Mary Keller

Mary Keller has extensive background in active and passive microwave remote sensing of Earth, the ocean, and the atmosphere. She has analyzed delay-Doppler ice sounding data to retrieve ice thickness over the Greenland and Antarctic ice sheets and derived Stokes parameters and daughter products for hybrid-polarity radars for planetary exploration applications. Keller has extensive experience in modeling and analysis of active and passive microwave remote sensing data to retrieve geophysical parameters from the ocean and from sea ice. As principal scientist in a wind-wave facility, she measured radar backscatter from water waves and targets under a wide variety of laboratory conditions and in the field. She led field efforts to calibrate active microwave sensors, measure atmospheric water vapor, and conduct stereo optical measurements of water waves. In addition, she developed analysis software for mine and unexploded ordnance (UXO) time decay signatures, analyzed data acquired from buried mines and false alarms, and presented the results to the scientific community. Finally, she contributed to analysis of ground and flight calibration efforts for spaceborne optical sensors for planetary exploration.
