Downscaled Climate Projections for Torres Strait Region at 8 km Resolution

Raster datasets provide downscaled climate change scenarios at 8 km resolution for the Torres Strait and Papua New Guinea regions. The data includes estimated mean surface relative humidity, wind speed, rainfall rate, and surface temperature for 1990, 2055, and 2090, with relative changes calculated. The projections were generated by CSIRO using the Conformal Cubic Atmospheric Model (CCAM) under the A2 high emissions scenario.

Use Cases

• Projecting future temperature changes based on surface temperature estimates for 2055 and 2090.
• Analyzing shifts in precipitation patterns based on rainfall rate projections.
• Modeling changes in atmospheric conditions based on wind speed and relative humidity estimates.
• Assessing climate change impacts relative to a 1990 baseline using the provided relative change data.

Strengths

• Data provides projections for three distinct time periods: 1990, 2055, and 2090.
• Scenarios are downscaled to a high 8 km spatial resolution for detailed regional analysis.
• Projections are based on six global climate models deemed to have acceptable skill for the region.
• The underlying CCAM model includes a detailed set of physical parameterizations described in the methodology.

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 specific regional focus.

Collection Method

Dynamical downscaling using the Conformal Cubic Atmospheric Model (CCAM) at 60 km global resolution, with further downscaling to 8 km for the target region.

Time Range

Projections for years 1990, 2055, and 2090, based on simulated conditions for periods 1980-1999, 2046-2065, and 2080-2099.
