%X From June 10, 2011 to September 2, 2011, the data of pan evaporation were observed at 3100m grassland meteorological station in tianlaochi watershed of Qilian Mountain. The observation instrument of grassland weather station is a 20cm evaporating dish, a 20cm diameter and 10cm high metal round basin with a knife edge. In order to prevent birds and animals from drinking water, a trumpet shaped wire mesh ring is set on the upper part of the mouth of the basin. When measuring, put the instrument on the shelf, the mouth of the instrument is 70cm above the ground, and put in a fixed amount of water every day. After every 24 hours, measure the remaining water in the cup, and the reduced water is the evaporation.The data are daily evaporation from June 10, 2011 to September 2, 2011.
