Populations and territories exposed to exceedance of the PM2.5 limit value on the SACs of the Grand-Est region for the year 2020

Populations and territories exposed to exceedance of the PM2.5 limit value (25 µg/m³) on the administrative surveillance zones (SAZs) of the Grand-Est region for the year 2020. The indicator of exceedance of the limit value of 25 µg/m³ on an annual average for PM2.5 corresponds to the number of inhabitants affected, the cumulative area and the road length concerned. Data created with a local atmospheric dispersion model for AAGs and RAZs in the Grand-East region and at the regional level for the RZ. Use of the Grand-East Region Emissions Inventory. Modelling carried out in accordance with the recommendations of the Business Reference System of the Central Air Quality Monitoring Laboratory (LCSQA). Demographic data is derived from the Pop Majic repository.本数据集统计了2020年大东部大区（Grand-Est）行政监测区（Administrative Surveillance Zones，SAZs）范围内，PM2.5浓度超过25 μg/m³限值的暴露人口与覆盖区域。 该PM2.5年均值25 μg/m³的超标统计指标，包含受影响居民数量、累计受影响面积及相关道路长度三类统计项。数据集依托大东部大区AAGs与RAZs的本地大气扩散模型、区域级RZ的相关模型构建，并采用了大东部大区排放清单。建模工作严格遵照中央空气质量监测实验室（Central Air Quality Monitoring Laboratory，LCSQA）的业务参考体系建议执行。人口数据取自Pop Majic存储库。
