NARSTO EPA_SS_LOS_ANGELES PM2.5 Particulate Nitrate

The NARSTO_EPA_SS_LOS_ANGELES_PM25_NITRATE data were collected between July 2001 and January 2002. At Claremont and Rubidoux (Los Angeles County, California), Cascaded Integrated Collection and Vaporization System for Particulate Nitrate (ICVS for Nitrate) was used in a mobile trailer to collect PM2.5 particulate nitrate data during July 11, 2001 to January 11, 2002. The ICVS for Nitrate measured PM2.5 particulate nitrate data that cover sizes from 0.1-2.5um in every 10 minutes.The overall objective of the Los Angeles Supersite in Southern California Particle Center and Supersite (SCPCS) is to conduct monitoring and research that contributes to a better understanding of the measurement, sources, size distribution, chemical composition and physical state, spatial and temporal variability, and linkages to health effects of airborne particulate matter in the Los Angeles Basin.The U.S. EPA Particulate Matter (PM) Supersites Program was an ambient air monitoring research program designed to provide information of value to the atmospheric sciences, and human health and exposure research communities. Eight geographically diverse projects were chosen to specifically address these EPA research priorities: (1) to characterize PM, its constituents, precursors, co-pollutants, atmospheric transport, and its source categories that affect the PM in any region; (2) to address the research questions and scientific uncertainties about PM source-receptor and exposure-health effects relationships; and (3) to compare and evaluate different methods of characterizing PM including testing new and emerging measurement methods.NARSTO (formerly North American Research Strategy for Tropospheric Ozone) is a public/private partnership, whose membership spans government, the utilities, industry, and academe throughout Mexico, the United States, and Canada. The primary mission is to coordinate and enhance policy-relevant scientific research and assessment of tropospheric pollution behavior; activities provide input for science-based decision-making and determination of workable, efficient, and effective strategies for local and regional air-pollution management. Data products from local, regional, and international monitoring and research programs are available.NARSTO_EPA_SS_LOS_ANGELES_PM25_NITRATE数据集采集于2001年7月至2002年1月期间。在加利福尼亚州洛杉矶县的克莱尔蒙特（Claremont）与鲁比杜克斯（Rubidoux）站点，研究人员于2001年7月11日至2002年1月11日期间，在移动实验车内使用颗粒物硝酸盐级联集成收集与汽化系统（Cascaded Integrated Collection and Vaporization System for Particulate Nitrate，简称ICVS for Nitrate）采集PM2.5颗粒物硝酸盐数据。该ICVS for Nitrate可每10分钟采集一次粒径范围为0.1~2.5μm的PM2.5颗粒物硝酸盐数据。 南加州颗粒物中心与超级站点（Southern California Particle Center and Supersite, SCPCS）下属洛杉矶超级站点的总体目标是开展监测与研究，以深化对洛杉矶盆地大气颗粒物的测量方法、排放源、粒径分布、化学组成与物理状态、时空变异性，以及其与健康效应关联机制的认知。 美国环境保护署（U.S. Environmental Protection Agency, EPA）颗粒物（Particulate Matter, PM）超级站点项目是一项环境空气监测研究计划，旨在为大气科学、人类健康与暴露研究领域提供具有应用价值的信息。该项目遴选了8个地理分布各异的研究课题，以针对性落实EPA的核心研究方向：1. 表征任意区域内颗粒物（PM）及其组分、前体物、协同污染物、大气传输过程与影响PM的源类别；2. 解答有关PM源-受体关系与暴露-健康效应关联的研究问题与科学不确定性；3. 对比并评估各类PM表征方法，包括测试新型及前沿的测量技术。 NARSTO（前身为北美对流层臭氧研究战略，North American Research Strategy for Tropospheric Ozone）是一项公私合作伙伴计划，其成员涵盖墨西哥、美国与加拿大三国的政府部门、公用事业单位、工业界与学术机构。该计划的核心使命是协调并推进与政策相关的对流层污染行为科学研究与评估工作，其产出可为基于科学的决策制定，以及制定可行、高效的局地与区域空气污染管理策略提供支撑。目前可获取来自局地、区域及国际监测与研究项目生成的数据产品。
