ACE 2016/2017: One-Minute Average Horizontal Wind Velocity from Antarctic Circumnavigation

Antarctic Circumnavigation Expedition data provides one-minute average horizontal wind velocity measurements from legs 0 to 4 of the 2016/2017 voyage. The data has been filtered for spurious observations and corrected for air-flow distortion caused by the ship's superstructure. Sebastian Landwehr from École Polytechnique Fédérale de Lausanne prepared the dataset, which is available under a CC BY 4.0 license.

Use Cases

• Modeling Southern Ocean wind fields based on corrected ship-based observations.
• Analyzing high-frequency wind variability during the Antarctic summer season.
• Validating satellite-derived wind products against quality-controlled in-situ measurements.
• Studying air-flow distortion effects on meteorological measurements from research vessels.

Strengths

• Data has been corrected for air-flow distortion, a known source of error for ship-based measurements.
• Observations have been filtered for spurious data points, suggesting quality control.
• True wind correction was redone using quality-checked ship track velocity data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
