The Nanxiaohegou watershed is located on the edge of Dongzhiyuan in Xifeng District, Qingyang City, Gansu Province. It is a ditch on the left bank of the Pu River, a tributary of the Jing River, with a drainage area of 36.3km ²， At an altitude of 1050-1423m, it has typical geomorphic features of loess plateau and gully areas, mainly consisting of three major geomorphic units: plateau, slope, and gully. Gully density 2.68km/km ²， The average slope of the ditch is 2.8%. This dataset includes daily water surface evaporation at three evaporation observation points in the watershed, including Yangjiagou, Dongzhuanggou, and Shiba Mu Tai. The meteorological park in Nanxiaohegou covers an area of 625m ²， All instruments and equipment are powered by solar energy; The main observation contents include: wind direction, wind speed, temperature, humidity, air pressure, evaporation, rainfall, soil temperature, soil humidity, and total radiation
