The air quality network in the Netherlands is based on a regular grid with an interstation distance of 30 to 40 km. In or close to source areas, a higher station density is realized. Atmospheric transport models form an intrinsic part of the air quality monitoring system. The models are constructed in such a way that only routinely available meteorological input data are needed. The models are applied for interpretation and generalization of the measurements in terms of contributions of source categories. In scenario studies, the potential effect of abatement strategies is explored. The output of the models consists of concentration and deposition fields of NOx, NO2, SO2, sulfate, and nitrate on the scale of the Netherlands or on the scale of northwestern Europe. In the present version the models are not directly suitable to estimate exposures to acidic aerosols; however, in combination with limited aerosol measurements, the model predictions can be used to provide information on the spatial and temporal distribution of acidic aerosols as needed for exposure assessment.
荷兰的空气质量监测网络基于间距为30至40公里的规则网格。在源区或其附近，站点密度更高。大气传输模型是空气质量监测系统的固有组成部分。这些模型的构建方式是仅需要常规可得的气象输入数据。这些模型用于根据源类别贡献对测量结果进行解释和归纳。在情景研究中，探索减排策略的潜在效果。模型输出包括荷兰尺度或西北欧尺度上氮氧化物、二氧化氮、二氧化硫、硫酸盐和硝酸盐的浓度及沉降场。在当前版本中，这些模型并不直接适用于估算酸性气溶胶暴露情况；然而，结合有限的气溶胶测量，模型预测可用于根据暴露评估的需要提供酸性气溶胶时空分布的信息。
