Primary production of the Arctic Ocean

This algorithm returns the daily primary production through the euphitic depth of the water column (PPeu) in mg C/m2/day. PPeu was calculated using an algorithm modfied from Hirawake et al (2012). Photosynthesis activity, phytoplankton biomass index, euphotic zone depth were computed from spectral remote sensing reflectance. Level-3 standard maiing images of the input variables of the algorithm, remote sensing reflectance and daily mean photosynthetic available radiation (PAR) products, were obtained from GSFC/NASA.
