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.

OU and NSSL Research Scientists and Professor received NASA Group Achievement Awards

Research Scientist Dr. Pierre-Emmanuel Kirstetter (Advanced Radar Research Center & National Severe Storms Lab), along with Dr. Jonathan J. Gourley (National Severe Storms Lab) and Dr. Yang Hong (Civil Engineering & Environmental Sciences/Advanced Radar Research Center) are members on the Global Precipitation Measurement (GPM) Post-Launch Team recently selected for a NASA Agency Group Achievement Award with a citation “For exceeding all expectations for GPM operations, data processing, algorithm performance, science impact, and education and public outreach within one year after launch”. GPM is an international network of satellites that provides the next-generation observations of rain and snow across the entire globe. NASA’s most prestigious honor awards are approved by the Administrator and presented to a number of carefully selected individuals who have distinguished themselves by making outstanding contributions to the Agency’s mission. These NASA awards highlight the contribution of outstanding hydrometeorological research conducted on the Norman campus to advance our understanding of Earth’s water and energy cycle, improve forecasting of extreme events such as floods, and extend current capabilities in using accurate and timely observations of precipitation to directly benefit society.

Workshop on Higher Resolution SRTM Data and Flood Modeling

The U.S. government recently authorized the release of 1 arcsecond (approximately 30m) SRTM data for most of the globe. In support of the release of these data the Committee on Earth Observation Satellites (CEOS) and the Regional Centre for Space Science and Technology Education for Latin America and the Caribbean (CRECTEALC) hosted the Workshop on Higher Resolution SRTM Data & Flood Modeling to demonstrate the utility of the data in flood modeling applications. CRECTEALC and CEOS generously invited OU graduate students Zac Flamig and Race Clark to conduct an EF5 training course as a part of this effort.

The workshop (25-29 May 2015) was held at the cultural complex of the Meritorious Autonomous University of Puebla (BUAP) in Puebla, Puebla, Mexico and at the National Institute of Astrophysics, Optics, and Electronics (INAOE) in Tonantzintla, Puebla, Mexico. Included were participants representing Colombia, Honduras, Uruguay, Brazil, Venezuela, Costa Rica, Mexico, Guatemala, and the Dominican Republic. EF5’s participation in this workshop is part of an ongoing pattern of international outreach and capacity building activities on the part of the model development team. EF5 and CREST have now been presented on five continents to people from dozens of countries. Travel support for the training workshop was provided by the Secure World Foundation and the University of Oklahoma.

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.
