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

建立了一个即使在网格和半干旱地区也可以在没有土壤水分信息的情况下估算区域蒸发量的模型。为了验证模型的有效性，在西伯利亚泰加森林、西伯利亚冻原地区、西藏、泰国复杂地表观测到的蒸发量，将世界上一个面积为200-300千米^2的流域的集水区水量平衡估算的蒸发量与模型的年蒸发量进行比较。结果表明，两者具有很好的一致性。然而，对日蒸发量的进一步调查显示，这种一致性并不总是好的。泰国数据给出了较好的结果，而西伯利亚数据和蒙古数据没有产生较好的结果。因此，总而言之，模型能够在长于月的时间尺度上估计蒸发量，而在每天的基础上，成功与否取决于地点和条件

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
