Mr. Bedka has spent much of his entire professional career analyzing clouds and their micro and macro-physical properties using remote sensing observations. He is currently a member of the NASA LaRC Cloud and Radiation Research Group, led by Dr. Patrick Minnis. He has focused on: 1) development, validation, and application of a automated satellite-based convective initiation nowcasting, mesoscale atmospheric motion vector retrieval, overshooting convective cloud top detection, and enhanced-V signature detection algorithms, 2) development of satellite-based climatologies of hazardous convective storms, 3) cloud microphysical property retrievals using visible light and passive infrared observations, 4) exploring Earth Science applications for the next-generation of long-endurance uninhabited aerial vehicles (UAVs), and 5) development of and training on the use of innovative visualization methods for geophysical datasets. He has authored or co-authored 30+ peer-reviewed publications on these and other topics. He was the lead developer for the GOES-R Overshooting Top and Enhanced-V Signature Detection algorithm (delivered in 2011) and continues to perform algorithm development for and analysis of severe storms in support of the GOES-R Advanced Baseline Imager program. His work has incorporated datasets including cloud resolving model output, passive satellite observations from the global constellation of geosynchronous and polar-orbiting passive satellite imagers, active lidar and radar observations from CloudSat and CALIPSO, NOAA National Weather Service WSR-88D Doppler radar data, and 4-dimensional total lightning detection data.
