Download and support of Yasso

Software and computer source code are available for using Yasso15 and Yasso07 models. The Yasso user-interface software is an easy way to try and explore the model. It is also useful for simple model applications.

All work referrring to Yasso15, Yasso07 or Yasso or the results of these models should cite the papers that describe the appropriate model version. References to these papers are found in the beginning of the Publications of Yasso page.


We are currently finding out about appropriate ways and conditions of making Yasso15 user-interface software and source code available. For now, please request the software and the source code from Jari Liski.
