Abstract

We proposed a photosynthetically available radiation dependent primary productivity model. A vertical distribution of PAR is defined as an empirical equation of the chlorophyll-a concentration in the surface, which is observed by an ocean color sensor. A vertical distribution of chlorophyll-a concentration is defined as an empirical equation of the vertical distribution of PAR and the chlorophyll-a concentration in the surface. A vertical distribution of primary productivity is defined as an empirical equation of the vertical distribution of PAR and the temperature. We retrieved those empirical equations from the previous in-situ measurement. A primary productivity of the water column is given as an integration of those parameters along the water column. Results of primary productivity model, applied on a series of SeaWiFS data, showed a good agreement with in-situ observation.
