蒸散(evapotranspiration)是土壤蒸发和植物蒸腾的总称,即植被及地面整体向大气输送的水汽总通量，主要包括植被蒸腾、土壤水分蒸发及截留降水或露水的蒸发，作为能量平衡及水循环的重要组成部分，蒸散不仅影响植物的生长发育与产量，还影响大气环流，起到调节气候的作用。本数据为2000–2018年甘肃省蒸散发（ET）数据集，时间分辨率为8天，数据分辨率为1KM，数据格式为hdf。", "ds_source": "

Evapotranspiration is a general term for soil evaporation and plant transpiration, which refers to the total flux of water vapor transported by vegetation and the ground to the atmosphere. It mainly includes vegetation transpiration, soil water evaporation, and evaporation of intercepted precipitation or dew. As an important component of energy balance and water cycle, evapotranspiration not only affects plant growth and development and yield, but also affects atmospheric circulation, playing a role in regulating climate. This data is the evapotranspiration (ET) dataset of Gansu Province from 2000 to 2018, with a time resolution of 8 days, a data resolution of 1KM, and a data format of hdf.
