Direct experimental measurements of the energy, fluid flow, and chemical processes occurring in full-scale wildland fires over a spatial extent are difficult to obtain. Techniques exist to measure the radiant intensity or emissive power of the flame; however, the high temperature and transient nature of naturally burning wildland fires has been limited to just a few localized measurements of fire intensity (Butler et al. 2004). Recent advances in unmanned aerial systems (UAS) and light weight, high resolution sensors provide an opportunity to address the various limitations associated with previous research in landscape scale fire radiative power (FRP) estimates. A series of nine small scale (0.5-1km2) field experiments were instrumented with multiple horizontal and nadir view fire behavior packages (FBPs) in order to characterize point source fire energy measurements. Additionally, in-situ and remote sensed (UAS) radiometric thermograhy data with collocated at high resolution in space and time. Coordinates of each in-situ location were acquired and pre-loaded into the UAS flight plan to ensure collocation data collects. This paper presents the experimental design and preliminary results with the intent to develop a strong correlation between highly resolved ground based fire energy measurements collacted with UAS remote sensed thermography. | URI: | https://hdl.handle.net/10316.2/44666 | ISBN: | 978-989-26-16-506 (PDF) | DOI: | 10.14195/978-989-26-16-506_149 | Rights: | open access |
