Visualizing Uncertainties in Ensemble Wildfire Forecast Simulations

Wildfires pose substantial risks to our health, environment, and economy. Studying wildfires is challenging due to their complex interaction with the atmosphere dynamics and the terrain. Researchers have employed ensemble simulations to study the relationship among variables and mitigate uncertainties in unpredictable initial conditions. However, many wildfire researchers are unaware of the advanced visualization available for conveying uncertainty. We designed and implemented an interactive visualization system for studying the uncertainties of fire spread patterns utilizing band-depth-based order statistics and contour boxplots. We also augment the visualization system with the summary of changes in the burned area and fuel content to help scientists identify interesting temporal events. In this paper, we demonstrate how our system can support wildfire experts in studying fire spread patterns, identifying outlier simulations, and navigating to interesting times based on a summary of events.
