Air quality data (data stream D) - Assessment methods 2015 (data set)

Data stream D comprises the meta-information on the area-based assessment methods resulting from the assessment regime (data stream C). For the fixed and indicative measurements, this is the material-specific meta-information about the measuring stations, such as name, code, measurement configuration, station classification, data quality objectives, etc. The link to the assessment areas (data stream B) is made via the coordinates of the measuring stations.数据流D包含源自评估体系（数据流C）的基于区域的评估方法相关元信息。针对固定测量与指示性测量，此类元信息为与特定物料相关的测量站元信息，涵盖测量站名称、编码、测量配置、站分类、数据质量目标等内容。可通过测量站的坐标建立与评估区域（数据流B）的关联。
