Spectral bias of reported Rrs compared with 3C-modeled Rrs from 1589 spectra for which Lt, Lsky and Es were available. (A) Median and interquartile (reported - modeled). (B) Relative bias in Rrs (reported - modeled)/modeled. Discontinuities in the bias spectrum are caused by sensors having different wavelength ranges within parts of the dataset.
