超分辨率地表模型可以明确地表示景观尺度的异质性,但表示更精细尺度过程和满足计算需求的复杂性使其无法为一般科学界所接受,并限制了其采用。在这项工作中,我们提出了多层冠层和三维土壤(MLCan3D)模型,这是一个高分辨率,高保真,旨在保持可达性的物理生态水文模型。MLCan3D实现了详细的物理过程表示,可通过图形用户界面访问,并通过与其他模型和现场数据的比较进行了测试。这项工作证明了使用MLCan3D产生接近真实系统的模拟的可行性,以及该模型进行虚拟实验以探索模型结果的潜力。我们的目标是让MLCan3D成为一个虚拟实验室,使更广泛的科学界的虚拟实验成为可能,并有助于我们理解生态水文过程的异质性、动态和跨尺度的相互作用。
Hyper-resolution land surface models can explicitly represent landscape scale heterogeneity, but the complexity of representing finer scale processes and meeting computational needs makes them inaccessible to the general scientific community and limits their adoption. In this work, we present the Multi-layer Canopy and 3D Soil (MLCan3D) model, which is a high resolution, high fidelity, physical ecohydrologic model that aims to maintain accessibility. MLCan3D implements detailed physical process representations, is accessible through graphical user interface, and is tested using comparisons with other models and field data. This work demonstrates the feasibility of using MLCan3D to produce simulations close to real systems and the potential of the model to perform virtual experiments to explore model results. Our goal is for MLCan3D to serve as a virtual laboratory that enables virtual experiments from the broader scientific community and contribute to our understanding of ecohydrologic process heterogeneity, dynamics, and interactions across scales.
