There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
Radar is an indispensable tool in the observation, analysis, and prediction of weather. The Weather Surveillance Radar 1988-Doppler (WSR-88D) is the primary source of weather-radar data in the United States (U.S.), providing dual-polarimetric (dual-pol) radar measurements for the inference of meteorological phenomena. The objective of this dissertation is to derive fundamental performance bounds for the variance of any unbiased estimator of the drop size distribution (DSD) parameters of rain, given the dual-pol measurements recorded by operational weather radars, e.g., the WSR-88D. This dissertation further establishes similar bounds for the estimation of rain rate and liquid water content (LWC).
