AbstractWith record-breaking disastrous wildfires along with the human toll fighting them, no real-time technology is available to hot shots or heli-tanker suppression crews to easily detect and pinpoint water/retardant suppression on latent or lingering hot spots which are often obscured by dirt, smoke or dust. We propose to generate functional requirements of a microwave radiometer handheld sensor and airborne sensor, develop a brightness temperature radiative model to investigate the microwave thermal emission characteristics from below surface hot spots as a function of operation frequency, conduct outdoor radiometer measurements of burning materials to aid in validating the model, and develop a preliminary design for a handheld and/or microwave airborne sensor. Initially, we will leverage/use a CME/Raytheon developed passive microwave radiometer to conduct brightness temperature measurements of certain forest fuel sources to support the selection of an optimum detector frequency. Military-related microwave technology advancements enable the feasibility of developing small airborne, ground-based, and even handheld microwave sensors. Even in heavy smoke, a handheld, passive microwave sensor would allow hotshot supervisors to prioritize suppression crews to the most threatening sites. A helicopter-mounted sensor would allow pinpoint drop of their precious suppression cargo; and hot shot crews could easily detect sursurface roots still burning but hidden. Our team proposes a multi-pronged approach to significantly improve the performance and safety of wildfire suppression crews.
