Ecosystem science, policy, and management informed by the best data and models

Why PEcAn?

Climate change science has witnessed an explosion in the amount and types of data that can be brought to bear on the potential responses of the terrestrial carbon cycle and biodiversity to global change. Many of the most pressing questions about global change are limited by our ability to synthesize existing data. Predictive Ecosystem Analyzer (PEcAn) project specifically seeks to improve this ability. Ultimately, PEcAn aims to make ecosystem modelling and data assimilation routine tools for answering scientific questions and informing policy and management.

How does PEcAn do that?

PEcAn consists of 1) state-of-the-art ecosystem models that themselves are scaffolds for integrating multiple data sources and theory, 2) a workflow management system to handle the numerous streams of data, and 3) a data assimilation statistical framework in order to synthesize the data with the model. PEcAn automates analyses aimed at understanding and forecasting ecosystem responses through these models.

Transparency, repeatability, accessibility

PEcAn's scientific workflow management fully captures the informatics of where the model inputs came from, how they were processed, how sets of model runs were completed, and how the model output was post-processed and visualized for maximizing transparency and repeatability. PEcAn's intuitive web-based interface allows non-modelers or novices to use models and techniques developed by experts.

High functionality and performance

In addition to making the PEcAn source code open source, the system is also available as a fully functional virtual application that runs on a wide range of operating systems. The system can also interact with remote high-performance computing environments, allowing model runs to be done in parallel on remote clusters. Lastly, we're moving to use software containers to make PEcAn even more light weight and easy to use as well as implementing an API to turn PEcAn into a SaaS product.
