SnowClim Model

The SnowClim Model is a physics-based snow model that incorporates key energy balance processes necessary for capturing snowpack spatiotemporal variability, including under future climate scenarios, while optimizing computational efficiency through several empirical simplifications. The SnowClim Model is specifically designed for energy balance snow modeling at high spatial resolutions over large domains.

The model is written in MATLAB (R2020b). The model code can be downloaded below or run in the cloud through HydroShare by clicking the 'Open With' button above and selecting MATLAB Online. The code run_snowclim_model.m describes how to set parameters, import climate forcing data, run the model, and plot a few model outputs. This code uses default parameter values and the example climate forcing data found in /example_forcings but can be modified for new applications.

SnowClim模型（SnowClim Model）是一款基于物理原理的积雪模型，其纳入了捕捉积雪时空变异性所需的核心能量平衡过程——包括未来气候情景下的积雪变异性——同时通过多项经验性简化手段优化了计算效率。该模型专为大区域范围内高空间分辨率的能量平衡积雪模拟而设计。

该模型采用MATLAB（R2020b）编写。模型代码可在下方下载，或通过HydroShare云端运行：点击上方的“打开方式”按钮并选择MATLAB Online即可。脚本run_snowclim_model.m详细说明了如何设置参数、导入气候强迫数据、运行模型以及绘制部分模型输出结果。该脚本采用默认参数值与/example_forcings目录下的示例气候强迫数据，也可针对新的应用场景进行修改。
