Distinguished Lecture Program on “Satellite Scatterometry: Winds, Vegetation, and Ice by Dr David G. Long
The distinguished lecture program of GRSS was organized on 11th September at 4:45 pm using virtual platform. The distinguished lecture was delivered by Dr David G Long. He is faculty of the Electrical and Computer Engineering department (www.ee.byu.edu) at Brigham Young University (www.byu.edu). Before this, he was employed at NASA's Jet Propulsion Laboratory (JPL) in the Radar Science and Engineering Section. He was responsible for the design and development of the NASA Scatterometer (NSCAT) system to measure ocean surface winds from space. NSCAT successfully flew aboard Japanese ADEOS spacecraft in 1996. He was a Group Leader in the Radar Systems Engineering Group at JPL were he supervised work on the design and analysis of spaceborne scatterometer and SAR systems including NSCAT, SIR-C, and Magellan. He was the original Experiment Manager for SCANSCAT (now known as SeaWinds, it was first launched in 1999 on QuikSCAT, again in 2003 on ADEOS-II, and again as RapidScat on the International Space Station in 2014). He has received several NASA Award of Achievement and Team Recognition Awards. His research interests include microwave remote sensing, spaceborne scatterometry, synthetic aperture radar, signal processing, polar ice, and mesoscale atmospheric dynamics. He is an associate editor for IEEE Geoscience and Remote Sensing Letters. He is a co-author of the textbook, F. Ulaby and D.G. Long, Microwave Radar and Radiometric Remote Sensing, ISBN: 978-0-472-11935-6, University of Michigan Press, Ann Arbor, Michigan, 2013, available through Artech House and Amazon.
The topic of lecture was Satellite Scatterometry: Winds, Vegetation, and Ice. With brief introduction about the faculty, Dr David Long presented his research work on Satellite scatterometry with applications related to winds, vegetation and ice. Satellite scatterometers have been built and flown by several nations including, the U.S., ESA, India, and China. Due to coarse resolution of scatterometer, it becomes difficult to evolve land based applications. Reprocessing of data for enhanced resolution foot print of few km helps us to use the instrument for land applications. These enhanced resolution products makes it as a powerful instrument for high resolution wind/rain estimation as well as in a variety of studies of polar ice and tropical vegetation. Dr David Long brought out many applications related to winds, vegetation and Antarctic iceberg monitoring. There were about 70 participants representing different countries.
