Water surface evaporation observation is an important component of hydrological element observation.Traditional instrument measurement methods require manual recording of water level changes,precipitation,and overflow in the evaporator on time,in order to obtain evaporation.The Mingguang Hydrological Station has introduced the FFZ-03 fully automatic digital water surface evaporator,which adopts an active quantitative water suction working mode to improve measurement accuracy.Based on the one-year comparison data of the station,error analysis method was used to compare and analyze the evaporation data collected automatically by the evaporator with the manually observed data.The results show that the monitoring results of the digital water surface evaporation equipment have a good correlation with the manually observed values,indicating that the overall observation results are reliable and meet the accuracy requirements of the water surface evaporation observation specifications.
