Plain Language Summary

Understanding wildfire rate of spread (RoS) is often a key objective of many fire behavior modelling and measurement exercises. In this paper, we used instrumented moderate scale open-air laboratory burns to provide an assessment of eight different methods of flame front RoS determination, including visible imagery (VIS) analysis techniques, use of thermocouple arrays, and four thermal infrared (IR) image analysis approaches. We are able to (1) determine how measurement approach influences derived RoS, and (2) recommend the best method of the techniques used to map RoS. Results suggest that derived RoS is significantly influenced by the measurement approach, and we are able to identify one of the thermal infrared imaging methods as the most appropriate for providing rate and direction of spread at these scales of measurement.
