+A new 5-bands scheme is also available (\np[=.true.]{ln_qsr_5bd}{ln\_qsr\_5bd}).
+It is an extension of the RGB scheme by adding a fifth ultra-violet component (UV) to the 4 other wavebands.
+As for the RGB scheme, the UV waveband follows the same power-law as described in \cite{morel_JGR88} and \cite{morel.maritorena_JGR01}.
+The chlorophyll-dependent attenuation coefficients are also derived from these articles.
+The proportion of each band is set up in the namelist by using \np{rn_abs}{rn\_abs} to define the near-infrared proportion and
+\np{rn_par}{rn\_par} to define the visible proportion. The UV proportion is then simply determined by $1 - rn\_abs - rn\_par$.
+
 The trend in \autoref{eq:TRA_qsr} associated with the penetration of the solar radiation is added to
 the temperature trend, and the surface heat flux is modified in routine \mdl{traqsr}.
