本文回顾了限制我们目前陆地水文循环知识的概念问题。我们的出发点是，为了理解水文循环，我们需要进行观测，并开发动态模型来概括我们的理解。然而，无论是观测还是模型都无法全面描述水文循环。数据同化结合了观测和模型信息，增加了模型和观测的价值，产生了越来越一致和完整的水文组成部分估计数。在这篇评论文章中，我们提供了一个历史的概念问题的角度来看，并讨论国家的最先进的水文观测，建模和数据同化系统。
This paper reviews the conceptual problems limiting our current knowledge of the hydrological cycle over land. We start from the premise that to understand the hydrological cycle we need to make observations and develop dynamic models that encapsulate our understanding. Yet, neither the observations nor the models could give a complete picture of the hydrological cycle. Data assimilation combines observational and model information and adds value to both the model and the observations, yielding increasingly consistent and complete estimates of hydrological components. In this review paper we provide a historical perspective of conceptual problems and discuss state-of-the-art hydrological observing, modelling and data assimilation systems.
