NARCliM2.0: Climate Projections for New South Wales at 4 km Resolution

1990-2009 to 2080-2099 climate projections for New South Wales and the ACT, developed by the NSW Department of Climate Change, Energy, the Environment and Water. The dataset includes 215 GIS-ready raster datasets per pack for seven climate variables under three emission scenarios. Data represents 20-year climatologies derived from an ensemble of 10 NARCliM2.0 climate models.

Use Cases

• Model future flood risk based on projected precipitation changes.
• Assess agricultural suitability based on projected temperature and hot day frequency.
• Plan for wildfire mitigation based on projected severe fire weather days.
• Compare regional climate impacts under low, medium, and high emissions scenarios.
• Analyze seasonal climate trends for summer, autumn, winter, and spring periods.

Strengths

• Data is provided at a high spatial resolution of 4 km for the entire NSW and ACT region.
• Projections are based on an ensemble of 10 climate models, providing a range of plausible outcomes.
• Covers seven key climate variables including temperature, precipitation, and fire weather indices.
• Includes data for a historical baseline and seven future periods spanning from 2020-2039 to 2080-2099.

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 regional climate modeling.
