Basin Geometry and Mountain Snowpack Responses to Climate Change: Data, Code, and Figures

GeoNetwork record: www.gwfnet.net/geonetwork/srv/eng/catalog.search#/metadata/6032b57a-0dad-473d-bbf2-42f98b2e3426

This dataset contains the code and data files needed to produce the analyses and figures in Shea et al. (2021), doi:10.3389/frwa.2021.604275. The data used in this study are derived from publicly available data sets. These include global elevation data, river basin boundaries, climate normals, automated snow pillows, and manual snow course observations. The Cold Regions Hydrological Model (CRHM, v.05/15/19) was used to produce daily estimates of snowmelt for 50 basins using identical elevation ranges and bands, identical accumulation gradients, and identical climate inputs. Only the hypsometry (area-elevation distribution) was varied for each model run. Analysis of hypsometry, climate inputs, and CRHM outputs is given in a Jupyter notebook running Python 3.7.6.

This dataset supports the Global Water Futures project.

CODE-SPECIFIC INFORMATION FOR: BasinHypsometryCRHM-Final.ipynb
-----------------------------------------------------------------

1. Brief description of the code:

Jupyter notebook does the following:
- calculates and clusters basin hypsometries
- assesses the skill of simple linear accumulation gradients and synthetic temperatures against observational data
- imports results of the CRHM model runs to assess snow pack and snow melt responses to increased temperatures
- produces figures contained in the Shea et al. (2021) publication
