Chaparral shrub bulk density and fire behavior

This data publication contains bulk density measurements from two typical species of chaparral shrub which were harvested in 2010 from the North Mountain Experimental Area near Riverside, CA (NMEA), namely chamise (Adenostoma fasciculatum) and manzanita (Arctostaphylos sp.). Data include shrub height, crown length, crown width, crown base height, and moisture content, as well as total mass, mass by fuel particle size class, crown volume, and calculated bulk density by shrub height segments. Also included are fire characteristics data from a companion study of fire behavior in similar individual 4-year old live chamise shrubs. The fire behavior data include shrub bulk density, moisture content and total mass consumed during each experimental run for multiple bulk density classes, wind speeds, and ignition methods. Burn time, horizontal and vertical flame spread rates, flame length and flame angle, as well as maximum mass loss rate and peak gas temperatures were also recorded. The R code used to analyze these fire characteristics in Li et al. 2016 is also included.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

本数据集收录了2010年自加利福尼亚州里弗赛德市附近北山实验区（NMEA）采集的两种典型灌木物种的体积密度测量数据，分别为灌木状腺叶（Adenostoma fasciculatum）和山棘（Arctostaphylos sp.）。数据涵盖了灌木高度、树冠长度、树冠宽度、树冠基高度以及含水量，还包括总质量、按燃料颗粒大小分类的质量、树冠体积以及按灌木高度段计算的体积密度。此外，还包括了针对类似四年生灌木状腺叶个体火灾行为的伴随研究中的火灾特性数据。火灾行为数据包括灌木体积密度、含水量和每个实验运行期间消耗的总质量，针对多个体积密度等级，风速和点火方法。同时记录了燃烧时间、水平及垂直火焰蔓延速率、火焰长度和火焰角度，以及最大质量损失速率和峰值气体温度。此外，还包括了用于分析这些火灾特性的 Li 等人于 2016 年发表的 R 代码。此记录来源于美国农业部企业数据清单，该清单为 https://data.gov 目录提供数据。本记录的数据资源包括以下内容：ISO-19139 元数据、ArcGIS Hub 数据集和 ArcGIS GeoService。欲获取详细信息，请访问 https://data.gov。
