Statistical Characterization and Modeling of Precipitation 

We are working on the statistical characterization of precipitation across multiple scales using gage records and weather radars, placing a particular focus on extremes. We are using this information to improve space-time stochastic precipitation models, as well as stationary and non-stationary spatial models of extreme precipitation. This work has been funded by the NSF Environmental Sustainability, NSF Smart & Connected Communities, and the NISF-NSF Disaster Resilience Research Grants programs.

Food-Energy-Water Nexus

Our research lab is part of an interdisciplinary team that is developing a basic scientific understanding of food, energy, and water (FEW) system dynamics to inform an integrated modeling, visualization, and decision support infrastructure for comprehensive systems. Our lab has developed a multi-resolution integrated modeling framework that explicitly captures the feedback among the FEW sectors at the metropolitan scale. This work has been funded by the NSF INFEWS program.

Averting Drought Shortages in the Colorado River, NASA’s Earth Science Division

Goal: provide long-range scenarios for water management for the Colorado River Basin. This project is in partnership with the Central Arizona Project. Our lab is improving the reliability of the Variable Infiltration Capacity large-scale hydrologic model in the Colorado River Basin using a suite of NASA remotely-sensed products.

Ensemble Generation of Downscaled Soil Moisture from Satellite Observations, NASA Terrestrial Hydrology program (completed).

Goal: design and calibrate a statistical downscaling model for generating high-resolution soil moisture fields from coarse satellite data using aircraft-based data collected during intensive field campaigns, as well as high-resolution (10 to 100 m) soil moisture fields generated by a distributed hydrologic model applied to a set of study basins.
