Populations and territories exposed to exceedance of the NO2 limit value on the SACs of the Grand-Est region for the year 2022

Populations and territories exposed to exceedance of the NO2 limit value (40 µg/m³) on the administrative surveillance zones (SAZs) of the Grand-Est region for the year 2022. The indicator of exceedance of the limit value of 40 µg/m³ on an annual average for NO2 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.本数据集针对2022年大东部大区（Grand-Est）行政监测区（SAZs），统计二氧化氮（NO₂）年均值超过40微克/立方米（µg/m³）限值的暴露人口与受影响区域。 二氧化氮年均值超40微克/立方米限值的相关统计指标，涵盖受影响居民总数、受影响累计面积及涉事道路长度。本次数据通过大东部大区AAGs与RAZs区域的本地大气扩散模型，以及大区层面针对RZ的区域模型构建生成，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（LCSQA）的业务参考体系相关建议开展。人口统计数据来源于Pop Majic存储库。
