摘要:

鉴于多角度偏振辐射数据可以有效提升大气气溶胶参数的反演精度,设计了多角度偏振探测航空实验及数据处理流程。将我国自主研制的多角度偏振成像仪DPC搭载在航空平台上,同时在地面布设太阳辐射计CE318观测站点,设计航线串联地面观测站点,开展了航空飞行实验。对实验获得的数据进行分析处理,结果表明,多角度偏振探测航空实验可获取高精度的偏振、辐射数据;使用该数据反演大气气溶胶光学厚度,反演误差小于3%,初步验证了多角度偏振成像仪可为大气气溶胶多参数反演提供有效的数据。

Abstract:

A combination of multi-angle polarization and radiation data can be more effectively improve the inversion precision of atmospheric aerosol parameters, so the airborne experiment is designed and completed to obtain multi-angle polarization and radiation data. The self-developed multi-angle directional polarized camera (DPC) is equipped on the aircraft, and sun-photometer CE318 is mounted at ground stations, then aviation flight experiment was carried out by designing aircraft’s course series ground stations. Processing of data obtained from airborne experiment, the results show that DPC on the aircraft can obtain high precision polarization and radiation data. The atmospheric aerosols optical depth is retrieved using the experiment data, and inversion error is less than 3%, which demonstrates validity of multi-angle polarization and radiation data from airborne experiment.

Key words: atmospheric aerosol, multi-angle directional polarized camera, Airborne Test, polarization reflectance, optical thickness
