Palaeo Stochastic Climate Data for Greater Sydney Water Strategy

Greater Sydney's water strategy modelling uses 10,000 replicates of 130-year daily rainfall and potential evapotranspiration data, generated by University of Newcastle researchers. The data combines observed records with palaeoclimate information. This specific asset includes data for 12 SILO weather stations, such as Blackheath, Oberon, and Lithgow.

Use Cases

• Assessing long-term water security based on 130-year stochastic climate replicates.
• Calibrating hydrological models using daily rainfall and potential evapotranspiration data.
• Evaluating climate variability impacts on water supply for specific SILO station locations.
• Incorporating palaeoclimate information into modern water infrastructure planning.

Strengths

• Contains 10,000 stochastic replicates for robust probabilistic analysis.
• Each replicate provides 130 years of daily data for long-term trend assessment.
• Data is explicitly used for the Greater Sydney Water Strategy, indicating applied relevance.

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 12 listed SILO stations.
