%X This data set is the daily water surface evaporation of Yangjiagou, dongzhuanggou and 18 Mu stations in Nanxiaohegou basin from 1991 to 2000. The model of evaporation observation instrument is HY.AM3 The diameter of the dish is 20cm, and the observation accuracy is 0.1mm. It was observed at 8 o'clock every day and every five days during the freezing period. The evaporation capacity of evaporating dish is observed by rainfall cup of the same specification or special platform scale. The original water in the evaporating dish is 20 mm. At 8:00 a.m. of the previous day, the water in the cup is filled with 20 mm. After 24 hours, the remaining water in the dish is returned to the measuring cup, and the amount of reduction is the evaporation of the day.
