This work aims at commenting requirements and conclusions in a recent paper [Wei et al., Opt. Express29, 2780 (2021)10.1364/OE.413784] presenting an evaluation of the precision of water-leaving radiance measurements from a near-surface method. Specifically, this work challenges the uncertainty requirements indicated for satellite ocean color system vicarious calibration resulting from an erroneous interpretation of literature, and an incorrect application of radiometry principles leading to a misestimate of the difference between radiances collected by nadir-view optical sensors operated below and above the water surface.
