Wildland fire PM2.5 modeled estimates for the US from 2008-2018

This dataset includes daily modeled wildland fire PM2.5 concentrations for 2008-2018 for the state of California at a 12-km grid spatial resolution, estimated using the U.S. EPA’s Community Multiscale Air Quality (CMAQ) (v. 5.0.1- 5.3) modeling system. These wildland fire emissions estimates (which include wildfires and prescribed burns [but exclude agricultural burns]) incorporate multiple sources of fire activity. SMARTFIRE2 was used to reconcile the sources of fire activity data. Fuel consumption was calculated using the U.S. Forest Service’s CONSUME ver. 3.0 fuel consumption model and the Fuel Characteristic Classification System (FCCS) fuel-loading database in the BlueSky Framework. Emission factors were taken from the Fire Emission Production Simulator (FEPS) model. Non-fire emissions sources are from the National Emissions Inventory (NEI). The model was run with all emissions (fire and non-fire sources) and again without fires. The calculated difference between these simulations ..., The data have been processed from .ncf files into .tif files. Data were developed by Joseph Wilkins, Howard University. , , # Wildland fire PM2.5 modeled estimates for the US from 2008-2018 [https://doi.org/10.5061/dryad.sxksn03b3](https://doi.org/10.5061/dryad.sxksn03b3) ## Description of the data and file structure These are raster .tif files with daily wildland fire PM2.5 concentrations across the United States CMAQ grid. There is one file included for each year. The grid changes from the 12US1 domain to the 12US2 domain starting in the year 2013.Â本数据集涵盖2008年至2018年加利福尼亚州（California）范围内、空间分辨率为12千米网格的逐日模拟野火细颗粒物（PM2.5）浓度数据，其估算基于美国环境保护署（U.S. EPA）的社区多尺度空气质量模型（Community Multiscale Air Quality，CMAQ）版本5.0.1至5.3所搭建的模拟系统。本次野火排放估算（涵盖野火与计划烧除，但不包含农业烧荒）整合了多类火灾活动源数据，并通过SMARTFIRE2工具对火灾活动数据源进行协调校正。燃料消耗量通过美国林务局（U.S. Forest Service）的CONSUME 3.0版燃料消耗模型，以及BlueSky框架内的燃料特征分类系统（Fuel Characteristic Classification System，FCCS）燃料荷载数据库计算得到。排放因子取自火灾排放生产模拟器（Fire Emission Production Simulator，FEPS）模型。非火灾排放源数据来自国家排放清单（National Emissions Inventory，NEI）。该模型分别在纳入全部排放（火灾与非火灾源）以及仅纳入非火灾排放的条件下运行，通过两组模拟结果的计算差值……，数据已从.ncf格式文件处理为.tif格式文件。本数据集由霍华德大学（Howard University）的Joseph Wilkins研发。 # 美国2008-2018年野火细颗粒物（PM2.5）模拟估算数据集 数据集DOI：https://doi.org/10.5061/dryad.sxksn03b3 ## 数据与文件结构说明 本数据集为覆盖美国CMAQ网格的逐日野火细颗粒物浓度栅格.tif文件，每年对应一个数据文件。自2013年起，网格域从12US1变更为12US2。
