Extreme Weather Indices for Marine Predators in Tasmania

Processed weather variables and extreme weather indices compiled from the Bureau of Meteorology, BARRA2 reanalysis, and CAWCR wave hindcast model examine environmental drivers for three marine predator species in Tasmania. The dataset includes daily summaries and derived measures like wet-bulb globe temperature and apparent temperature relevant to species' breeding seasons. This resource provides a transparent foundation for analyzing environmental drivers of reproductive variability, enabling replication of the associated publication's workflow.

Use Cases

• Analyze the influence of heatwaves on breeding outcomes based on derived temperature indices.
• Model the relationship between rainfall extremes and reproductive output based on percentile-based indices.
• Study the impact of wave energy and wind conditions on marine predator breeding seasons based on synoptic observations.

Strengths

• Weather data compiled from authoritative sources including the Bureau of Meteorology, BARRA2 reanalysis, and CAWCR wave hindcast model.
• Extreme weather indices calculated following BOM definitions using climatological baselines of at least 30 years where available.
• Indices produced in both binary (occurrence) and continuous (magnitude) forms to characterize heatwaves and rainfall extremes.

Limitations

• The biological data on reproductive output are not included, owned by external programs.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
