An integrated, comprehensive, quality-assured data set helps develop, validate, and evaluate the next generation of fire and smoke models. Beginning in 2008, a group of scientists pooled resources and fire and fuels data on prescribed fires in the southeastern United States. This effort was called the Prescribed Fire and Combustion and Atmospheric Dynamics Research Experiment (RxCADRE). In 2012, the Joint Fire Science Program provided funds to improve and continue the RxCADRE effort, focusing on integrated, fine-scale and operational-scale scientific measurements within six identified core fire science disciplines including: fuels, meteorology, surface fire behavior, event-scale fire mapping, smoke, and fire effects. To date, the RxCADRE collection includes integrated datasets on 20 burns ranging in scale from 1.5 to 1,500 hectares (3.7 to 3,707 acres), providing a high quality, integrated fire data set used for many research activities, including fire growth and emissions model testing and evaluation. The data from RxCADRE provides the fire modeling community with information necessary to develop, validate, and evaluate next generation fire and smoke models. Improved models and model results provide resource managers with information to inform decisions regarding both wildland and prescribed fire. Data gathered also provides valuable information on fire activity in a variety of fuel types. Findings from this effort help to develop improved guidelines for firefighter safety zones, improve fire growth modeling, and link remote sensed data to fire energy release.
