Evaluation of three energy balance-based evaporation

The heat storage changes (Q t) can be a significant component of the energy balance in lakes, and it is important to account for Q t for reasonable estimation of evaporation at monthly and finer timescales if the energy balance-based evaporation models are usedHowever, Q t has been often neglected in many studies due to the lack of required water temperature data.
