  # 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 There are several options to import climate data. The value -999.9 indicates that a measurement value is not available. Mandatory extension: .cli 1. Version Data file starts without any mandatory leading line. Description lines of optional number are possible and have to start with ! as the first character. Following data lines contain daily values of meteorological data and are compiled as follows:
  Position | description | unit
  1 | date as dd.mm.jjjj | -
  2 | mean air temperature | °C
  3 | relative humidity | %
  4 | precipitation | mm
  5 | atmospheric pressure | hPa
  6 | global radiation | J/cm²
  7 | wind speed | m/s
  Examples for climate data set *.cli without any mandatory leading line 2. Version First line of data file starts with N. After the first line description lines of optional number are possible and have to start with ! as the first character. Following data lines contain daily values of meteorological data and are compiled as follows: Date is given without any point
  Position | description | unit
  1 | day | -
  2 | month | -
  3 | year | -
  4 | mean air temperature | °C
  5 | relative humidity | %
  6 | precipitation | mm
  7 | atmospheric pressure | hPa
  8 | global radiation | J/cm²
  9 | wind speed | m/s
  Examples for climate data set *.cli with leading line starting with N 3. Version First line of data file starts with T. After the first line description lines of optional number are possible and have to start with ! as the first character. Following data lines contain daily values of meteorological data and in addition to 1.version maximum and minimum air temperature. The data lines are compiled as follows:
  Position | description | unit
  1 | date as dd.mm.jjjj | -
  2 | mean air temperature | °C
  3 | relative humidity | %
  4 | precipitation | mm
  5 | atmospheric pressure | hPa
  6 | global radiation | J/cm²
  7 | wind speed | m/s
  8 | maximum air temperature | °C
  9 | minimum air temperature | °C
  Examples for climate data set *.cli with leading line starting with T Mandatory extension: .txt First line of data file starts with any line and is being read over. Following data lines contain daily values of eight meteorological data and are compiled as follows: Date is given in another order Only one line with any description is mandatory.
  Position | description | unit
  1 | year (jjjj) | -
  2 | month | -
  3 | day | -
  4 | maximum air temperature | °C
  5 | mean air temperature | °C
  6 | minimum air temperature | °C
  7 | precipitation | mm
  8 | relative humidity | %
  9 | athmospheric pressure | hPa
  10 | global radiation | J/cm²
  11 | wind speed | m/s
  Examples for climate data set *.txt Recommended extension: .dat The extension of the filename is arbitrary, but different from cli and txt. The data can start immediately or with a heading line starting with ta. The data lines contain daily values of eleven meteorological data and are compiled as follows: Date is given without any point No description line is allowed.

Examples for climate data set *.dat Already intended is the adoption of a weather generator for the data with monthly temporal resolution. ### Site and soil parameter file recommended extension: .sop 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. First lines describe site conditions following by the information of soil layers. 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 file are being imported. All other potentially existing lines only serve as information. ### Stand initialization data file recommended extension: .ini Contains data for a start inventory. In each data line 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.
