SnowClim: Present Snow Data

This resource contains snow metrics for the present-day period and represents a subset of the SnowClim Dataset (https://www.hydroshare.org/resource/acc4f39ad6924a78811750043d59e5d0/). The SnowClim Dataset was developed following the methods presented in Lute et al., (in prep). The present-day snow data was created by first downscaling 4 km climate forcings from the Weather Research and Forecasting (WRF) model (Rasmussen and Liu, 2017) over a thirteen year period (1 Oct 2000 to 30 Sep 2013) and then using this climate data to force the SnowClim snow model. Snow model outputs were summarized into snow metrics at ~210 m spatial resolution for the western US.

Additional details about forcing data preparation, model physics, model calibration, and application to the western US domain can be found in:

本资源包含了现代时期的积雪指标数据，并代表了 SnowClim 数据集（https://www.hydroshare.org/resource/acc4f39ad6924a78811750043d59e5d0/）的一个子集。SnowClim 数据集是根据 Lute 等人（待发表）提出的方法开发的。现代积雪数据首先通过将 4 公里气候强迫因子从 Weather Research and Forecasting (WRF) 模型（Rasmussen 和 Liu，2017）在十三年期间（2000 年 10 月 1 日至 2013 年 9 月 30 日）进行降尺度处理，然后利用这些气候数据驱动 SnowClim 积雪模型。积雪模型输出的结果被汇总为约 210 米空间分辨率的积雪指标，用于美国西部地区。有关强迫数据准备、模型物理机制、模型校准以及在美国西部地区应用等方面的详细信息，可参考以下文献：Lute, A. C., Abatzoglou, J., 和 Link, T.：SnowClim v1.0：美国西部地区的高分辨率积雪模型与数据，地球科学模型发展，15，5045–5071，https://doi.org/10.5194/gmd-15-5045-2022，2022。
