Scientists know that variable weather conditions have a dramatic influence on fire behavior and fire effects, but the influence of weather can be difficult to evaluate because current fire progression maps, which chart the perimeter of an actively burning fire, are rarely mapped on a daily basis. As such, it is difficult to associate weather with observed fire behavior or effects because it is not always known what day any given area has burned. Scientists with the Aldo Leopold Wilderness Research Institute developed a new technique using an existing remotely sensed dataset to map the daily progression of fires. This technique provides new opportunities for studying the influence of weather on fire behavior and fire effects. The methods developed by these scientists provide a viable option for producing day-of-burning data where agency-generated fire progression maps are of poor quality or unavailable. Used in conjunction with data from weather stations, this method will help researchers from varied disciplines to evaluate the influence of observed daily weather on observed fire-related effects (e.g., smoke productions, carbon emissions, and burn severity) over large landscapes and over large numbers of fires. In fact, this method has already been successfully incorporated into other fire studies, including one that quantified the influence of weather on fire spread.
