Description of input files

Site depending data files

Litter initialization file

recommended extension: .lit

The file contains the initialization of the litter compartments for each species in g C/m².
Data file starts without any mandatory leading line. Description lines of optional number are possible and have to start with ! as the first character.

Structure:   Initailization data for each species in the same order like the species parameter file and line by line for the litter compartments in the following order (with their names in the source code)

Foliage
(C_opm_fol)
Twigs and branches
(C_opm_tb)
Fine roots
(C_opm_frt)
Coarse roots
(C_opm_crt)
Stems
(C_opm_stem)

 

Example

Initialization of foliage, twigs and fine root pools of pine and oak and the pool of dead stems for pine and douglas fir.

In the above example, the initialization for all species is given in this file. Because the last initialization data is for douglas fir with the species number 10 (see line 5), it is sufficient to give the data in the following way

! litter initialisation  10 tree species g C/m²
