TL;DR: In this article, a stand growth model, called 3-PG (Use of Physiological Principles in Predicting Growth), calculates total carbon fixed (gross primary production; PG) from utilizable, absorbed photosynthetically active radiation (φp.a.u.), obtained by correcting the photosyntically active radiation absorbed by the forest canopy for the effects of soil drought, atmospheric vapour pressure deficits and stand age.

TL;DR: The constancy of the NPP/GPP ratio supports the possibility of greatly simplifying forest growth models and provides an incentive to renew efforts to understand the environmental factors affecting partitioning of NPP above and belowground.

TL;DR: It is argued that the carbon balance approach is readily applicable for projecting forest yield and productivity, and several carbon balance models for estimating stand productivity and individual tree growth and competition are reviewed.

TL;DR: In this paper, the authors applied these simplifications in a monthly time-step model driven by estimates of the fraction of light intercepted by green canopies, derived from near-infrared and red reflectances monitored from National Oceanographic and Atmospheric Administration (NOAA) weather satellites, and from equations utilising local temperature and rainfall records.

TL;DR: In this article, the 3-PG model is used to predict stand growth in areas where trees have not been grown, i.e. the model can be used to estimate site productivity.
