The launch of the The Geostationary Operational Environmental Satellite-16 (GOES-16) satellite provides an opportunity to not only better understand trends of Atlantic Hurricanes during development and intensification, but also throughout and following landfall. Data from the GOES-16 Geostationary Lightning Mapper (GLM) and Advanced Baseline Imager (ABI) are combined with Multi-Radar Multi-Sensor (MRMS) products to better understand modification of the tropical systems during and after landfall. Utilizing data from three landfalling tropical cyclones from the 2017 Atlantic Season (Harvey, Irma, and Nate), azimuthal shear, vertically integrated liquid and ice, cloud-top temperatures and heights, and lightning flash rates of the inner core and individual storm cells associated with the broader rainbands are compared and quantified over time. The goal is that this combination of data will provide the increased utility of lightning data from GOES-16 and MRMS products in support of local severe and hazardous warnings during tropical cyclone landfall by showing the advantages of using multiple observing platforms.
