Videos, images, and processed results from laboratory and field studies of firebrand generation from trees

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 latter study which took place from 2015-2019. This study included the evaluation of Douglas-fir (Pseudotsuga menziesii), grand fir (Abies grandis), western juniper (Juniperus occidentalis) and ponderosa pine (Pinus ponderosa) trees. Embers were collected on an array of fire-resistant fabric panels and trays filled with water. This includes images of all embers collected during testing and fabric with char marks after testing as well as the tabular data containing all testing condition information. Videos of the experiment are included. Additionally, the R code used to run the linear regression analysis, data files used to run that code, and the MATLAB scripts used to perform other calculations and 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 tree-scales.
