Produced entirely from Quikscat data, this image illustrates the wealth of information available in scatterometer data. Over the ocean, colors indicate wind speed (blue is low, yellow high) while the wind direction is indicated with white streamlines. The land areas are enhanced resolution backscatter values ranging from high values in tropical vegetation to low values in the deserts. The sea ice extent at the poles is calculated from the scatterometer data and is imaged as enhanced resolution backscatter values. The dry snow zone and melt facies of Greenland can be clearly distinguished. Credit: BYU

VIRGINIA KEY, Fla. — One of the world’s renowned microwave remote sensing experts will present at this year’s University of Miami Rosenstiel School of Marine and Atmospheric Science’s Bader Lecture, to be held Wednesday, March 9 at 4 p.m. in the Rosenstiel School auditorium. Dr. David G. Long, professor of Electrical and Computer Engineering and director of Brigham Young University’s (BYU) Center for Remote Sensing (CERS), will discuss the use of radar scatterometry in studying the wind patterns on the oceans, variations in sea ice, and the health of vegetation in tropical climates at this free lecture geared toward academics and satellite remote sensing enthusiasts.

As an essential tool for the study of the Earth, microwave remote sensing can provide valuable information regarding the state of the oceans, polar regions, and vegetated areas. Long is engaged in interdisciplinary research and the development of a variety of advanced microwave remote sensing instruments, techniques, and applications, including the development of mesoscale models of oceanic winds for use in model-based wind retrieval.

Long earned his Bachelor’s and Master’s degrees in Electrical Engineering from Brigham Young University, and his Ph.D. from the University of Southern California. He is currently associate editor of the scholarly journal IEEE Geoscience and Remote Sensing Letters, as well as a member of the American Geophysical Union. As director of CERS, Long helps to coordinate research and academic activities across multiple colleges and departments.

The Bader Lecture is an annual event since 2000. G.J. and Naomi O. Wasserburg endowed the Henri and Adele Bader Lectureship at Rosenstiel School to honor famed glaciologist Henri Bader. Each year, a leading scientist is selected to spend three days in residence at Rosenstiel School and interact with students and younger faculty. During this time they give two lectures. One is a general lecture aimed at the entire faculty and student body of the Rosenstiel School. The other lecture is for a high school audience for the purpose of conveying the excitement and beauty of science. Long is scheduled to lecture at Ransom Everglades Middle School during his visit to South Florida. The divisions of Meteorology and Physical Oceanography, Applied Marine Physics, and Marine Geology and Geophysics take turns each year selecting the Bader lecturer – this year Applied Marine Physics invited the speaker.
