ACLOUD 2017: High-Resolution Aircraft Measurements of Arctic Wind and Temperature

May/June 2017 data from the ACLOUD campaign, measuring meteorological parameters at 100 Hz frequency from two aircraft. The dataset, authored by Jörg Hartmann, contains time-stamped, geolocated measurements of temperature, three wind components, pressure, and aircraft attitude for flights based in Longyearbyen, Svalbard. Data processing and accuracy details are provided in referenced publications.

Use Cases

• Deriving turbulent fluxes of momentum and sensible heat based on high-frequency wind and temperature data during straight and level flight sections.
• Analyzing spatial patterns of atmospheric conditions in the Arctic based on geolocated time-series measurements along flight tracks.
• Validating or improving numerical weather and climate models based on high-resolution in-situ observations of wind components and temperature.
• Studying aircraft-influenced measurement corrections and accuracy based on provided pitch, roll, and heading angles.

Strengths

• High temporal resolution of 100 Hz for wind and temperature measurements.
• Absolute accuracy of wind components reported as 0.2 m/s for straight and level flight sections.
• Data includes precise geolocation (latitude, longitude, height) and aircraft attitude (pitch, roll, heading) for context.
• Campaign and data processing are documented in peer-reviewed publications with provided DOIs.

Limitations

• Wind measurement validity and full accuracy are limited to in-flight conditions, specifically straight and level flight sections.
• Row count, file formats, and license information are unknown from the provided metadata.
• Column-level documentation is absent from the input; field semantics must be inferred from the description after download.
