith).

Strengths

• Contains 10,000 replicates of daily climate data, providing a large ensemble for probabilistic analysis.
• Includes detailed metadata and quality assurance documents for each climate station.
• Integrates palaeo-climatic data to extend the range of climate variability beyond the instrumental record.

Limitations

• Specific row counts, column names, and dataset size are not provided in the available metadata.
• License (CC-BY-NC-ND-4.0) restricts commercial use and derivative works.
• Data is limited to the Greater Sydney region, not applicable for other geographic areas.
