Antarctic Circumnavigation Expedition Wind Velocity Data, 2016-2017

The Antarctic Circumnavigation Expedition (ACE) 2016/2017 collected one-minute average horizontal wind velocity data from legs 0 to 4. The data has been filtered for spurious observations and true wind correction was redone using quality-checked ship track velocity. This dataset, authored by Sebastian Landwehr of École Polytechnique Fédérale de Lausanne, is available under a Creative Commons Attribution 4.0 International License.

Use Cases

• Analyzing temporal wind patterns in the Southern Ocean based on one-minute averaged observations.
• Studying the effects of ship superstructure on airflow measurements based on the uncorrected data status.
• Comparing corrected versus uncorrected wind data for methodological research based on the description of flow-distortion.
• Investigating wind conditions during specific legs of a major Antarctic expedition based on the leg-based data segmentation.

Strengths

• Data has undergone filtering for spurious observations, indicating a quality control step.
• True wind correction was recalculated using quality-checked ship track velocity data.
• Dataset explicitly states its uncorrected status for airflow distortion, providing clarity for appropriate use cases.

Limitations

• Data has not been corrected for air-flow distortion caused by the ship's super structure, limiting its use for studies requiring actual true wind speed.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file size, and last update date are unknown, which may limit suitability assessment.
