The Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE) was designed to collect atmospheric, fuels, fire behavior, energy balance, emissions, and fire effects data to evaluate and advance fire models and further our understanding of fire science questions. This data publication contains fuel loading, fuel consumption, and fuel moisture content data for 28 sample units associated with 6 small replicate grass fires, 2 large operational grass fires, and 8 large operational forested fires conducted during 2008, 2011, and 2012 in longleaf pine (Pinus palustrus) ecosystems of the southeastern USA. The small replicate grass fires burned in 2012 were named S3, S4, S5, S7, S8, and S9. The two operational grass fires were named L1G (2012) and L2G (2012) and were burned in 2012. The 8 operational forested units were named Dubignon East, North Boundary, Turkey Woods, 307B, and 608A (burned in 2008), 608A and 703 C (burned in 2011), and L2F (burned in 2012). Pre- and post-fire loadings by fuelbed component in all 28 units were collected using a combination of line intersect inventory and clip plot methods. Fuel consumption was determined by subtracting the pre- and post-fire values. Fuel moisture samples were collected, weighed and oven dried to determine fuel moisture content by fuelbed component immediately prior to ignition. This data publication also contains turkey oak fuel loading data collected in 2012 near L2G, S7, and S8, in order to assist the calibration of terrestrial LiDAR.
