pet_priestley_taylor: Potential Evapotranspiration

In ECA-D/PETr: PET

Description

This function takes a dataframe object as input and computes PET using Makkink's method.

Usage

pet_priestley_taylor(indat)

Arguments

indat

= dataframe containing the input variables

Value

A vector containing the daily Potential EvapoTranspiration (mm/day)

Examples

pet_priestley_taylor(indat)

Where the dataframe "indat" contains the following variables:

tmin  = Temperature min    (degrees Celsius)
tmax  = Temperature max    (degrees Celsius)
only one of the following variables (vp OR rh OR dp) are to be passed
vp  = Vapour pressure    (hPa)
rh =  Relative humidity  (%)
dp =  Dewpoint           (degrees Celsius)
rs  = radiation          (MJ/m^2)
Also rquired is the latitude and longitude (for land sea mask)
lat = Latitude  (degrees)
lons = Longitude (degrees)

Missing values should be converted to NA
