[ABSTRACT] A water column distribution of photosynthetically available radiation (PAR) was modeled based on the chlorophyll-a concentration in the surface layer with an empirical equation to support a depth and time resolved primary productivity model. A vertical distribution of PAR exhibited a variation for certain chlorophyll-a concentration, where a variation of diffused attenuation coefficient is expected. An empirical equation was proposed to model an optimum vertical distribution of PAR with chlorophyll-a concentration in the surface layer. This optically optimized PAR dependent depth and time resolved primary productivity model was validated with the in-situ measurements on the Equatorial Pacific, the East China Sea, and the Northwestern Pacific. The result indicated a good correlation between the model estimated primary productivity and the in-situ measurements, where the model showed a significant improvement from the previous one.
