Videos and processed results from laboratory and field studies of firebrand generation from branches and sticks

These data were collected as part of a project funded by the Joint Fire Science Program (Grant 15-1-04-9). The objective of the project was to identify what physical conditions have the greatest influence on the generation of embers (also known as firebrands). The efforts consisted of experiments at both laboratory (i.e., branch-scale) and outdoor (i.e., tree-scale) studies. This data publication contains the data collected for the former study which took place from 2015-2019. This includes all screening study videos, detailed information on testing conditions and other notes for each test, as well as time to generation data and the associated experimental conditions. Additionally, the R code used to run the associated factorial analysis, data files used to run that code, and the MATLAB scripts used to plot the results are provided.These data were collected in an effort to identify which factors have the greatest influence on generation behavior of firebrand at branch-scales.For more information about this study and these data, see Hudson (2018).本数据集采集自联合火灾科学计划（Joint Fire Science Program）资助的研究项目（拨款编号：Grant 15-1-04-9）。该项目的研究目标为明确哪些物理条件对余烬（firebrand，又称飞火火种）的生成影响最为显著。本次研究包含实验室尺度（即分支尺度）与野外尺度（即树木尺度）两类实验。本数据集收录了2015至2019年间开展的实验室尺度研究的全部相关数据，涵盖所有筛选实验的视频记录、每项测试的详细试验条件及配套备注、火种生成时间数据与对应实验环境参数。此外，本数据集还提供了用于执行相关因子分析的R代码、运行该分析所需的数据文件，以及用于绘制实验结果的MATLAB脚本。本数据集的采集旨在明确分支尺度下影响飞火火种生成行为的核心影响因素。如需了解本研究与本数据集的更多细节，请参阅Hudson（2018）。
