Historical and Future Prescribed Burn Windows for the Southeast United States

Prescribed burning is a critical tool for managing wildfire risks and meeting ecological objectives, but its safe and effective application requires that specific meteorological criteria are met. This dataset contains results from a study examining the potential impacts of projected climatic change on prescribed burning in the southeastern United States. A set of burn window criteria (suitable weather conditions within which burning may occur based on maximum daily temperature, daily average relative humidity, and daily average wind speed), were applied to projections from an ensemble of Global Climate Models (GCM) under two greenhouse gas emission scenarios, as well as past observations for comparison. Data are provided as decadal output for observed conditions, and for individual GCM results for the historical climate scenario and the two future climate scenarios are provided. In addition, summary statistics (e.g,. multi-model mean, and for selected quantiles) are provided for the GCM ensemble as a whole by decade.

计划火烧（Prescribed burning）是管控野火风险、达成生态目标的关键工具，但其安全且高效的实施必须满足特定气象准则。本数据集源自一项探究预估气候变化对美国东南部计划火烧潜在影响的研究。研究将一套火烧窗口标准（burn window criteria）——即基于每日最高气温、日均相对湿度与日均风速划定的适宜火烧天气条件，应用于两组温室气体排放情景下的多模式全球气候模型（Global Climate Models, GCM）集合的预测结果，并结合历史观测数据开展对比分析。数据集按十年时段提供观测情景下的输出结果，同时涵盖历史气候情景与两组未来气候情景下各单个GCM的模拟结果。此外，还按十年为单位，提供了整个GCM集合的汇总统计量（例如多模式均值、选定分位数）。
