Th e Rx-CADRE project was the combination of local and national fire expertise in the field of core fire research. The project brought together approximately 30 fire scientists from six geographic regions and seven diff erent agencies. Th e project objectives were to demonstrate the capacity for collaborative research by bringing together individuals and teams with a wide range of fire monitoring expertise and equipment from across the United States and Canada in order to instrument prescribed burns in the southeastern United States. A concurrent workshop was organized that brought fire and fire eff ects modelers into the mix, creating the linkage between data generation and data use for fire and fire eff ects model validation and development. The group documented fire–atmospheric dynamics on prescribed fires in southern pine (Pinus palustris) woodlands of varying size, ranging from 10 to 1,000 ha. Specifically, we 1) compared in situ and remote-sensed heat environments of prescribed burns, 2) documented coupled atmospheric interactions, 3) produced validation data sets for coupled fire– atmospheric dynamic models, and 4) related fire behavior to first-order fire effects. On the fully instrumented fires, the group collected data on pre-burn fuel loads, post-burn consumption, ambient weather, in situ convective dynamics, plume dynamics, radiant heat release (both from in situ and remote sensors), in situ fire behavior, and select fire effects.
