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.

Our research discovered Global Vegetation Greening, combined with Climate Change, Promote Multi-decadal Rises of Global Land Evapotranspiration, accelerating global water cycles and potential regional drought risks.

Research highlights:
A team of researchers led by Ke Zhang, Yang Hong, and Jonathan Gourley recently discovered that Global Vegetation Greening, combined with Climate Change, Promote Multi-decadal Rises of Global Land Evapotranspiration, accelerating global water cycles and potential regional drought risks. The findings were published on Nature Publishing Group Scientific Report magazine’s website (

HighlightThe research team first generated a long-term global satellite record of land evapotranspiration using remote sensing satellite data since 1982. They investigated multi-decadal changes looking at trends between 1982 and 2013. In addition to global evapotranspiration trends, they examined vegetation greenness and general climate data including temperature, precipitation and cloudiness. Collectively, results show that during the past 32 years general increasing trends in both plant growth and evaporation with recent climate change mainly driven by vegetation greening and rising atmosphere moisture deficits. The study predicts that a continuation of these trends will likely exacerbate regional drought-induced disturbances, especially during regional dry climate phases associated with strong El Nino events.

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.
