It is having 13 bands in VNIR (400–1010 nm range) with ~ 1500 km swath for monitoring the ocean. Basically it operates in two modes, one is Local Area Coverage (LAC) mode, i.e. 360m resolution and second one is Global Area Coverage (GAC) for global ocean in low resolution mode (1.1 km) at regular cycles. Remote sensing reflectance derived from space using standard atmospheric correction, works very well in open ocean while the same approach fails in the optically complex waters, so to overcome this problem, 870 nm was paired with 1010 nm of OCM-3 instead of 780–870 nm to recover the coastal radiometry basically at blue channels. They suffer a lot because of overestimation of atmospheric characterization at NIR channels and then extrapolated to blue channel during radiative transfer modeling. In addition, absorbing aerosols and coloured dissolved organic matter are equally responsible in coastal region as well. The role of additional bands of ocean colour monitor (OCM-3) was discussed in this manuscript.
