Post-wildfire flooding and debris flows pose a threat to ecosystems and infrastructure. As the frequency and size of severe wildfires increase, there is a growing need for predictive debris flow hazard modeling in unburned but fire-prone landscapes. However, no crosswalks have been established between physics-based models of fire behavior and the remotely sensed burn severity inputs needed for debris flow modeling. Here, we explore this connection by creating a large ensemble of fire behavior simulations using QUIC-Fire – a fast-running three-dimensional fire model – in basins across five major-disaster wildfires in California and Washington. This data release child item includes: 1) QUIC-Fire simulation outputs summarized vertically across the simulation domain, 2) QUIC-Fire simulation outputs for four simulations used to replace malfunctioning QUIC-Fire simulations; summarize vertically across the simulation domain, 3) QUIC-Fire simulation outputs (including corrected simulations) summarized horizontally and vertically across the simulation domain.
