Abstract

The overall goal of this collection is to provide the hydrologic modelers with the datasets and an end-to-end workflow to explore the sensitivity of hydrologic model simulations to variability in the characteristics of meteorological forcings that is further described in the research paper, Van Beusekom et al. (2021). In this paper, hydrological outputs from the SUMMA model for the 671 CAMELS catchments across the contiguous United States (CONUS) are investigated to understand their dependence on input forcing behavior across CONUS. The paper lays out a simple methodology that can be applied to understand the relative importance of seven model forcings (precipitation rate, air temperature, longwave radiation, specific humidity, shortwave radiation, wind speed, and air pressure).

This collection includes three resources which help the modelers to reproduce and build on the results from the paper.

1- First resource, provides the entire NLDAS forcing datasets used in the paper.

2- Second resource provides an end-to-end workflow of CAMELS basin modeling with SUMMA for the paper simulations configured for execution in connected JupyterHub compute platforms. This resource is well-suited for a smaller scale exploration of the paper goal: explores the paper goal mentioned above for one example CAMELS site and a period of 18-month simulation to only demonstrate the capabilities of the notebooks.

3- Third resource, however, uses HPC (High-Performance Computing) through CyberGIS Computing Service to address the same goal as the second resource. The HPC enables a high-speed running of simulations which makes it suitable for running larger simulations (even as large as the entire 671 CAMELS sites and the whole 60-month simulation period used in the paper) practical and much faster than the second resource.

Greater details can be found in each resource.
