Physiological Principles in Predicting Growth (3-PG)

The 3-PG model was developed to bridge the gap between conventional, mensuration-based growth and yield, and process-based carbon balance models. 3-PG calculates the radiant energy absorbed by forest canopies and converts it into biomass production. The efficiency of radiation conversion is modified by the effects of nutrition, soil drought (the model includes continuous calculation of water balance), atmospheric vapour pressure deficits and stand age. Output includes stem biomass and volume, average stem diameters, stand basal area at any time and the time course of Leaf Area Index.

WHAT WE DO
  • Provide training and technical support for modelling activities to research groups at CREAF.
  • Develop and promote the use of process-based and empirical models aimed at predicting the response of terrestrial ecosystems to global change at multiple scales from the forest stand to the region.
  • Facilitate discovery of data sets or models relevant for ecosystem modelling activities.
  • Develop tools aimed at facilitating the interoperability between data sources and models, and between different models.
  • Develop and maintain interactive web applications for ecosystem data exploration and visualization.
