通过结合以前发展的机理模型中简化的组件，描述了一个完整的浮游植物生长动态模型，该模型模拟了浮游植物生长随氨氮、硝酸盐、光、铁、硅、磷和温度的变化。可以安全地向基础模型添加或删除描述铵-硝酸盐-光相互作用的组件，以适应特定的建模场景。生物量用C和细胞来描述，而叶绿素也是一个状态变量，可以用光驯化来模拟Chla：C的变化。该模型能够模拟硅、铁或磷限制下的可变硅沉积(硅藻)和C晶胞(-1)。给出了包括温度控制营养物质运输、生长速度和细胞大小的机制。该模型适合放置在生态系统模型中，包含各种组件，可以很容易地修改这些组件以调整模拟，以模拟特定藻类或物种的行为，其中大多数组件具有生物学意义，可以通过实验或对现有数据的分析进行估计。
Developed by combining components simplified from previously developed mechanistic models, a complete dynamic model is described for simulating the growth of phytoplankton as functions of ammonium, nitrate, light, iron, silicon, phosphorus and temperature. Components may be safely added or deleted to the base model, describing ammonium-nitrate-light interactions, to suit particular modelling scenarios. Biomass is described in terms of C and cells, while chlorophyll is also a state variable enabling the simulation of changes in Chl a:C with photoacclimation. The model is capable of simulating variable silicon deposition (diatoms) and C cell(-1) with Si, Fe, or P limitations. Mechanisms for inclusion of temperature control of nutrient transport, growth rate and cell size are given. The model is suitable for placement in ecosystem models, containing various components that can be readily modified to tune the simulation to mimic the behaviour of specific algal groups or species, Most of those components have biological significance and can be estimated from experiments or by analysis of existing data.
