CAMEX-4 DC-8 Aircraft Meteorological Measurement System Data

Meteorological data was collected by the DC-8 aircraft's Meteorological Measurement System during the CAMEX-4 field campaign to study atmospheric temperature properties. The system integrates air-motion and aircraft-motion sensing to measure air velocity relative to the aircraft and the Earth. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyzing upper-air atmospheric temperature profiles using measured total temperature.
• Studying atmospheric pressure dynamics via static pressure and total pressure measurements.
• Calculating wind vectors and airspeed by combining air velocity and aircraft ground speed data.
• Investigating hurricane structure and evolution using in-situ meteorological observations from the CAMEX-4 campaign.

Strengths

• Data originates from a controlled NASA aircraft instrument system designed for precise meteorological measurement.
• Includes specific measurements for key atmospheric variables like temperature, pressure, and air velocity.
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance and curation.

Limitations

• Key quantitative details like row count, file size, and specific temporal coverage are unavailable from all sources.
• A significant conflict exists between the last updated dates: Data.gov lists 2026-03 13 (future date), while NASA EarthData lists 2001-09-25.
• The complete set of data columns is not explicitly listed, limiting precise understanding of the data structure.
