POLDER多角度、多通道偏振探测器对地遥感观测研究进展

A Review on Remote Sensing from POLDER Multispectral,Multidirectional and Polarized Measurements

由法国空间研究中心(CNES)于2004年12月18日发射的PARA SOL(Po larization&A n isotropy of R eflectances for A tm ospheric Sciences coup led w ith Observations from a L idar)卫星,是法国和美国合作的“卫星列车”(“A-T rain”)计划中的一员,上面主要搭载了POLDER(Po larization and D irectionality of the E arth's R eflectances)仪器,可以通过全球观测,从空间收集地气系统反射太阳辐射的偏振性和方向性数据。从这些数据,我们可以获得地表、大气气溶胶及云的多种特性,这些信息是改进气候数值模式所必需的。主要以POLDER仪器为例,就多光谱、多角度和多偏振联合遥感观测地气系统方面的进展进行综述。

PARASOL （Polarization ＆-Anisotropy of Reflectances for Atmospheric Sciences coupled with Observations from a Lidar）launched by CNES on Dec. 18, 2004 is one of the French-U. S. satellite project called ＂A-Train＂. It is carrying a wide-field imaging radiometer/polarimeter called POLDER（Polarization and Directionality of the Earth＇s Reflectances）which could collect the directionality and polarization of light reflected by the earth and atmosphere. The information of surfaces, clouds and aerosols derived from the measurements is needed to improve the climate numerical model. The research progress on remote sensing from satellite multispectral, muhidirectional and polarized measurements is summarily reviewed in this paper, especially for the POLDER instrument.
