The Predictive Ecosystem Analyzer: PEcAn

The Predictive Ecosystem Analyzer (PEcAn) is a framework for running ecosystem models. Our mission is to "Develop and promote accessible tools for reproducible ecosystem modeling and forecasting". It provides a workflow and standard inputs and outputs to support modeling, as well as a Bayesian approach to integrate information contained in biophysical models and data across multiple sources and scales.

We are currently using PEcAn to predict the physiology, growth, and ecology of genetically modified crops before they can be grown in field trials. Previously, we have used PEcAn to predict the productivity and yield stability of bioenergy crops at regional to global scales.
