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...

Description: This project seeks to provide high-resolution (i.e., daily, 30-m) soil moisture information to guide in-season irrigation decision support for vineyards equipped with variable-rate drip irrigation (VRDI) systems in the Central Valley of California. The primary water resource decision for these systems to when to...

Cities are complex systems with interconnected “lifeline networks” enabled by critical infrastructure, which can be severely damaged or destroyed in the aftermath of a natural disaster. Following Hurricanes Maria and Katrina and the Tōhoku earthquake and tsunami, for example, damage to critical systems resulted in...

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...

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...
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...

Over the past decade, increasing wildfire frequency and intensity in the United States has led to several devastating wildfire seasons. The United States’ fire-prone landscape is more densely settled and developed than in previous years, resulting in steeply rising fire-suppression costs. The Weather Research Forecasting...
Julie Padowski
Project Description: Fire disturbances in the Pacific Northwest (PNW) are projected to increase under a changing climate and are a major cause of increased erosion, runoff, suspended sediment, nutrient release, and debris flows in forested watersheds. Fire-related threats to water quality and quantity are of...

Hail is the costliest severe weather hazard for the insurance industry, damaging assets such as homes, businesses, agriculture, and infrastructure. Since most insurance companies do not reserve enough capital to cover catastrophes, they require reinsurance – insurance for insurance companies. The reinsurance industry uses...

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...
