<p>In this paper, the performance of the sun glint masking algorithm implemented on India’s EOS-06 OCM-3 operational ocean colour products has been evaluated by testing on different glint-contaminated OCM-3 scenes from various parts of the global ocean. The sun-glint-contaminated scenes were taken based on the visible appearance of glint on grayscale radiance images. Sun glint masking was then performed by applying a threshold on normalised glint reflectance, which is estimated from the Cox and Munk model. It was observed that the percentage of pixels in an image lost to sun glint varied from less than 10% to more than 35%, depending on the relative orientation of the sun and sensor. Since OCM-3 operational products use monthly climatological winds for sun glint masking, it was investigated if real-time scatterometer winds can better characterise the sun glint area. Sun glint masking was carried out using both monthly climatological wind fields and real-time EOS-06 scatterometer wind fields, and the difference in masking was evaluated both at the radiance level as well as at the geophysical product level. It was observed that even though climatological winds were very effective in masking high to moderate glint areas, they had some limitations, particularly in flagging mild glint pixels. Incorporating real-time winds for glint masking can provide better characterisation and flagging of glint pixels, as well as improved aerosol optical depth estimation near glint edges.</p>
