- Parameters:
temp (
xarray.DataArray
) – DataArray with temperature [°C]press (
xarray.DataArray
) – pressure at surface [hPa]k_in (
xarray.DataArray
) – global (=short wave incoming) radiation [W m-2]k_ext (
xarray.DataArray
) – TOA incident solar radiation [W m-2]timestep (
int
, default86400
) – seconds per timestepcp (
float
, default1005.0
) – standard cp [J kg-1 K-1]beta (
float
, default20.0
) – correction constant [W m-2]Cs (
float
, default110.0
) – empirical constant [W m-2]
- Returns:
pet – reference evapotranspiration
- Return type:
