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

10,000 replicates of 130-year daily rainfall and potential evapotranspiration data generated for the Greater Sydney region. The data was created by researchers at the University of Newcastle using observed climate data, both with and without combined climate data, for water strategy modelling. This particular asset contains data for nine specific Silo weather stations in the Greater Sydney area.

Use Cases

• Conducting water security risk assessments based on stochastic rainfall and evapotranspiration replicates.
• Calibrating hydrological models for the Greater Sydney area using long-term synthetic climate sequences.
• Performing uncertainty analysis in water resource planning based on 10,000 climate scenarios.
• Studying the impact of combined climate data on modelled water availability.

Strengths

• Contains 10,000 stochastic replicates, enabling robust probabilistic analysis.
• Covers a long 130-year daily time series for each replicate.
• Includes data for nine specific weather stations (e.g., DARKES FOREST, KANGAROO VALLEY) in Greater Sydney.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modelling tasks.
• Data may reflect geographic bias inherent to the selected Silo stations.
