I want to ask about the process of calculating the Evapotranspiration in ecoroof. The amount of evapotranspiration in the simulation results is much higher than the rainfall amount, considering the irrigation was off in the simulation. Even when I removed the rainfall data we still have Evapotranspiration and moisture in the soil. I want to ask where this amount of water comes from without having rainfall and irrigation? is it absorbed from the surrounding humidity? Thanks in advance.
