1986 Annaburroo Experimental Grassland Fire Data

In 1986 CSIRO conducted a very large series of fire experiments in grasslands at Annaburroo Station in the Northern Territory. This work was supported by a number of rural fire authorities with the objective of quantifying the effect of fuel load on the behaviour and spread of free-burning grass fires. This collection collates the data collected from this experimental series which were used to develop the CSIRO Grassland Fire Spread Model published in 1998. Data include measurements and observations of fuel, weather and fire behaviour \nLineage: 121 experimental fires were conducted in grasslands of Annaburroo station. Two grass species were present on the site: Themeda and Eriachne. Plots were created that ranged in size from 100 m by 100 m to 300 m by 300 m. Prior to experimentation, grass on each plot was modified to produce one of three treatments--grass left modified (control), grass was mown and cuttings retained, and grass was mown and cuttings removed. Fuel attributes for each plot were measured across multiple transects; these included fuel height, fuel load, curing state. Four anemometers were placed on the corners of each plot and fires ignited on the upwind edge. Fire behaviour was observed on the ground and photographs of fire progression taken from a helicopter producing oblique view at regular intervals of fire spread.

1986年，澳大利亚联邦科学与工业研究组织（CSIRO）在北领地安娜伯鲁站（Annaburroo Station）的草原区域开展了大规模系列火烧实验。本研究得到多家乡村消防主管部门的支持，核心目标为量化燃料载荷对自由燃烧草原火灾的行为特征与蔓延规律的影响。本数据集汇编了本次系列实验采集的全部数据，这些数据被用于开发1998年发布的《CSIRO草原火灾蔓延模型》。数据集涵盖燃料、气象及火灾行为的测量与观测数据。
数据集谱系：本次实验共在安娜伯鲁站的草原区域开展121次火烧实验。实验场地内存在两种草本植物：Themeda与Eriachne。实验样地尺寸范围为100米×100米至300米×300米。实验开展前，工作人员对每个样地的草本植被实施三种处理之一：保留原生植被（对照组）、刈割后保留残茬、刈割后移除残茬。随后通过多条样带对每个样地的燃料属性进行测量，测量指标包括燃料高度、燃料载荷以及燃料熟化度。在每个样地的四角安装4台风速仪，并在样地上风边缘点火。火灾行为通过地面观测以及直升机定期拍摄的斜射视角火场蔓延照片进行记录。
