The commercial application of small Unmanned Aircraft Systems (UAS), which have much different weather sensitivities than manned aircraft, has shown exponential growth over the past 5 years leading to the need for new weather products tailored to meet their emerging needs. At the same time, plans for developing Unmanned Urban Mobility (UAM) has brought new challenges for the analysis and prediction of aviation weather in urban landscapes. Topics to be covered in this session include assessment of the weather sensitivities of these emerging modes of transportation (e.g., UAS, UAM), development and evaluation of finescale prediction systems to support unmanned operations, urban micrometeorology and impacts translation modeling which supports the integration of finescale weather information into UAS/UAM Traffic Management (UTM).
