Downscaled Bioclimatic Projections for Australia (1975-2099) at 5 km Resolution

19 bioclimatic indices calculated from CMIP6 climate models for Australia from 1975 to 2099. The data is dynamically and statistically downscaled to a 5 km resolution for three emissions scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0). This dataset is provided by the Terrestrial Ecosystem Research Network's Data Discovery to support the study of climate change impacts on species distributions.

Use Cases

• Modeling future habitat suitability for Australian species based on projected bioclimatic indices.
• Assessing climate change risks to biodiversity across different emissions scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0).
• Conducting conservation planning and identifying potential climate refugia using high-resolution (5 km) climate data.

Strengths

• Covers a 124-year time range from 1975 to 2099.
• Provides data at a high spatial resolution of 5 km for the entire continent of Australia.
• Includes projections for three distinct Shared Socioeconomic Pathway (SSP) emissions scenarios.

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 data_gov_au, focusing solely on Australia.
