Plot esimtated evapotranspiration with climate variables

Produce plot of daily, monthly and annual averaged estimated evapotranspiration with selected climate variables of the same time step.

Keywords
plot, climate, evapotranspiration, forcing
Usage
ETForcings(data, results, forcing)
Arguments
data

A list of data named data which must contain a component with the name of a climate variable that the estimated evapotranspiration should be plotted against, see forcing.

results

A list named results which has been derived from function ET.

forcing

A character string as the name of a climate variable that the estimated evapotranspiration should be plotted against, can be any of: Tmax - maximum temperature, Tmin - minimum temperature, u2 - average wind speed at 2m, uz - average wind speed, Rs - solar radiation, n - daily sunshine hours, Precip - precipitation, Epan - Class-A pan evaporation, RHmax - maximum relative humidity, RHmin - minimum relative humidity, Tdew - average dew point temeprature.

Value

Three plots are generated for the response of calculated evapotranspiration to each climate variable, including: 1) daily evapotranspiration estimate vs. daily average temperature; 2) monthly mean daily evaporationion estimate vs. monthly average temperature; 3) annual mean daily evaporationion estimate vs. annual average temperature.
