Sam Emmerson is an M.S. student in the School of Meteorology, studying with advisors Dr. Bob Palmer and Dr. David Bodine.
• My current work focuses on passive bistatic weather radars, particularly dual-Doppler retrievals of 2D and 3D wind fields. These prototype radar systems could be of high interest to the weather radar community due to their intrinsic low cost and ease of operation.
What do you like to do in your free time:
• When I’m not at home gaming or tinkering with stuff around the house, I can be found hiking, golfing, or rock climbing. However, if it’s springtime, I’m usually storm chasing!
Plans for after graduating:
• After completing my M.S., I will be pursuing a Ph.D here at the ARRC, where I will continue to broaden my work on bistatic weather radars, particularly focusing on bistatic polarimetry.

Congratulations to SoM/ARRC Ph.D. candidate Noah Brauer on being awarded an FY2021 NASA Future Investigators in NASA Earth and Space Science and Technology (FINESST) research grant!
The successor of the NASA Earth and Space Science Fellowship, the FINESST program provides research grants to graduate students who are designing and performing research projects relevant to interests of the NASA Science Mission Directorate. The Earth Science Research Program contributes to NASA's mission through the following key questions:
• How is the global Earth system changing?
• What causes these changes in the Earth system?
• How will the Earth system change in the future?
• How can Earth system science provide societal benefit?
Noah's proposed research focuses on improving the understanding of microphysics and rainfall processes in tropical cyclones. The analysis will leverage observations from the satellite-based Global Precipitation Measurement (GPM) mission along with ground-based radar and disdrometer data. This project will improve the representation of precipitation of tropical cyclones from space, of global precipitation characteristics in extreme rainfall scenarios, and the understanding how to enhance hydrological modeling and prediction of tropical cyclone precipitation and microphysics. The work addresses aspects of the 2017-2027 Decadal Survey and it is applicable to the water cycle, climate variability, and weather/atmospheric dynamics foci by targeting improved understanding and representations of extreme rainfall events to fully understand the climate system. Mr. Brauer is advised by Dr. Pierre Kirstetter with Dr. Jeffrey Basara and will continue his Ph.D. studies at the University of Oklahoma.
