Probabilistic Wildfire Risk Flame Length Probability 3 Hawaii (Image Service)

Note: This image service has been consolidated into a unified service that now includes Alaska (AK), the Continental United States (CONUS), and Hawaii (HI). For access to the updated and combined image service, please visit the new item page: https://usfs.maps.arcgis.com/home/item.html?id=7b18a680975241c3b2868f4b5ec2f76e.National data on burn probability (BP) and conditional flame-length probability (FLP) were generated for the conterminous United States (CONUS), Alaska, and Hawaii using a geospatial Fire Simulation (FSim) system developed by the USDA Forest Service Missoula Fire Sciences Laboratory. The FSim system includes modules for weather generation, wildfire occurrence, fire growth, and fire suppression. FSim is designed to simulate the occurrence and growth of wildfires under tens of thousands of hypothetical contemporary fire seasons in order to estimate the probability of a given area (i.e., pixel) burning under current landscape conditions and fire management practices. The data presented here represent modeled BP and FLPs for the United States (US) at a 270-meter grid spatial resolution. Flame-length probability is estimated for six standard Fire Intensity Levels. The six FLPs correspond to flame-length classes as follows: FLP1 = This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

注意：本影像服务已整合为统一服务，现涵盖阿拉斯加（Alaska, AK）、美国本土（Continental United States, CONUS）及夏威夷（Hawaii, HI）。如需访问更新后的合并影像服务，请访问新条目页面：https://usfs.maps.arcgis.com/home/item.html?id=7b18a680975241c3b2868f4b5ec2f76e。美国本土（CONUS）、阿拉斯加与夏威夷的全国火烧概率（burn probability, BP）与条件火焰长度概率（conditional flame-length probability, FLP）数据集，由美国农业部林务局米苏拉火灾科学实验室开发的地理空间火灾模拟（Fire Simulation, FSim）系统生成。FSim系统包含天气生成、野火发生、火行为蔓延及火灾扑救相关模块。该系统旨在模拟数万次假设的当代火灾季内野火的发生与蔓延过程，以估算当前景观条件与火灾管理模式下，给定区域（即像素单元）发生火烧的概率。本次发布的数据集为美国全域（US）范围内空间分辨率为270米的栅格化火烧概率与条件火焰长度概率数据。本次数据针对六个标准火灾强度等级，分别估算了对应的火焰长度概率。六个火焰长度概率类别对应关系如下：FLP1 = 本记录的数据源自纳入https://data.gov目录的美国农业部企业数据清单（USDA Enterprise Data Inventory）。本记录包含以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS地理服务。如需完整信息，请访问https://data.gov。
