摘 要：
京津冀地区是当前我国大气污染最严重的地区.为了形成覆盖式监测能力,使用韩国GOCI静止卫星数据开发了PM_(2.5)高时空分辨率遥感系统,使用卫星气溶胶光学厚度和地面PM_(2.5)进行融合得到小时级PM_(2.5)遥感产品,对观测大气颗粒物空间动态变化具有先天优势.经过京津冀地区的独立地面站点检验,具备小时级高时间分辨率、2 km高空间分辨率的PM_(2.5)遥感产品和地面相关系数R2为0.69,且基于天基遥感数据的观测具有较好的独立性和客观性.长时间遥感观测结果表明,该系统可用于分析京津冀地区PM_(2.5)的空间分布规律.

摘 要：
The Beijing-Tianjin-Hebei is the most air-polluted area in China.To constitute the covering observing ability,the Korea GOCI geostationary satellite data was used to develop a high temporal-spatial PM_(2.5) remote sensing system.The satellite Aerosol Optical Depth and ground-based PM_(2.5) data were fused to get an hourly PM_(2.5) remote sensing product which have advances in aerosol dynamic monitoring.By validation referred to the independent ground sites data,the hourly 2 km resolution PM_(2.5) had 0.69 R2 against the ground data.Also,remote sensing product had the independence and objectivity.With long time measurements,the spatial distribution of PM_(2.5) could be analyzed in Beijing-Tianjin-Hebei area.
