Investigation into the distribution of surface energy balance over the Asia and Eurasia Continent

建立了一个不需要土壤湿度信息的区域蒸发估算模型，即使在网格和半干旱地区也能进行。为了检验该模型的有效性，我们将在西伯利亚的针叶林、西伯利亚的苔原地区、西藏、泰国的复杂地表观测到的蒸发量与世界上一个面积为200-300 km ^[2]的选定流域的集水平衡估算的蒸发量与模型推导的蒸发量进行了比较。结果表明，一个非常好的协议。然而，进一步的调查与日蒸发量的基础上显示，协议并不总是好的。泰国数据给出了一个很好的结果，而西伯利亚数据和蒙古数据没有产生好的结果。因此，总而言之，一个模型能够在一个月以上的时间尺度上估计蒸发，而在日常基础上，成功取决于位置和条件

A model has been created to estimate regional evaporation without the information of soil moisture even in an grid and semi-arid region. To check the validity of the model, observed evaporation at a taiga forest in Siberia, at tundra region of Siberia, at Tibet, complex surface of Thailand, evaporation estimated by a catchment water balance in a selected watershed in the world that has the area of 200-300 kms^2 was compared against the model derived evaporation on annual basis. The result indicates a very good agreement. However, a further investigation with daily evaporation bas revealed that agreement is not always good. Thailand data gave a good result, while Siberia data and Mongolian data did not produce as good result. Thus in summary, a model is capable of estimating evaporation on a time scale longer than month, while on daily basis a success depends on a location and condition
