The Spiros G. Geotis Prize is an award for the best student presentation(s) at the AMS Conference on Radar Meteorology. The award recipients are selected by a committee established by the program committee. High school, undergraduate, and graduate student presenters are eligible for the award. Upon receiving the award, students receive a cash prize, an AMS reference book, and a certificate.
This award was established to honor the pioneering contributions of Spiros G. Geotis to radar meteorology and his role as a mentor. Spiros (who went by "Speed") worked at Massachusetts Institute of Technology (MIT) for 40 years. Speed led efforts critical to the development of weather radars throughout his career, and contributed immensely to studies of radar polarization, hail, lightning, and microphysics. He was dedicated to mentoring students at MIT, including several who became influential researchers in radar meteorology. More information about Spiros Geotis's contribution to radar meteorology can be found in a Bulletin of the American Meteorological Society article describing his career, this award, and personal accounts of those who worked closely with him.
