BOREAS Aircraft Sounding Data for Carbon Dioxide and Ozone

Northern and Southern Study Areas in Canada's BOREAS project contain atmospheric sounding measurements from 1994 and 1996. The NRC Twin Otter aircraft captured vertical profiles of carbon dioxide, ozone, temperature, pressure, humidity, and wind data through the boundary layer. This dataset is produced by the National Aeronautics and Space Administration.

Use Cases

• Analyzing vertical profiles of carbon dioxide and ozone concentrations in the boreal forest boundary layer.
• Studying relationships between atmospheric pressure, dry bulb temperature, and dewpoint temperature with altitude.
• Calculating atmospheric stability using potential temperature and mixing ratio data.
• Investigating wind speed and direction patterns at different altitudes over the study areas.
• Correlating aircraft position, heading, and altitude data with concurrent surface measurements from the BOREAS campaign.

Strengths

• Data collection covers two field seasons (1994 and 1996) for temporal comparison.
• Measurements include multiple co-located atmospheric variables (CO2, O3, temperature, pressure, wind) for integrated analysis.
• Coverage includes both the Northern and Southern Study Areas (NSA and SSA) for spatial context.

Limitations

• Critical metadata conflicts exist: row count, file size, and specific license terms are unknown across all platforms.
• The dataset's age (last measurements in 1996) limits analysis of recent atmospheric trends.
• Column names and precise data structure are not provided, complicating direct usage.
