FIREX-AQ: NOAA Twin Otter Meteorological and Navigational Data from 2019 Wildfire Campaign

FIREX-AQ was a major 2019 NOAA/NASA campaign studying North American fire emissions. This dataset contains in situ meteorological and navigational data collected via GPS and probes onboard the NOAA-CHEM Twin Otter aircraft, focusing on nighttime plume chemistry. Data collection is complete and archived at the NASA Atmospheric Science Data Center.

Use Cases

• Modeling plume rise and dispersion based on in situ meteorological measurements.
• Analyzing chemical processing in lofted wildfire plumes based on the nighttime sampling focus.
• Studying local weather impacts at fire boundaries based on the described measurement goals.
• Validating satellite-derived fire data (e.g., temperature, plume height) with aircraft in situ observations.

Strengths

• Data collection is explicitly stated as complete.
• Part of a large interagency campaign (FIREX-AQ) utilizing multiple aircraft and ground stations.
• Archived at the authoritative NASA Atmospheric Science Data Center (ASDC).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• File formats include BIN and ISO, which may require specialized tools for access.
