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.

NOAA and NWS Officials Visit Norman, HWT-Hydro Experiment

On Wednesday, July 16, 2014, HWT-Hydro received a visit from NOAA Deputy Under Secretary Vice Adm. Michael S. Devany and National Weather Service Director Dr. Louis W. Uccellini. They were visiting Norman to see how research-to-operations (R2O) activities are conducted within the various NOAA units housed in the National Weather Center. Both officials discussed the ongoing efforts to align research activities at NSSL with the operational needs of the NWS. Dr. Uccellini described methods of easing the eventual R2O transition of the FLASH suite of forecast tools with the experiment’s principal investigator, Dr. JJ Gourley. Dr. Gourley also took the opportunity to explain how the various components of the FLASH product suite work in unison to give forecasters a view of heavy precipitation and flooding issues. Vice Adm. Devany and Dr. Uccellini visited during the middle of an experimental forecasting shift, where week 2 HWT-Hydro participants were monitoring potential flash flooding impacts in the High Plains and the Intermountain West. Week 2 participants are Britt Westergard (NWS Albany NY), Laura Belanger (NWS Peachtree City GA), Amanda Schroeder (NWS Fort Worth TX), and Jeff Waldstreicher (NWS Eastern Region).

Experimental activities have also attracted the attention of local media in central Oklahoma. Oklahoma City’s Fox affiliate, KOKH, aired a story about the experiment on Thursday, July 10. The KOKH story is available here: http://www.okcfox.com/story/25990371/forecasters-test-technology-to-better-predict-flash-floods.

Inaugural HWT-Hydro Experiment Wraps Up

After 4 weeks the inaugural HWT-Hydro Experiment has come to a close. During the month of July, we welcomed 17 total participants from NWS offices across the United States. Both the participants and the experiment coordinators took every opportunity to share ideas and knowledge in an effort to improve communication between the research and operational portions of the weather enterprise. Our weekly “Tales from the Testbed” webinars were well-attended, averaging between 20 and 30 remote NWS offices each week. Many of us have made plans to stay in touch and some of us will see each other again as soon as the NWS Flash Flood Summit in September, when the conversation about flash flood observations, forecasting, and modeling will broaden to include all of the National Weather Service’s partners across the US. We recommend watching this space for further news about this year’s experiment, including preliminary results. An overview of the experiment will be presented at the National Weather Association&amp’s annual meeting in Salt Lake City, UT in October. The FLASH research group has also submitted five HWT-Hydro-related abstracts to the 2015 AMS Annual Meeting which will be held in Phoenix, AZ in January.

Now let’s look back at the people who made the last four weeks possible. Thank you all!

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. For general information on the Graduate Programs, please visit the web site of Graduate College and respective Departments for application meterials.
