摘要:

PARASOL传感器不仅能够进行偏振观测,而且能够获得标量观测数据。针对PARASOL的传感器特征,在地面典型地物光谱数据分析的基础上,确定了暗目标的识别方法以及地气分离方法,获得了针对PARASOL标量数据的暗目标法反演陆地气溶胶的算法。利用2006年夏季的AERONET北京站的地面数据验证了本算法,结果表明,本算法获得的结果与地面观测结果有较好的相关性(R=0.86),但在气溶胶光学厚度较小时误差较大。

Abstract:

PARASOL can be used in not only polarized measurements, but also intensity measurements. The intensity reflectance of typical land surfaces in PARASOL channels was analyzed, and dark dense vegetation (DDV) algorithm of PARASOL was developed. From PARASOL intensity measurements in the summer of 2006, the aerosol optical depth (AOD) was retrieved by the algorithm. By the comparison with Beijing Site of aerosol robotic network (AERONET), correlation coefficient was equal to 0.86, but when AOD was small, the retrieval error was large.

Key words: remote sensing, aerosol over land surface, polarization, dark dense vegetation
