Calculates the temperature of air at hub height.
The temperature is calculated using the method specified by the parameter temperature_model.
Parameters: weather_df (pandas.DataFrame) – DataFrame with time series for temperature temperature in K. The columns of the DataFrame are a MultiIndex where the first level contains the variable name (e.g. temperature) and the second level contains the height at which it applies (e.g. 10, if it was measured at a height of 10 m). See documentation of
ModelChain.run_model()for an example on how to create the weather_df DataFrame.
Returns: Temperature of air in K at hub height. Return type: pandas.Series or numpy.array
If weather_df contains temperatures at different heights the given temperature(s) closest to the hub height are used.
