BOREAS Twin Otter Aircraft Flux and Meteorological Data

BOREAS AFM-04 team collected airborne flux and meteorological data using an NRC Twin Otter aircraft. Measurements include fluxes of sensible heat, latent heat, momentum, ozone, methane, and carbon dioxide, plus supporting parameters like temperature, humidity, wind, and radiometric observations. Data were gathered in 1994 and 1996 over the Northern and Southern Study Areas of the BOREAS project.

Use Cases

• Analyzing surface-atmosphere exchange of greenhouse gases like methane and carbon dioxide using flux columns.
• Studying boundary layer dynamics and energy balance with sensible heat, latent heat, and momentum flux measurements.
• Correlating atmospheric conditions with surface properties using radiometric observations like greenness index and surface temperature.
• Investigating spatial and temporal patterns of ozone concentrations in a boreal forest environment.
• Validating remote sensing products or land surface models with in-situ meteorological data including temperature, humidity, and wind speed/direction.

Strengths

• Data collection spans multiple years, covering three Intensive Field Campaigns in 1994 and additional flights in July and August 1996.
• Includes a diverse set of measurements: multiple gas fluxes, core meteorological parameters, aircraft state, and radiometric data.
• Cross-platform presence on NASA EarthData and Data.gov signals its recognized importance for earth science research.

Limitations

• Critical metadata such as row count, file size, and a complete column list are unavailable from all sources.
• Sources conflict on the 'last updated' date, reporting both 1994-09-19 and 2026-03 13.
