ETo - A Python package for calculating reference evapotranspiration

The ETo package contains a class and associated functions to calculate reference evapotranspiration (ETo) using the UN-FAO 56 paper [1]. Additional functions have been added to calculate historic ETo or potential evapotranspiration (PET) for comparison purposes.

The GitHub repository is found here

A parameter estimation function has also been added to the base class to convert most any variety of metereological parameter inputs to the necessary parameters needed to calculate ETo. Unit conversion has not been implemented yet, so make sure you use the correct units!
