Description of output-files

Daily Output

Daily output variables are the state variables valid at the actual day.
Naming of the output file as follows

<sitename>_<var>.out<anz_sim>

with:

<sitename> location name
<var> content description
<anz_sim> number of simulation

example: site1_day.out2 daily output of several scalars of water and C/N balance at location site1 from the second simulation run

Daily output for cohorts is decribed in the chapter cohort outputs.

The following tables give an overview of the name and contents of the output files with daily data
