BackForward Variable: Water-leaving spectral radiance

Full name Water-leaving spectral radiance
Definition Upward spectral radiance from the ocean surface, i.e. amount of light leaving the ocean per unit area, per wavelength and per solid angle.
Measuring Units W .m-2 . sr-1 .nm-1 Uncertainty Units %
Horizontal Res Units Vertical Res Units
Stability Units (Stability /decade)


Comment: Basic measurement for monitoring the ocean colour, which can inform on ocean plankton concentration
