Principal Investigator

Charon Birkett

Description: This project provides a range of surface water products related to lakes, reservoirs, and wetlands in a near real time framework. It also offers a longer-term set of observations via integration of historical data sets. Products include water level, water extent, hypsometry and bathymetry...

Principal Investigator

Eric Hunt

Project Description: We are using the methodology outlined in Christian et al. (2019) to develop a global flash drought climatology using evaporative stress anomalies from the NASA MERRA-2 and ERA-Interim reanalysis datasets.  We are also examining specific case studies of flash drought that would...

Principal Investigator

Jack Eggleston

Project description: This primary goal of this project is to develop the workflow for operational space-based streamflow (discharge) measurement. The Alaska DOT and National Weather Service Alaska-Pacific River Forecast Center are long-term partners of the USGS and are representative of the hundreds of government...

Principal Investigator

Yu Zhang

Project description: Summary: Improve reservoir inflow forecasts by Texas river authorities and the Army Corps of Engineers by integrating NASA satellite precipitation estimates and soil moisture products. The goal is to improve precipitation estimates in areas NEXRAD coverage is poor and develop more reliable, real-time...

Principal Investigator

Rosemary Knight

Project Description: The goal of this work is to improve the quality and usefulness of groundwater models by incorporating information derived from interferometric synthetic aperture radar (InSAR) data and airborne electromagnetic (AEM) data. These improved groundwater models can then be adopted by water agencies to...

Principal Investigator

McKenzie Skiles

Description: It is critical to accurately model the timing and magnitude of snowmelt in the Colorado River Basin, where melt of the seasonal mountain snowpack dominates regional hydrology, populations are increasing, and snow melt patterns are shifting. This project addresses the limitations of temperature...

Principal Investigator

Nazmus Sazib

Project description: The project aims at improving the accuracy and resolution of the U.S. Department of Agriculture-Foreign Agricultural Service (USDA-FAS) root-zone soil moisture (RZSM) information by utilizing alternative NASA resources, including hydrologic models, forcing data, and satellite-based soil moisture data sets. The main objective...

Principal Investigator

Enrique Vivoni

Project Description: An ongoing drought in the Colorado River Basin has reduced levels in Lake Mead to the extent of triggering a reduction in Arizona’s Colorado River supply allocation under the Drought Contingency Plan agreement. Arizona State University and the Central Arizona Project have partnered...

Principal Investigator

John Reager

Project description: The aim of this project is to develop a groundwater numerical model using groundwater depletion from GRACE, land subsidence from InSAR, and in situ hydrologic data from U.S. Geological Survey (USGS) and California Department Water Resources (CA-DWR). The model, calibrated to GRACE groundwater...

Principal Investigator

Neil Carter

Our collaborator and end-user, the US National Park Service (NPS), has policy and legislative mandates to conserve acoustic and night sky environments unimpaired for the enjoyment of future generations. The rapid and unprecedented spread of anthropogenic nightlight and noise (ANLN) across the contiguous US jeopardizes...
