FIREX-AQ: NOAA-CHEM Twin Otter In Situ Aerosol Data from 2019 Wildfires

FIREX-AQ_Aerosol_AircraftInSitu_N48_Data contains in situ aerosol measurements from the NOAA-CHEM Twin Otter aircraft during the 2019 FIREX-AQ campaign. The data, collected by UHSAS, AMS, CLAP, and PILS instruments, focuses on nighttime plume chemistry from Western wildfires. This product is part of a NOAA/NASA interagency study to understand the impact of fire emissions on tropospheric chemistry and air quality.

Use Cases

• Modeling aerosol microphysical properties in wildfire plumes based on UHSAS instrument data
• Analyzing aerosol chemical composition from organic and sulfate particles based on AMS and PILS measurements
• Studying nighttime chemical processing in lofted fire plumes based on the NOAA-CHEM Twin Otter's mission focus
• Assessing satellite capabilities for fire detection by comparing in-situ aerosol data with satellite analog measurements

Strengths

• Data collection is complete, as stated in the description
• Part of a major interagency campaign (FIREX-AQ) utilizing multiple aircraft and ground stations
• Includes measurements from four specialized instruments (UHSAS, AMS, CLAP, PILS)

Limitations

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