The effects of oceanic whitecaps on ocean-color imagery are simulated and inserted into the proposed Sea-Viewing Wide-Field-of-View Sensor (SeaWiFS) atmospheric-correction algorithm to understand its tolerance to error in the estimated whitecap contribution. The results suggest that for wind speeds ≲ 10-12 m/s, present models that relate whitecap reflectance to wind speed are sufficiently accurate to meet the SeaWiFS accuracy goal for retrieval of the water-leaving radiance in the blue, when the aerosol scattering is weakly dependent on wavelength. In contrast, when the aerosol scattering has a strong spectral signature, the retrievals will meet the goal only when the whitecap reflectance is underestimated.
模拟了海洋白帽对海洋颜色图像的影响，并将其插入到拟议的宽视场海洋观测传感器（SeaWiFS）大气校正算法中，以了解其对估计白帽贡献误差的耐受性。结果表明，对于风速≲10-12米/秒，当气溶胶散射对波长的依赖性较弱时，目前将白帽反射率与风速相关联的模型足够准确，能够满足SeaWiFS在蓝色波段反演离水辐亮度的精度目标。相比之下，当气溶胶散射具有很强的光谱特征时，只有在白帽反射率被低估的情况下，反演结果才能达到目标。
