priestley_taylor {evapoRe}R Documentation

Calculate Potential Evapotranspiration (PET) using Priestley-Taylor Method

Description

The function priestley_taylor computes PET by Priestley-Taylor method.

Usage

priestley_taylor(tavg, rn, elevation = NULL, pres = NULL, x = NULL)

## S4 method for signature 'missing,missing,missing,missing'
priestley_taylor(x)

## S4 method for signature 'Raster,Raster,ANY,ANY'
priestley_taylor(tavg, rn, elevation = NULL, pres = NULL, x = NULL)

## S4 method for signature 'character,character,ANY,ANY'
priestley_taylor(tavg, rn, elevation = NULL, pres = NULL, x = NULL)

Arguments

tavg

Raster* object or file path; average temperature (°C)

rn

Raster* object or file path; net radiation (MJ m-2 day-1)

elevation

Raster* object or file path; elevation (m). Optional if 'pres' is provided.

pres

Optional. Raster* object or file path; atmospheric pressure (kPa)

x

A 'data.table' with columns: "lon", "lat", "date", "tavg", "rn", and either "elevation" or "pres".

Details

For Raster inputs, provide raster objects or file paths for 'tavg', 'rn', and either 'elevation' or 'pres'. For 'data.table' input, provide a single 'data.table' with columns: "lon", "lat", "date", "tavg", "rn", and either "elevation" or "pres".

Value

RasterBrick or data.table of PET values (mm/day)
