The Nanxiaohegou watershed is located on the edge of Dongzhiyuan in Xifeng District, Qingyang City, Gansu Province. It is a tributary of the Jinghe River on the left bank of the Puhe River, with a drainage area of 36.3km ² and an elevation 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. The density of gullies is 2.68 km/km ², and the average gradient of gullies is 2.8%. This dataset includes the daily water surface evaporation at three evaporation observation points, Yangjiagou, Dongzhuanggou, and Shibamutai, within the watershed. The meteorological park in Nanxiaohegou covers an area of 625m ², and all instruments and equipment are powered by solar energy; The main observation contents include: precipitation, evaporation, environmental temperature, environmental humidity, wind speed, wind direction, soil temperature, soil humidity, air pressure, total radiation, photosynthetic radiation, ultraviolet radiation, illuminance, and carbon dioxide
