Overview

Measuring fire passage in a longleaf pine forest from a boom lift, 2012 RxCADRE, GeorgiaThe availability of integrated, quality-assured fuels, atmospheric, fire behavior, energy, smoke, and effects data are limited and hinders our ability to evaluate fire models and tackle fundamental fire science questions.  To help fill this void, the Core Fire Science Caucus—an ad hoc group of 30 scientists that met periodically to discuss fire behavior research, identify knowledge gaps, and outline a strategic direction for continued research—pooled their operational and in-kind resources and collaboratively instrumented and collected fire data on seven operational prescribed fires in 2008 and 2011 at Eglin Air Force Base in Florida and the Joseph W. Jones Ecological Research Center in Georgia. This effort was termed the Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE). The project enabled scientists to integrate processes for collecting complementary research data across fire-related disciplines before, during, and after the active burning periods of prescribed fires.  The goal was to develop synergies between the fuel, atmospheric conditions, fire behavior, radiative energy, smoke generation, and fire effects measurements for fire model development and evaluation.

Introduction
Measuring air quality in Florida RxCADRE BurnIn 2012, the Joint Fire Science Program (JFSP) funded a continuation and expansion of this effort to include 6 small replicate and 3 operational prescribed burn blocks in longleaf pine ecosystems on Eglin Air Force Base in northern Florida. The support included data collection for RxCADRE 2012, data reduction and analysis for the 2008, 2011 and 2012 RxCADRE projects, a design of a data management system and the upload of the data into a permanent data repository for all to access.  Nearly 30 scientists and technicians participated in the 2008 and 2011 campaigns while over 90 scientists and technicians participated in the 2012 campaign. Eglin Air Force Base was selected for the much larger 2012 RxCADRE project because of excellent management support in previous efforts, appropriate research sites, high probability experimental fires would occur, controlled air space for deployment of Remotely Piloted Aircraft Systems (RPAS), and data acquisition and processing support.  

The RxCADRE project organized its data collection around a stepwise, hierarchical structure with 6 major data discipline areas (fuels, meteorology, fire behavior, energy balance, emissions, and fire effects) and associated variables. The burn unit selection targeted simple grass, grass/shrub, and managed southern pine forest fuelbeds at both fine- and operational scales. Each discipline employed a series of data collection techniques ranging from simple clipping and weighing fuels for mass to mapping fire progression with manned and unmanned aircraft. Once collected, data was reviewed, reduced, analyzed and linked to a descriptive set of metadata. The data package was uploaded to a globally accessible repository maintained by the US Forest Service in Fort Collins, CO.  The data is organized by discipline areas and has a table of contents with linkages to the specific data locations.
