A multiscale study of the coupling between flow, fire and vegetation static field experiments: three-dimensional wind and temperature from 2022-2025

This dataset contains sonic anemometer data collected during multiple static field experiments at Tall Timbers Station and Land Conservancy (TT) in October 2022 and the Savannah River Site (SRS) between May 2023 and June 2025. Horizontal and vertical wind speed and temperature were collected at 10-Hz.The data is from a series of experiments using liquid pool fires and small-scale laboratory work to characterize the way structure and heterogeneity of fuel elements change the drag and convective heat transfer in plume dynamics. Other datasets were collected and complement this dataset as part of the Department of Defense project RC20-1362. All related datasets titles start with "A multiscale study of the coupling between flow, fire and vegetation static field experiments:".The TT field experiments were conducted using multiple liquid pool fire (pan) configurations on a clearing where all vegetation was removed. Nine sonic anemometers were mounted on towers downwind from the pans in three arrays at 6, 10 and 30-ft (1.8, 3 and 9.1-m) heights. A control sonic was located 14.6-m upwind of the center pan on a 5-ft (1.5-m) tower.The SRS field experiments were conducted using multiple pan configurations within a 2-ha loblolly and long leaf pine plantation. Understory vegetation was removed in all burns and tree density reduced in some burns. Nineteen sonic anemometers were mounted on 11 towers around the pan configurations at heights 6, 10, 25 and 40-ft (1.8, 3, 7.6 and 12.2-m). Tower configurations were changed due instrument availability and prevailing winds.For exact sonic location and pan configuration for each burn, see burn layout and documentation in the dataset: A Multiscale study of the coupling between flow, fire and vegetation: field experiments â burn layout and documentation (https://doi.org/10.60594/W4NC73, see Annotations section for Metadata link).

本数据集包含2022年10月在高提伯斯站与土地保护协会（Tall Timbers Station and Land Conservancy，简称TT），以及2023年5月至2025年6月在萨凡纳河站点（Savannah River Site，简称SRS）开展的多场静态野外实验中采集的超声风速仪（sonic anemometer）数据。实验以10赫兹的频率采集水平风速、垂直风速与气温数据。本数据集源自一系列结合液态池火（pan）试验与小型实验室工作的研究，旨在表征燃料组分的结构与异质性如何改变羽流动力学中的阻力与对流传热特性。作为美国国防部RC20-1362项目的组成部分，另有其他数据集对本数据集进行补充。所有相关数据集的标题均以"A multiscale study of the coupling between flow, fire and vegetation static field experiments:"开头。TT野外实验在一处清除了所有植被的开阔地上开展，采用多种液态池火（燃烧槽）构型。9台超声风速仪以3组阵列的形式布设在池火下风侧的塔架上，架设高度分别为6、10与30英尺（即1.8、3与9.1米）。另有1台对照超声风速仪布设在中心池火上风侧14.6米处的5英尺（1.5米）高塔架上。SRS野外实验在一片面积为2公顷的火炬松（loblolly pine）与长叶松（long leaf pine）人工林内开展，采用多种池火构型。所有火烧作业均移除了林下植被，部分火烧作业还降低了林木密度。19台超声风速仪布设在池火构型周边的11座塔架上，架设高度分别为6、10、25与40英尺（即1.8、3、7.6与12.2米）。塔架布设方案会根据仪器可用情况与盛行风向进行调整。如需获取每场火烧作业的精确超声风速仪布设位置与池火构型，请参阅本数据集内的《A Multiscale study of the coupling between flow, fire and vegetation: field experiments – burn layout and documentation》（https://doi.org/10.60594/W4NC73，元数据链接请参见注释部分）。
