Hydrologic Sciences and remote sensing


Hydrologic sciences and remote Sensing (HydSens) laboratory is an academic team in the Saint Anthony Falls Laboratory (SAFL) at the University of Minnesota.


The overarching goal is to better understand the physical laws of hydrologic water cycle and provide modern solutions for sustainability across water, food, and energy systems. 


May 2020, Ardeshir Ebtehaj received a 3-year funding from NASA to expand our understanding of the global life cycle of snow using satellite data. The project aims to better understand microwave signals of high-latitude snowfall to improve monitoring of changes of hydrologic water cycle in polar regions. NEW OPPORTUNITY! 

August 2019, Ardeshir is invited to present the results 

of the HydSens' research on high-resolution retrievals

of soil moisture and vegetation optical depth from space at NASA's Jet Propulsion Laboratory.

July 2019, Ardeshir received an Editor Award from the American Meteorological Society (AMS). The award presentation will take place in 100th AMS annual meeting.

June 2019, Lun Gao received a prestigious 

3-years fellowship from the Future Investigators

in NASA Earth and Space Science and

Technology (FINESST) program to advance

algorithms for improved retrievals of soil

moisture and vegetation water content from

The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as poetry.  - Bertrand Russell
