+Develop a standalone module to compute vertical light propagation.
 
-Will use the interface existing in PISCES to define common arrays and infrastructure, along with diagnostic fields (e.g., Light at the euphotic depth, Euphotic layer depth).
+This module will receive surface radiation (namely qsr) from OCE component and the 3D chlorophyll field from the coupled BGC model.
+These data are needed to compute the light attenuation coefficients of each RGB wavelength and the module will return updated fields of '''photosynthetic active radiation (PAR)''' needed for \\
+'''1)''' the BGC feedback toward ocean physics ({{{ln_qsr_bio}}} option) through the updated of {{{etot3}}} 3D field,\\
+'''2)''' vertical distribution of total PAR ({{{etot}}}) and, optionally, the PAR contribution for each wavelength needed to drive BGC models. \\
+
+In the computation of PAR passed to BGC models, two different choices are provided in order to compute a) the water cell light in the cell '''center''' (as in PISCES) or b) the 'integral' of light within the water cell (as in BFM).
+
+Also common diagnostic fields will be included for ight at the euphotic depth, Euphotic layer depth, and weighted broadband attenuation coefficiet.
