How did you initialize your model, e.g. using individual tree dbh and height or stand basal area? how do you initialize soil conditions?: number of trees per diameter class, stand age
Which data from profound db did you use for initialisation (name of variable, which year)? from stand data or from individual tree data?: species, dbh_1_cm
Collelongo - year 1997
Solling beech and spruce - year 1967
Soro -year 1996
How is management implemented? e.g. do you harvest biomass/basal area proportions or by tree numbers or dimensions (target dbh)?: volume proportion
When is harvesting simulated by your model (start/middle/end of the year, i.e., before or after the growing season)?: at the beginning of the year
How do you regenerate? do you plant seedlings one year after harvest or several years of gap and then plant larger saplings?: Both can be used, but none was implemented in these simulations.
How are the unmanaged simulations designed? is there some kind of regrowth/regeneration or are the existing trees just growing older and older?: Regrowth is possible in the case of unmanaged development, but was not implemented in these simulations.
How are models implementing the noco2 scenario? please confirm that co2 is follwing the historical trend (based on profund db) until 2000 (for isimipft) or 2005 (for isimip2b) and then fixed at 2000 or 2005 value respectively?: They follow the historical trend until today
Does your model consider leap-years or a 365 calendar only? or any other calendar?: No leap years are considered in the model.
In hyytiälä and kroof, how did you simulate the "minor tree species"? e.g. in hyytiälä did you simulate only pine trees and removed the spruce trees or did you interpret spruce basal area as being pine basal area?: We did not simulate these plots because plots were not growing in the model.
How did you simulate nitrogen deposition from 2005 onwards in the 2b picontrol run? please confirm you kept them constant at 2005-levels?: Nitrogen deposition was not kept constant but increased based on the equation implemented in the model as a function of the calendar year (Kahn 1994)
What is the soil depth you assumed for each site and how many soil layers (including their depths) do you assume in each site? please upload a list of the soil depth and soil layers your model assumes for each site as an attachment (section 7).: Soil depth and number of soil layers are not used as an input in the model.
Is there any stochastic element in your model (e.g. in the management or mortality submodel) that will lead to slightly different results if the model is re-run, even though all drivers etc. remain the same?: yes, there is
What is the minimum diameter at which a „tree is considered a tree“? and is there a similar threshold for the minimum harvestable diameter?: 1 cm
Has your model been "historically calibrated" to any of the sites you simulated? e.g. has the site been used for model testing during model development?: No
Please upload a list of your parameters as an attachment (section 7). the list should include species-specific parameters and other parameters not depending on initialization data including the following information: short name, long name, short explanation, unit, value, see here for an example (http://www.pik-potsdam.de/4c/web_4c/theory/parameter_table_0514.pdf): http://etools.tuzvo.sk/sibyla/english/
