Talsim-NG offers multiple options for entering/calculating potential evaporation:

• Specification of an external time series with values for the potential evaporation
• Internal calculation of potential evaporation: the potential evaporation can be calculated internally based on temperature and, depending on the method, additional parameters. The following methods are available:
  • Penman: requires the specification of average patterns or of time series for sunshine duration, wind speed and relative humidity
  • Haude: requires the specification of average patterns or of a time series for relative humidity
  • Turc: requires the specification of average patterns or of time series for sunshine duration and relative humidity
  • Blaney-Criddle: simplistic method requiring only the specification of a latitude which is used internally to derive the sunshine duration.
• Specification of a fixed evaporation rate per year: when using this option, the entered annual value is distributed inner-annually using the compensation function according to Brandt (see below).
