Welcome to the Hydrometeorology and Remote Sensing (HyDROS) Laboratory

The HyDROS laboratory is a proud part of the University of Oklahoma (OU). We are located in the National Weather Center (NWC), Norman, Oklahoma. The HyDROS Lab is associated with the Advanced Radar Research Center (ARRC), Water Technology for Emerging Regions Center (WaTER), and the School of Civil Engineering & Environmental Science (CEES). The HyDROS Lab is a transdisciplinary research unit with synergy at the interface of remote sensing technology, water, weather, and climate. Scales of interest for modeling and prediction include the local, state, regional and global scales.

New Book: “Hydrologic Remote Sensing: Capacity Building for Sustainability and Resilience”


  • Presents an overview of the past, current and future remote sensing observations of the precipitation, soil moisture, evapotranspiration and total water storage
  • Reviews the various applications of remote sensing in hydrological/land surface/climate modeling and Ensemble Square Root Filter (EnSRF) data assimilation
  • Demonstrates techniques to help reduce devastating disasters triggered by hydrological hazards such as floods and landslides
  • Explains how remote sensing, modeling and data assimilation can be utilized to improve societal resilience and environmental sustainability
  • Shows how to create real-time flood and drought monitoring systems


Environmental remote sensing plays a critical role in observing key hydrological components such as precipitation, soil moisture, evapotranspiration and total water storage on a global scale. As water security is one of the most critical issues in the world, satellite remote sensing techniques are of particular importance for emerging regions which have inadequate in-situ gauge observations. This book reviews multiple remote sensing observations, the application of remote sensing in hydrological modeling, data assimilation and hydrological capacity building in emerging regions.


Students’ Awards in 2016 Student Research and Creativity Day held in University of Oklahoma,

HighlightCongratulations to Manabendra Saharia, CEES/ARRC PhD student, for winning the second prize in the oral presentation category of the 2016 Student Research and Creativity Day held in University of Oklahoma, Norman, March 4, 2016.
HighlightCongratulations to graduate student and PhD candidate Race Clark (OU/CIMMS) for winning the McNair’s Choice award for his poster in the Science A category of the 2016 Student Research and Creativity Day held in University of Oklahoma, Norman, March 4, 2016.

HyDROS' Grand Challenge is to observe and predict the storage, movement, and quality of water across space-time scales by integrating advanced sensing technology and numerical predictive models into an end-to-end research and application framework.

HyDROS' Mission is to propose technological solutions for mitigating the impacts of climate change and natural hazards through interdisciplinary research and education by using the latest remote sensing technology, information technology, and hydrological models in collaboration with private and public organizations at both local and international levels for the creation of a resilient society.

We will pursue our Grand Challenge and Mission through transdisciplinary research and education involving faculty, students, and scientists with Engineering, Sciences, Math, and Socioeconomic Sciences backgrounds as well as cooperation with universities, governmental agencies, private companies/industry, and international counterparts.

We are always looking for talented and enthusiastic students and researchers. We have advised students major in Civil Engineering, Hydrology (Water Resource Engineering), Environmental Science (Water Track), Geography, Meteorology, Computer Science and Geoinformatics.
