Populations and territories exposed to exceedance of the PM2.5 limit value on the SACs of the Grand-Est region for the year 2021

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 2021. 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2021年大东部大区（Grand-Est）行政监测区（administrative surveillance zones, SAZs）内PM2.5年均值超过25微克/立方米限值的暴露人口与受影响区域。 针对PM2.5年均值超过25微克/立方米限值的统计指标，涵盖受影响居民人数、累计受影响区域面积及相关道路长度。 数据基于大东部大区AAGs、RAZs区域以及大区层面RZ区域的本地大气扩散模型生成。 本数据集采用大东部大区排放清单。 建模工作严格遵循中央空气质量监测实验室（Central Air Quality Monitoring Laboratory, LCSQA）的业务参考体系相关建议。 人口统计数据源自Pop Majic存储库（Pop Majic repository）。
