Description

The function abtew computes PET by Abtew method

Usage

abtew(tavg, rs, x = NULL)

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

## S4 method for signature 'Raster,Raster'
abtew(tavg, rs, x = NULL)

## S4 method for signature 'character,character'
abtew(tavg, rs, x = NULL)

Arguments

tavg

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

rs

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

x

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

Details

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

Value

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