# Site depending data files Climate data file *.cli: time series of climate variables, site dependent Soil parameter file *.sop: soil parameter, site dependent Stand initialization file *.ini: initialization of a stand, site dependent Climate data file Recommended extension: .cli Two alternatives to import climate data are realized: Original DWD-data with 12 climate parameters in daily resolution, from which the most essential (see example) are chosen, and the reduced data files only with the required parameters (recommended extension .cli) will be imported. If such a reduced file doesn’t exist yet, it can be created when importing a DWD-file. Already intended is the adoption of a weather generator for the data with monthly temporal resolution. Example for climate data set: site1.cli (day/ month/ year/ average temperature [°C]/ humidity [%]/ rainfall [mm]/ air pressure [hPa]/ solar radiation [J/cm²]) 1 1 1951 -3.8 83.0 1.5 989.5 297.0 2 1 1951 -2.5 92.0 0.0 985.6 209.0 3 1 1951 -0.2 85.0 0.0 993.1 142.0 4 1 1951 0.6 82.0 0.01005.5 199.0 5 1 1951 2.4 92.0 4.81000.8 158.0 6 1 1951 4.4 99.0 1.9 998.4 36.0 7 1 1951 5.4 75.0 1.1 991.4 48.0 8 1 1951 3.9 85.0 0.7 999.8 94.0 Example for climate data set type DWD: (day/ month/ year/ max. temperature [°C]/ mean temperature [°C]/ minimum temperature [°C]/ precipitation [mm]/ relative humidity [%]/ air pressure [hPa]/ water vapour pressure [hPa]/ sunshine duration [h]/ cloudiness/ radiation [J/cm²]/ wind speed [m/s]) The value -999.9 indicates that a measurement value is not available. d m year tmax tmean tmin pcp hum AirP dadr sunsh cloud rad wind 01 01 1960 30.5 24.7 20.6 9.8 68.3 948.6 -999.9 -999.9 -999.9 1914.4 2.8 02 01 1960 27.3 23.8 20.9 16.2 77.6 948.0 -999.9 -999.9 -999.9 1403.8 2.2 03 01 1960 25.9 22.3 19.3 10.8 84.0 950.3 -999.9 -999.9 -999.9 1215.1 2.0 ### Site and soil parameter file recommended extension: .sop Describing lines that start with ! will be read over. The data will be imported line by line, the following description starting with ! serves only the purpose for a better understanding of the file construction. The number, denoted in nlay , has to agree with the number of layers for which data are being imported. After the layer based data no further data from this fileare being imported. All other potentially existing lines only serve as information. ! Kienhorst 13.38 ! Latitude 52.58 !

Descriptive lines starting with ! are being read over. In each data line there are there are values for one cohort. An arbitrary amount of cohorts can be declared. The data file is being created by an initialization routine. It is possible to write initializations for multiple sites in one file, whereas the selection of the current site happens through the stand identifier (stand_id) in the control file. 1 1000. ! = volume function, patch size ! data source= S source file= input/xxxxx.prn ! sapwood fraction and form factor now dynamic per cohort ! 4C Tree Initialization File (Stand) ! ! contains the following data (single tree values): ! ! x_fol: foliage biomass (kg) ! x_frt: fine root biomass (kg) ! x_sap: sapwood biomass (kg) ! x_hrt: heartwood biomass (kg) ! x_Ahb: cross sectional area of heartwood at stem base (cm**2) ! height: tree height (cm) ! x_hbole: bole height (cm) ! x_age: tree age (years) ! n: number of trees ! sp: species (integer number) !
