hydromt.stats.skills.volumetric_error(sim, obs, dim='time')[source]#

Return the volumetric error between two time series.

$$\begin{gathered} \begin{array}{r}VE=1-\\ frac \\ su{m}_{i=1}^N(|si{m}_i-ob{s}_i|) \\ su{m}_{i=1}^N(ob{s}_i)\end{array} \end{gathered}$$

Parameters:

• sim (xarray DataArray) – simulations time series

• obs (xarray DataArray) – observations time series

• dim (str, optional) – name of time dimension in sim and obs (the default is ‘time’)

Returns:

volumetric error

Return type:

xarray DataArray
