GMIS - SeaWiFS Monthly mean primary production (9km) in gC.m^-2.day^-1

Water productivity (primary production, pp in gCarbon.m-2.day-1 at 9km resolution): The primary production represents the amount of organic carbon produced through phytoplankton photosynthesis. It is a critical element of the Earth's carbon budget and the marine food web. The depth-integrated primary production is modeled from the satellite-based phytoplankton biomass concentration and PAR.

水生产力（Water productivity）：即初级生产（primary production，缩写pp），单位为克碳·平方米⁻²·天⁻¹，空间分辨率为9千米。初级生产指通过浮游植物光合作用生成的有机碳总量，是地球碳收支与海洋食物网的关键组成部分。深度积分初级生产数据由基于卫星的浮游植物生物量浓度与光合有效辐射（Photosynthetically Active Radiation，PAR）建模得到。
