hydromt.workflows.forcing.pet_debruin(temp, press, k_in, k_ext, timestep=86400, cp=1005.0, beta=20.0, Cs=110.0)[source]#

Determine De Bruin (2016) reference evapotranspiration.

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, default 86400) – seconds per timestep
cp (float, default 1005.0) – standard cp [J kg-1 K-1]
beta (float, default 20.0) – correction constant [W m-2]
Cs (float, default 110.0) – emperical constant [W m-2]

Returns:

pet – reference evapotranspiration

Return type:

xarray.DataArray
