What is an assumption in the CBM-CFS3 and how is it used?
There are ten assumption types in the CBM-CFS3: Simulation, Climate, Disturbance and Management, Disturbance Matrices, Growth and Yield, Biomass Turnover, Stand Initialization, CBM Run, DOM Turnover, and Volume-to-Biomass assumptions. When users create a project, a default assumption is created for each of these assumption types. The default assumptions created are essentially names linked to either the user’s imported data or data assigned to the user’s project based on the administrative and ecological zone they select during data import. For example, imported growth and yield curves would be linked to the default growth and yield assumption. Users can also create their own assumptions and link them to new data that they enter into their project in the CBM-CFS3. A project must have at least one assumption of each type in order to be run in a simulation. As discussed, one assumption of each type is created by default whenever users create a project, so that they may proceed immediatel
