  # 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. All data have to given without missing values. Exception: relative humidity and wind speed. The value -999.9 indicates that a measurement value is not available. In this case, missing values were replaced by 1013 hPa for relative humidity and 0.5 m/s for wind speed. 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

  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.
