Platform: NASA DC-8 Payload
The NASA DC-8 instrument payload is specifically tailored to the FIREX-AQ science questions and will provide the most detailed characterization of fire plumes from any aircraft platform to date. The NASA DC-8 will have gas- and aerosol-phase measurements as well as remote sensing capabilities. Many of the in-situ measurements will have improved time resolution; up to 10 Hz for some instruments. When sampling small fires, plume penetrations as short as 5 seconds are expected and the value of sampling with a sub-second time resolution has been demonstrated by research in 2016.
