Current particulate matter concentration (pm10) in the Netherlands

This map shows the calculated fine dust concentrations (PM10) of the last hour. You see especially high concentrations on busy roads and businesses. Some of the fine dust comes from abroad. The concentration is expressed in micrograms per cubic meter (µg/m³). PM10 stands for Particulate Matter, where the particles have a diameter smaller than 10 micrometers. The values you see are based on calculations. The calculations are calibrated to several measurements in the country. The calculation method used is the Derivative Standard Calculation Method 2, where it is traced back to hourly values.本地图展示了过去一小时内测算得到的细颗粒物（PM10）浓度。可见交通繁忙路段与工商业区域的浓度尤其偏高。部分细颗粒物源自境外。浓度单位为微克每立方米（µg/m³）。PM10即颗粒物（Particulate Matter），指粒径小于10微米的大气颗粒物。 本数据集展示的数值均基于模型测算，该测算流程已针对该国境内的多组实测数据完成校准，所采用的衍生标准计算方法2（Derivative Standard Calculation Method 2）可将输出结果溯源至逐小时统计值。
