| 摘 要： | 太阳光入射海表特定区域形成海洋耀光,呈强反射和偏振特性。在卫星海洋遥感中,海洋耀光对遥感成像质量有较大影响,尤其对海洋上空云、气溶胶及海色等研究干扰较大,因此剔除海洋耀光是卫星遥感数据处理过程中首先要解决的重要问题。以PARASOL卫星的POLDER3载荷数据为研究对象,获取载荷成像时刻太阳及观测几何、海表风速风向及气溶胶光学厚度等参数,采用海气辐射传输相关理论,结合耀光角和多角度NIR偏振辐射信息(865 nm),构建基于近红外偏振辐射特性规则的OGDD模型,获取耀光角临界值实现耀光动态检测。以印度洋某海区为研究对象,获取实测耀光区NIR通道的大气层顶反射率和偏振反射率,利用OGDD模型将耀光角判别临界值调整为34°。相比MODIS经验临界值(40°),标记耀光像元相对减少了30%。结果表明,该方法不仅能通过动态调整临界值准确识别海洋耀光,为云检测及云物理特性反演提供可靠的源数据,还能为高分五号卫星多角度偏振载荷在轨定标及气溶胶反演提供支持。
