For convenience, the evaporation module defines a class for the comparison of different PET models for a given site.
Bases: object
A holdall class for the comparison of PET estimates.
The PET models listed in the models are all evaluated from the series of input temperatures tmin and tmax, for the given latitude.
Parameters:  tmin : TimeSeries
tmax : TimeSeries
latitude : float
rain : TimeSeries, optional
%(Kt)s : %(models)s : %(reference)s : 

Methods
RMSE  
RMSE_per_period  
kendalltau  
monthly_average  
spearmanr
