Priestley-Taylor potential evapotranspiration

Calculates the potential evapotranspiration using the implementation by Davis et al (2017), based on Priestley & Taylor (1972)

pet(netrad, tc, patm, return_df = FALSE)

Arguments

netrad

Net radiation (W m-2)

tc

Air temperature in degrees Celsius

patm

Atmospheric pressure (Pa)

return_df

A logical specifying whether to return a data frame with a single column containing potential evapotranspiration. Defaults to FALSE

Details

Potential evapotranspiration (mm s-1)
