FIREX-AQ: NOAA-CHEM Twin Otter Smoke Age Analysis Data

FIREX-AQ_Analysis_N48_Data are supplementary smoke age data derived from models including NAM, GFS, and HRRR, corresponding to the NOAA-CHEM Twin Otter aircraft. The data was collected during the summer 2019 FIREX-AQ campaign, a NOAA/NASA interagency study of North American fires. The campaign utilized instrumented airplanes, satellites, and ground-based stations to measure fire emissions and their impact on tropospheric chemistry and air quality.

Use Cases

• Modeling smoke age and transport based on derived model data from NAM, GFS, and HRRR.
• Studying nighttime plume chemistry based on the NOAA-CHEM Twin Otter's focus.
• Analyzing the integrated impact of fire emissions on tropospheric chemistry and composition as described in the campaign goal.
• Assessing satellite capability for fire detection and emission estimation as mentioned in the FIREX-AQ objectives.

Strengths

• Data collection is described as complete.
• Campaign involved multiple platforms including 23 DC-8 science flights and 11 ER 2 flights.
• Derived from operational weather models (NAM, GFS, HRRR).

Limitations

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