Water Balance Model Inputs and Outputs for the Conterminous United States, 1900-2015 This metadata record describes monthly input and output data covering the period 1900-2015 for a water-balance model described in McCabe and Wolock (2011). The input datasets are precipitation (PPT) and air temperature (TAV) from the PRISM group at Oregon State University. The model outputs include estimated potential evapotranspiration (PET), actual evapotranspiration (AET), runoff (RUN) (streamflow per unit area), soil moisture storage (STO), and snowfall (SNO). The datasets are arranged in tables of monthly total or average values measured in millimeters or degrees C and then multiplied by 100. The data are indexed by the identifier PRISMID, which refers to an ASCII raster of cells in an associated file named...

A limited amount of ancillary data, including location, physical watershed features, and basic water chemistry data for each site were also retained.

The three column format of comma-separated data can be readily joined to the comma-separated climate and water-balance variables described in the associated metadata file "Water Balance Model Inputs and Outputs for the Conterminous United States". Categories: Data; Types: Citation; Tags: Conterminous United States, climate change Warming and Implications for Water Supply in the Colorado River Basin Thehigh demand for water, the recent multiyear drought (1999–2007), andprojections of global warming have raised questions about the long-termsustainability of water supply in the southwestern United States. Inthis study, the potential effects of specific levels of atmosphericwarming on water-year streamflow in the Colorado River basin areevaluated using a water-balance model, and the results are analyzedwithin the context of a multi-century tree-ring reconstruction (1490–1998) ofstreamflow for the basin. The results indicate that if futurewarming occurs in the basin and is not accompanied byincreased precipitation, then the basin is likely to experience periodsof water supply shortages more severe than those...

Flow pathways are driven by hydraulic gradients but controlled by material permeability, which varies over many orders of magnitude and changes over time. Although millions of measurements of crustal properties have been made, including geophysical imaging and borehole tests, this vast amount of data and information has not been integrated into a comprehensive knowledge system. A community data infrastructure is needed to improve data access, enable large-scale synthetic analyses, and support representations of the subsurface in Earth system models. Here, we describe the motivation, vision, challenges,... Categories: Publication; Types: Citation
