We have already indicated that temperature impacts ET through its impact on VPD and advection. In addi-tion to these factors temperature impacts ET is some more subtle ways. When all other factors are equal, ET will be higher for warm as compared to cool vegetation, This evapotranspiration capacity depends on multiple factors such as the amount of available water, the types of plants and substrates as well as the orientation and sun exposure, among others (Perini et al., 2017). Also, the climate conditions are highly influencing, since in dry environments or windy conditions evapotranspiration will increase..
