FIREX-AQ: Aircraft In-Situ Photolysis Rate Measurements from 2019 Wildfire Campaign

23 science flights were completed by the NASA DC-8 aircraft during the summer 2019 FIREX-AQ campaign. This dataset contains in-situ photolysis rate (J-value) measurements from the CAFS instrument onboard the DC-8, part of a larger NOAA/NASA study of North American fire emissions. The campaign aimed to understand the impact of fire emissions on tropospheric chemistry and air quality.

Use Cases

• Modeling photochemical reaction rates in wildfire plumes based on in-situ J-value measurements.
• Analyzing the relationship between fire conditions and trace gas emissions based on detailed plume sampling.
• Assessing satellite capabilities for fire detection by comparing with high-detail aircraft measurements.
• Studying chemical transformation of pollutants downwind of fires based on the campaign's focus.

Strengths

• Data collection is complete for this product.
• Part of a major interagency campaign (FIREX-AQ) with coordinated aircraft, satellite, and ground-based measurements.
• DC-8 payload was capable of measuring over 200 trace gas species and aerosol properties.

Limitations

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