CONUS air quality reanalysis dataset (2005-2018)

This 14 year hourly air quality reanalysis dataset is generated through daily assimilation of the Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD) and the Measurement of Pollution in the Troposphere (MOPITT) carbon monoxide (CO) retrievals in the Community Multiscale Air Quality Model (CMAQ) from 01 Jan 2005 to 31 Dec 2018. The production of this air quality reanalysis is funded by the Atmospheric Composition Modeling and Analysis Program (ACMAP) under the project entitled “Quantification and attribution of past (2005-2018) air quality trends over the Contiguous United States (CONUS) via assimilation of NASA atmospheric composition”. This data can be used to (1) develop products and metrics for assessing the long-term impact of air pollution on public health, agriculture, and economy as well as for quantifying air quality changes in unmonitored areas and benefits of emission control policies.

本14年小时级空气质量再分析数据集，通过每日同化中分辨率成像光谱仪（MODIS）气溶胶光学厚度（AOD）和大气对流层污染测量（MOPITT）一氧化碳（CO）检索数据，在社区多尺度空气质量模型（CMAQ）中进行生成，时间跨度为2005年1月1日至2018年12月31日。该空气质量再分析的制作资金由大气成分建模与分析计划（ACMAP）提供，该计划隶属于名为“通过同化NASA大气成分量化并归因于美国本土（CONUS）过去（2005-2018年）空气质量趋势”的项目。该数据可用于（1）开发评估空气污染对公共卫生、农业和经济长期影响的产物和指标，以及量化未监测区域的空气质量变化和排放控制政策效益。
