Description:Products derived from remote sensing re flectances ( RrsλðÞ), for example, chlorophyll, phytoplankton carbon, euphotic depth, or particle size, are widely used in oceanography. Problematically, RrsλðÞm a yh a v ef e w e r degrees of freedom (DoF) than measured wavebands or derived products. Here, we show that a global sea surface hyperspectral RrsλðÞdataset has DoF =4. MODIS-like multispectral equivalent in situ data also have DoF=4, while their SeaWiFS equivalent has DoF =3. Both multispectral-equivalent datasets predict indi- vidual hyperspectral wavelengths ’RrsλðÞwithin nominal uncertainties. Remotely sensed climatological multi-
