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)
