摘要
以苏州市为例,利用2013-2014年MODIS高分辨率大气气溶胶卫星遥感产品对国控空气监测点位布设调整方案进行评估论证,通过提取2 km和5 km半径范围的PM2.5遥感观测数据,与现有国控布设点位的地面监测数据进行相关性分析后,确定卫星产品用于评估验证是可靠的;通过不同天气场下PM2.5月均值浓度分布的比较,表明调整后空气点位布设具有很好的代表性。
MODIS high resolution aerosol remote sensing product in 2013 -2014 was used to assess the adjustment scheme for Suzhou air quality stations. After verifying remote sensing products were correlated to ground - based PM2.5 mass concentration measured by Suzhou air quality stations, annual average PM2.5 mass concentration, monthly average PM2.5 mass concentration and PM2.5 mass concentration in different types of weather divided by an objective weather classification technique were compared between adjustment scheme and current scheme. The results showed that the adjustment scheme for air quality stations was well representative.
