Air quality data (data stream E1a) — Validated individual values 2013 (dataset)

Data stream E1a includes measured (link to data stream D) individual values of gaseous pollutants (e.g. ozone, nitrogen dixoid, sulphur dioxide, carbon monoxide), particulate pollutants (e.g. particulate matter, soot, total dust) and dust constituents (e.g. heavy metals, PAHs in PM10, PM2.5, TSP) and the total deposition (BULK), wet deposition and meteorological measurements (e.g. temperature, wind speed, air pressure) for which data reporting is mandatory. The report also includes the data quality objectives (measurement uncertainty, time coverage meets yes/no, minimum data capture meets yes/no) and information on concentration values is attributable to natural sources and the spread of sand and salt (concentration values without any correction deductions).数据流E1a包含实测的各类监测单值（数据链接至数据流D），涵盖以下类别：气态污染物（臭氧、二氧化氮、二氧化硫、一氧化碳）、颗粒物污染物（颗粒物、烟尘、总尘）、粉尘组分（PM10、PM2.5及总悬浮颗粒物（TSP, Total Suspended Particulates）中的重金属、多环芳烃（PAHs, Polycyclic Aromatic Hydrocarbons）），以及总沉降（BULK）、湿沉降与强制上报的气象观测数据（含气温、风速、气压等）。本数据集同时包含数据质量目标相关内容：测量不确定度、时间覆盖率达标情况（是/否）、最低数据采集率达标情况（是/否），并附带浓度值可归因于自然源、沙尘与盐粒扩散的说明信息（即未经过任何校正扣减的原始浓度值）。
