Abstract

Pan is used as an instrument of measuring the evaporation demand of atmospheric, and is widely used in hydrological and meteorological stations.In order to deeply understand the physical significance of pan evaporation, a field experiment "Inner Mongolia Pan Evaporation Experiment (IMPEEX)" is carried out in the arid region of northwest China.Based on the energy balance principle, the evaporation processes of Class A, 20 cm and E601B pans are measured minutely with micro-meteorological method.The observations results show that the diurnal variations of three types of pans evaporation processes have significant differences owing to the non-uniformity intensity between water body of pan and the surrounding environment.Temperature stratification of water in the pan is increasing with the depth of water.The heat flux between E601B pan water and around soil fluctuates between ±10 W·m-2, and the sum of this flux is almost 0 at daily time scale.The albedo of water surface of Class A pan is displays "U" type at sunny days, and the daily averaged albedo is 0.087.Energy balance of water of pans analysis shows that the solar radiation and water thermal storage rate are the main two components of energy which control the pan evaporation, the sensible heat flux at water surface and heat conduction through pan wall and bottom are subordinate components.
