Daily time series of surface water input from rainfall, rain on snow, and snowmelt for the Conterminous United States from 1990 to 2023, as well as annual series of input seasonality, precipitation seasonality, and average rainfall, rain on snow, and snowmelt rates

This data release contains daily gridded data reflecting surface water input from rainfall, rain on snow (mixed), and snowmelt for the conterminous United States for water years 1990 to 2023 (1990/10/01 to 2023/09/30). This release also contains annual estimates of gridded input seasonality (an index reflecting whether surface water input occurs within a concentrated period or is equally distributed throughout the year), precipitation seasonality, average snowmelt, rainfall and rain on snow rates, and finally, annual totals of each input type. Average snowmelt, rainfall and rain on snow rates were computed using days where values were greater than zero. Daily data were generated using precipitation input from the...

The Influence of the North Pacific Jet Stream on Future Fire in California

In California, increased wildfire activity has been linked to decreasing snowpack and earlier snowmelt. Not only has this translated into a longer fire season, but reduced snowpack has cascading effects that impact streamflow, water supplies, agricultural productivity, and ecosystems. California receives 80% of its precipitation during the winter, so mountain snowpack plays a critical role in replenishing the state’s water supply. One factor that affects the amount of winter precipitation (and therefore snowpack) in California is the North Pacific Jet (NPJ)—a current of strong, high altitude winds that occur over the northern Pacific Ocean. Winters when the NPJ is located further north than normal are drier than...

Watershed Disturbance and Restoration Impacts on Hydrologic Function Relative to Increased Snowmelt Water Yields, Stream Water Quality, and Species Conservation in the Jemez Mountains, New Mexico: Model Calibration and Validation on a Landscape Scale

The overall project goal is to understand and model the watershed impacts of forest restoration actions (thinning, prescribed fire) and climate change on the hydrologic function, particularly with respect to (1) changes in soil moisture and water yield during snowmelt, (2) inter-annual and directional changes in stream water quality, and (3) the resulting impacts on watershed management for wildlife species threatened by disturbance and climate change.Specifically, we will: use known relationships of forest structure on snow-water equivalent (SWE) values and processes of sublimation (ablation), infiltration and run-off in the Jemez Mountains of northern New Mexico to model forest-stand restoration prescriptions,...
