ACTIVATE Falcon: In Situ Trace Gas Measurements over the Western Atlantic

ACTIVATE_TraceGas_AircraftInSitu_Falcon_Data contains trace gas measurements collected onboard an HU-25 Falcon aircraft during the NASA ACTIVATE project. The ACTIVATE campaign was a five-year Earth-Venture Sub-Orbital field campaign that conducted 150 coordinated flights over the western North Atlantic from 2020 to 2022. The project aimed to provide globally-relevant data about marine boundary layer cloud systems, atmospheric aerosols, and climate feedbacks.

Use Cases

• Classifying airmass types based on pollution trace gas measurements.
• Analyzing aerosol-cloud-meteorology interactions based on coordinated aircraft sampling.
• Studying the role of marine boundary layer clouds in Earth's energy balance based on atmospheric state data.
• Characterizing the shallow cumulus cloud regime based on statistical survey flight patterns.

Strengths

• Data originates from a 5-year NASA Earth-Venture Sub-Orbital field campaign.
• Collection includes 150 coordinated flights over a broad range of conditions.
• Sampling strategy targeted both statistical surveys and process studies for robust characterization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
