HAQES 3-Hourly Ensemble mean surface total PM2.5 concentration at census level, North America V1 (HAQES_NA_PM25_TOT_CENSUS) at GES DISC

This product provides HAQES 3-hourly ensemble mean surface total PM2.5 concentration at the census level over the continental United States (CONUS).

The Hazardous Air Quality Ensemble System (HAQES) is a real-time ensemble forecast of hazardous air quality events, such as wildfires, dust storms, and Volcanic eruptions. Both regional and global models from multiple agencies are used to create the ensemble, including the Goddard Earth Observing System (GEOS) from the National Aeronautics and Space Administration (NASA), the Navy Aerosol Analysis and Prediction System (NAAPS) from Naval Research Laboratory, the Global Ensemble Forecast System Aerosols (GEFS), High-Resolution Rapid Refresh (HRRR), and National Oceanic and Atmospheric Administration-U.S. Environmental Protection Agency (NOAA-EPA) Atmosphere-Chemistry Coupler-Community Multiscale Air Quality model (NACC-CMAQ) from NOAA. The prototypes of HAQES products were developed by the George Mason University Air Quality Laboratory as part of the NASA Health Air Quality Applied Science Team (HAQAST).

本数据集提供美国本土（Continental United States, CONUS）范围内以人口普查单元为统计单位的逐3小时集合平均近地面总PM2.5浓度数据。
危险空气质量集合预报系统（Hazardous Air Quality Ensemble System, HAQES）是针对野火、沙尘暴、火山喷发等有害空气质量事件的实时集合预报系统。该集合预报整合了多机构的区域与全球模式，包括美国国家航空航天局（NASA）的戈达德地球观测系统（GEOS）、美国海军研究实验室研发的海军气溶胶分析与预报系统（NAAPS）、全球集合预报系统气溶胶模块（GEFS）、高分辨率快速刷新预报模型（HRRR），以及美国国家海洋和大气管理局（NOAA）与美国环境保护署（EPA）联合开发的大气化学耦合器-社区多尺度空气质量模型（NACC-CMAQ）。HAQES产品的原型由乔治梅森大学空气质量实验室开发，作为美国国家航空航天局（NASA）健康空气质量应用科学团队（Health Air Quality Applied Science Team, HAQAST）的研究项目之一。
