Data summaries and visualizations for projected Canadian Forest Fire Danger Rating System (CFFDRS) metrics within Fire Danger Rating Areas in Alaska (1980–2099)

Customized products were created for fire management partners in Alaska by leveraging projected Canadian Forest Fire Danger Rating System metrics produced by Young et al. (2025). This input dataset contains daily projections from 1980 through 2099 for key fire danger metrics including Buildup Index, Drought Code, Duff Moisture Code, Fine Fuel Moisture Code, Fire Weather Index, and Initial Spread Index. Using Python and R, we processed these data to produce summary tables, time series plots, and maps tailored for fire management decision support. Most outputs were spatially summarized to 16 Fire Danger Rating Areas, corresponding to the boreal forest extent of the input dataset. These climate-informed projections provide insights into fire danger by capturing changes in fuel moisture, drought, and shifting precipitation and temperature patterns. The resulting data products aim to provide actionable, locally relevant fire danger information to support fire planning and management under future conditions in Alaska.

本数据集依托Young等人（2025）生成的加拿大森林火险等级系统（Canadian Forest Fire Danger Rating System）预测指标，为阿拉斯加消防管理合作伙伴定制开发。该输入数据集包含1980年至2099年的逐日预测数据，涵盖核心火险指标，包括累积指数（Buildup Index）、干旱码（Drought Code）、腐殖质湿度码（Duff Moisture Code）、细燃料湿度码（Fine Fuel Moisture Code）、火险天气指数（Fire Weather Index）以及初始蔓延指数（Initial Spread Index）。研究团队借助Python与R语言对这些数据进行处理，生成适配消防管理决策支持的汇总表格、时序图与专题地图。多数输出结果已按16个火险等级区域（Fire Danger Rating Areas）完成空间汇总，与输入数据集的北方森林覆盖范围相匹配。这些基于气候的预测数据通过捕捉燃料湿度、干旱状况以及降水与温度格局的变化，为火险形势提供科学洞察。最终生成的数据产品旨在提供可落地、贴合本地需求的火险信息，以支撑阿拉斯加未来气候情景下的火灾规划与管理工作。
