Dummy for generic function, no need to define. |
This formulation provides a single calculation method with no alternatives available.
The function prints a calculation summary to the screen containing the following elements:
- ET model name and ET quantity estimated
- Time step of the output ET estimates (i.e. the value of argument ts
)
- Units of the output ET estimates
- Time duration of the ET estimation
- Number of ET estimates obtained in the entire time-series
- Basic statistics of the estimated ET time-series including mean, max and min values.
The function also generates a list containing the following components, which is saved into a csv
file named as ET_McGuinnessBordne.csv in the working directory:
ET.Daily |
Daily aggregated estimations of McGuinness-Bordne potential evapotranspiration. |
ET.Monthly |
Monthly aggregated estimations of McGuinness-Bordne potential evapotranspiration. |
ET.Annual |
Annually aggregated estimations of McGuinness-Bordne potential evapotranspiration. |
ET.MonthlyAve |
Monthly averaged estimations of daily McGuinness-Bordne potential evapotranspiration. |
ET.AnnualAve |
Annually averaged estimations of daily McGuinness-Bordne potential evapotranspiration. |
ET_formulation |
Name of the formulation used which equals to |
ET_type |
Type of the estimation obtained which is |
