hargreaves_samani {evapoRe}R Documentation

Calculate Potential Evapotranspiration (PET) using Hargreaves-Samani method

Description

The function hargreaves_samani computes PET using the Hargreaves and Samani method.

Usage

hargreaves_samani(tavg, tmax, tmin, x = NULL)

## S4 method for signature 'Raster,Raster,Raster'
hargreaves_samani(tavg, tmax, tmin, x = NULL)

## S4 method for signature 'character,character,character'
hargreaves_samani(tavg, tmax, tmin, x = NULL)

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

Arguments

tavg

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

tmax

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

tmin

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

x

A 'data.table' with columns: "lon", "lat", "date", "tavg", "tmin", "tmax".

Details

For Raster inputs, provide raster objects or file paths for average ('tavg'), maximum ('tmax'), and minimum ('tmin') temperature. For 'data.table' input, provide a table with columns: "lon", "lat", "date", "tavg", "tmin", and "tmax".

Value

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