We are improving the open-source computer model SIPNET that helps scientists understand how ecosystems exchange carbon, water, and nutrients with the atmosphere. Originally designed to simulate carbon and water balance in unmanaged ecosystems, SIPNET has now been extended to simulate carbon, water, and nitrogen balance in actively managed lands such as farms and mixed-use landscapes.


This update adds four key features:



  1. Support for simulating farming activities including planting, harvesting, tillage, and fertilization;

  2. A new nitrogen cycle that simulates how nitrogen moves through the ecosystem;

  3. Simulation of nitrous oxide and methane emissions;

  4. An interface for configuring model structure.


These improvements allow SIPNET to represent the water, carbon, and nitrogen cycles of managed ecosystems while also making it easier to configure and extend the model. SIPNET now supports analysis of land management and climate change impacts on the greenhouse gas balance of ecosystems.
