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.

Two FLASH Graduate Students Win Awards at 2015 AMS Annual Meeting

Zac Flamig and Race Clark received awards at the 95th Annual Meeting of the American Meteorological Society in Phoenix, AZ in January 2015. The awards were selected by the 31st Environmental Information Processing Technologies (EIPT) & the 5th Transition of Research to Operations (R2O) Conference Committees.


Mr. Flamig’s poster, entitled “HWT-Hydro: Evaluation of Experimental Forecast and Nowcast Tools” was selected as a 3rd Place Winner – Poster Presentation Category in the Joint EIPT-R2O Conferences Student Competition. Mr. Clark’s oral presentation, entitled “The Inaugural Hazardous Weather Testbed – Hydrology (HWT-Hydro) Experiment” was the 3rd Place Winner – Oral Presentation Category of the Joint EIPT-R2O Conferences Student Competition. Each will receive a $100 award and a Certificate of Appreciation. Both Mr. Flamig and Mr. Clark are currently PhD candidates at the University of Oklahoma’s School of Meteorology. Each works as a Graduate Research Assistant for the Cooperative Institute for Mesoscale Meteorological Studies at NOAA’s National Severe Storms Laboratory. Their PhD advisors are Dr. JJ Gourley (NOAA/NSSL) and Dr. Yang Hong (OU).

The FLASH project was heavily represented at the various conferences of the 95th Annual AMS Meeting. In addition to Mr. Flamig and Mr. Clark, Dr. JJ Gourley presented an evaluation of flash flood products from the FLASH project, Ms. Elizabeth Argyle presented on forecaster “best practices” during the HWT-Hydro Experiment, and Mr. Brandon Smith presented on observations collected in support of the HWT-Hydro Experiment. Funding for the research presented at the AMS meeting was provided by NOAA/OAR/Office of Weather and Air Quality (OWAQ) under the NOAA cooperative agreement, NA11OAR4320072.


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.
