CARVE Arctic Aircraft Wind Speed and Direction Data 2015

CARVE L1 Daily Flight Path and Winds Data provides high-frequency wind speed and direction measurements from the C-23 Sherpa aircraft over the Alaskan and Canadian Arctic. Data were collected in situ at 1-second intervals during 2015 airborne campaigns using an Aventech AIMMS-30 Airborne Wind Sensor. This dataset is managed by ORNL_CLOUD and is designed for integration with other CARVE airborne instrument data.

Use Cases

• Analyzing high-frequency wind speed and direction patterns over the Arctic during 2015 flight campaigns.
• Integrating wind data with concurrent scientific measurements from other CARVE airborne instruments for multi-variable atmospheric studies.
• Studying flight-level wind dynamics to understand their influence on Arctic carbon flux and reservoir vulnerability.
• Validating or calibrating regional climate models using precise, in-situ wind observations from a specific aircraft and sensor.

Strengths

• Data provides high temporal resolution with measurements recorded at 1-second intervals throughout each flight.
• Collection uses a specific, documented sensor (Aventech AIMMS-30 Airborne Wind Sensor) for in-situ measurement.
• Dataset has cross-platform presence on NASA EarthData and Data.gov, indicating recognized importance and curation.

Limitations

• Key metadata conflicts exist: the last updated date is reported as both 2015-11-13 and 2026-03 13 across sources.
• Core descriptive attributes like row count, file size, and specific column names are unavailable from all provided sources.
• Data coverage is limited to flights conducted only during the year 2015.
