ABSTRACT:

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.

Additional details regarding the SnowClim model physics and application to the western US are available in:
Lute, A.C., Abatzoglou, J.T., and T. Link. “SnowClim v1.0: high resolution snow model and data for the western United States.” Submitted to Geoscientific Model Development.

ABSTRACT:

The SnowClim Model and Dataset address the need for climate and snow data products that are based on physical principles, that are simulated at high spatial resolution, and that cover large geographic domains.

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 throughout several empirical simplifications. The model code can be downloaded or run in the cloud using MATLAB Online through HydroShare.

The SnowClim Dataset consists of climate forcing data for and snow outputs from the SnowClim Model. Climate forcing data was downscaled from 4 km climate data from the Weather Research and Forecasting (WRF) model (Rasmussen and Liu, 2017) to ~210 m across the contiguous western United States. Climate forcings were downscaled from WRF directly for a present day (2000-2013) period and a thirteen year pseudo global warming scenario reflecting conditions between 2071-2100 under RCP 8.5. Climate forcings were prepared for a third time period by perturbing present-day downscaled climate data by the multi-model mean from CMIP5 to reflect conditions under pre-industrial conditions (1850-1879).

Additional details regarding the SnowClim model physics, model calibration, climate data downscaling, model application to the western US, and model performance are available in:

ABSTRACT:

This resource is part of the larger SnowClim Dataset (https://www.hydroshare.org/resource/acc4f39ad6924a78811750043d59e5d0/). This resource contains pre-industrial climate metrics. Climate metrics were created by first downscaling outputs of the Weather Research and Forecasting Model (WRF; Rasmussen and Liu, 2017) for the present-day period (1 Oct 2000 to 30 Sep 2013) using a combination of local lapse rates and terrain corrections for solar radiation as described in Lute et al., (in prep). Downscaled data was then perturbed by the multi-model mean delta from CMIP5 to create climate date reflecting pre-industrial conditions (1850-1879). Climate metrics are available on a ~210 m grid for the western United States in both netCDF and GeoTiff formats.

Additional information is available in:

This resource contains snow metrics for the pre-industrial 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).

This climate data was then used to force the SnowClim snow model. Snow model outputs were summarized into snow metrics at ~210 m spatial resolution for the western US.
