Tropical Cyclone Debbie Corrected Wind Field, March 25–29, 2017

Geoscience Australia Data released a workflow and datasets for developing a local, corrected wind field for Tropical Cyclone Debbie. The data combines modeling with observational corrections and accounts for local wind effects like topography and land cover to estimate maximum 0.2-second wind gusts at 10 meters above ground. This release aims to showcase a method for producing local TC wind fields to support post-disaster surveys and vulnerability modeling.

Use Cases

• Validate wind field modeling outputs based on observational data from mobile anemometers mentioned in the description.
• Estimate maximum wind gust speeds for damage assessment based on the corrected wind field data.
• Develop fit-for-purpose land cover datasets for hazard modeling based on the use of Landsat archives described.
• Refine vulnerability models for housing stock based on combined wind field and damage survey data.

Strengths

• Focuses on a specific, severe tropical cyclone event (Tropical Cyclone Debbie, March 25–29, 2017).
• Integrates multiple data sources: modeling, observations, and corrections for topography, land cover, and shielding.
• Aims to provide a best estimate of actual wind speeds where observational coverage is sparse.

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 and temporal bias inherent to a single cyclone event.
