Air Quality System (AQS) Monitoring Network - EPA OAQPS

Full Metadata This U.S. EPA Office of Air and Radiation (OAR) - Office of Air Quality Planning and Standards (OAQPS) web service contains the following air quality monitoring network point location layers: CO (carbon monoxide), Lead, Lead-TSP(LC) (lead, total suspended particulates, local conditions), Lead-PM10(LC) (lead, particluate matter up to 10um in size, local conditions), NO2 (nitrogen dioxide), Ozone, PM10 (particulate matter up to 10um in size), PM2.5 (particulate matter up to 2.5um in size), SO2 (sulfur dioxide), PM2.5 Chemical Speciation Network, IMPROVE (Interagency Monitoring of Protected Visual Environments), NATTS (National Air Toxics Trends Stations), NCORE (Multipollutant Monitoring Network). Layers are drawn at all scales. Security classification: Public. Access constraints: None. Use constraints: None. Please check sources, scale, accuracy, currency and other available information. Please confirm that you are using the most recent copy of both data and metadata. Acknowledgement of the EPA would be appreciated.完整元数据 本数据集源自美国环境保护署（U.S. EPA）空气与辐射办公室（Office of Air and Radiation, OAR）下属的空气质量规划与标准办公室（Office of Air Quality Planning and Standards, OAQPS）的网络服务，包含以下空气质量监测网络点位图层：一氧化碳（carbon monoxide, CO）、铅（Lead）、铅-总悬浮颗粒物（Lead-TSP(LC)，即铅、总悬浮颗粒物，适配本地工况）、铅-PM10(LC)（即铅、粒径≤10μm的颗粒物，适配本地工况）、二氧化氮（nitrogen dioxide, NO2）、臭氧（Ozone）、PM10（粒径≤10μm的颗粒物）、PM2.5（粒径≤2.5μm的颗粒物）、二氧化硫（sulfur dioxide, SO2）、PM2.5化学组分监测网络、跨机构保护视觉环境监测网（Interagency Monitoring of Protected Visual Environments, IMPROVE）、国家空气毒物趋势监测站（National Air Toxics Trends Stations, NATTS）、多污染物监测网络（Multipollutant Monitoring Network, NCORE）。所有图层均可在任意比例尺下展示。安全密级：公开。访问限制：无。使用限制：无。请核查数据源、比例尺、精度、时效性及其他可用相关信息；请确认使用的为数据与元数据的最新版本。若能对美国环境保护署予以致谢，将不胜感激。
