Marginal fire spread in live fuel beds - horizontal fuels

This data publication contains data from 240 laboratory fire spread experiments in high bulk density fuel beds of live chaparral vegetation from the North Mountain Experimental Area in California, carried out between 2003 and 2006. Fuels consisted of branches and foliage from Adenostoma fasciculatum (chamise), Ceanothus crassifolius (ceanothus), Arctostaphylos glandulosa (manzanita), and Quercus berberidifolia (scrub oak). Laboratory environmental conditions, fuel bed characteristics, wind and slope values, and fire behavior data including spread success, rate of spread, flame length, and flame angle are included. Fortran code used to estimate fire behavior with FIRECAST and code to calculate rate of spread in live fuel beds is also included.The objective of the study was to examine the influence of a variety of fuel and environmental variables on fire spread success in homogeneous fuel beds composed of foliage and branch material from major chaparral shrub species.This package was originally published on 01/29/2015. On 09/21/2015, the data were updated to include measurements that were previously missing because the videos for these fires had not yet been analyzed for the flame data. A few missing rate of spread measurements were also added - it was just an oversight they were not included in the first version of the data. Here are the data measurements that have been added: Fire 240: Col K added (Rate of spread); Fire 242: Col K, O-T added (Rate of spread, Flame length, Flame Length s.d., Flame depth, Flame depth s.d., Flame angle, Flame angle s.d.); Fire 243: Col O-T added Flame length, Flame Length s.d., Flame depth, Flame depth s.d., Flame angle, Flame angle s.d.); and Fire 246 Col K, O-T added (Rate of spread, Flame length, Flame Length s.d., Flame depth, Flame depth s.d., Flame angle, Flame angle s.d.). On 03/23/2016 this data package was updated to include Fortran code used to esimate fire behavior with FIRECAST and code to calculate rate of spread in live fuel beds. Minor metadata updates were made on 12/15/2016. Additional metadata updates were made on 03/19/2026, including the addition of a new reference, email address updates, and other minor updates. The metadata included in the \Supplements folder were also updated with similar changes, to bring the content up to date. For additional information about these data, see Weise et al. (2016).
