iLand model logic is documented in a growing number of linked Wiki pages (currently >120 pages, containing more than 300 reference-hyperlinks to the scientific literature that model development is based on), in an effort to defying the 'black box' character sometimes inherent in simulation modeling.
The documentation pages are currently only available to the core model developers, until major parts of the model are published in the peer-reviewed scientific literature. So check back regularly for updates, and don't hesitate to contact us if you have questions.
