The purpose of this repo is to collect code(s) to compute evaporation/evapotranspiration (eo) using several approaches. Although many packages exists, I believe that is better to code it by yourself (as a way of learning and understanding these complex equations).

By the time, two approaches for reference eo are available:

• FAO56 Penman-Monteith
• Hargreaves-Samani

I expect to add many more (see Xiang et al. 2020)
