NARCliM2.0: High-Resolution Climate Projections for Australia, 1950-2100

NARCliM2.0 provides high-resolution regional climate projections for Australia, developed by the NSW Government with support from other Australian governments and universities. The dataset offers continuous simulations from 1950 to 2100 at 4km and 20km grid resolutions, using five CMIP6 global climate models and two regional climate models under multiple emissions scenarios. It was released in phases from 2024 to 2025 and is designed to World Climate Research Programme CORDEX standards.

Use Cases

• Assessing future climate change impacts based on multiple greenhouse gas emissions scenarios (SSP1-2.6, SSP3-7.0, SSP2-4.5).
• Conducting climate risk analysis for southeastern Australia based on 4km convection-permitting resolution data.
• Analyzing long-term climate trends and extremes using the 30 released climate indices for the period 1950-2100.
• Planning for infrastructure and community resilience in five capital cities covered by the high-resolution domain.

Strengths

• Provides the most detailed regional climate projections available in Australia to date with a 4km grid resolution.
• Covers a continuous 150-year time period from 1950 to 2100 for historical and future analysis.
• Uses a rigorously selected ensemble of five independent CMIP6 global climate models to represent a wide range of future climates.
• Adheres to international WRCP-CORDEX standards for data quality and interoperability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment for specific computational needs.
