WISE statistics - nutrients (1990-2022), 2024

WISE Statistics – Nutrients

The WISE Statistics are aggregated data products for creation of the Freshwater indicators "Oxygen consuming substances in European rivers" and "Nutrients in Freshwater in Europe", which are published at the EEA website.

The data tables provides several aggregation levels, e.g. waterbody, country, Europe. The EEA combines and aggregates the reported data from the annual WISE SoE data flows. Data can be reported on three levels: Disaggregated (individual observations on monitoring site level), aggregated (annual aggregation of observations per monitoring site), aggregated by water body (annual aggregation of observations per water body). The Nutrients AggregatedData table combines reported disaggregated and aggregated data, while all higher aggregation levels can also include data aggregated by water body.

WISE统计数据——营养物质

WISE统计数据是用于生成淡水指标的聚合数据产品，这些指标包括"欧洲河流中的耗氧物质"和"欧洲淡水中的营养物质"，均发布于欧洲环境署（EEA）网站。

数据表提供多种聚合层级，例如水体、国家、欧洲层面。欧洲环境署整合并聚合来自年度WISE SoE数据流的上报数据。数据可在三个层级上报：非聚合（Disaggregated，监测点层面的个体观测数据）、聚合（Aggregated，每个监测点观测数据的年度聚合）、按水体聚合（Aggregated by water body，每个水体观测数据的年度聚合）。营养物质聚合数据表（Nutrients AggregatedData）整合了上报的非聚合和聚合数据，而所有更高层级的聚合数据也可包含按水体聚合的数据。
