New Jersey fuel treatment effects: 3-dimensional turbulence and temperature data

This data publication contains environment data collected as part of a Joint Fire Science Program project designed to collect landscape-scale fuels data before and after prescribed fires to quantify consumption, collect data for the parameterization and evaluation of computational flow-dynamics models for simulating fire behavior, and synthesize data for the evaluation of fuels treatment effectiveness. The data include 3-dimensional turbulence and temperature data from overstory towers in the New Jersey Pinelands (Burlington and Ocean Counties), measuring the fire environment within three separate fire experiments, Ex1, Ex2, and Ex3. These experiments were performed in 2013, 2014 and 2015, respectively. For each experiment, a control tower was constructed outside of the fire area and three towers inside of the fire area. Each of the intra-fire towers and the control tower were instrumented identically with an overstory sonic anemometer and a thermocouple array to sense the fire environment. The control tower also collected standard meteorological variables such as windspeed/direction, relative humidity, air temperature, and 10-hour fuel moisture.The data provided here were collected as part of the Joint Fire Science funded project: “Evaluation and Optimization of Fuel Treatment Effectiveness with an Integrated Experimental/Modeling Approach.” From 2001-2011, approximately US $5.6 billion was spent on hazardous fuel reduction to treat an average of approximately 2.5 million acres per year across the United States. Because of the cost and complexity involved, there is a need for implementing treatments in such a way that hazard mitigation, or other management objectives, are optimized. Our work integrated extensive forest census measurements, remote sensing methodologies, three highly-instrumented fuel reduction treatments, and numeric modeling of fire spread to test the principals and physics behind fuel reduction treatments. These datasets provide measurements for the evaluation of fuel treatment effects and effectiveness.Original publication date was 11/14/2017. Minor metadata updates were made on 11/17/2022.

本数据发布包含作为联合火灾科学计划项目一部分收集的环境数据，该计划旨在在规定火烧前后收集景观尺度燃料数据，以量化消耗，收集用于参数化和评估模拟火行为计算流体动力学模型的参数数据，并综合数据以评估燃料处理效果。数据包括来自新泽西松树林（伯灵顿县和海洋县）林冠塔的3维湍流和温度数据，测量了三个独立火实验（Ex1、Ex2和Ex3）中的火环境。这些实验分别在2013年、2014年和2015年进行。对于每个实验，均在火区外建造了一个控制塔，并在火区内建造了三个塔。每个火区内塔和控制塔均以相同的林冠风速计和热电偶阵列进行了仪器配备，以感知火环境。控制塔还收集了标准气象变量，如风速/风向、相对湿度、空气温度和10小时燃料含水量。这些数据作为联合火灾科学资助项目“综合实验/建模方法评估和优化燃料处理效果”的一部分收集。从2001年到2011年，美国大约花费了约56亿美元用于危险燃料减少，平均每年处理约250万英亩。鉴于成本和复杂性，有必要以优化灾害缓解或其他管理目标的方式实施处理。我们的工作整合了广泛的森林普查测量、遥感方法、三次高度仪器化的燃料减少处理以及火灾蔓延的数值模拟，以测试燃料减少处理背后的原理和物理。这些数据集提供了评估燃料处理效果和有效性的测量数据。原始出版日期为2017年11月14日。于2022年11月17日进行了少量元数据更新。
