Small uncrewed aircraft systems (sUxS) are now being routinely used not only for sampling atmospheric boundary layer (ABL) processes and land-atmosphere interactions but also have significant potential to improve weather forecasting at National Weather Service (NWS) Weather Forecast Offices (WFOs). In the present study, we used observations obtained from a Meteomatics Meteodrone SSE sUxS flown on 31 days between 20 August and 10 December 2020 near Oliver Springs, Tennessee, located 35 km northwest of Knoxville, Tennessee. We flew the sUxS up to 700 m above ground level, starting around sunrise and continuing every half hour until 3.5–4.0 hours past sunrise under synoptically quiescent, fair weather conditions. These datasets were provided in real time to the local NWS WFO in Morristown, Tennessee and used by forecasters there to assist with short-term operational forecasting needs. The sUxS profiles also provided finescale details on the early-morning transition over complex terrain and how this evolution varied during the late summer to winter period, which can be used to support the initialization of numerical weather prediction models.

This report describes the operation of NOAA/ARL/ATDD’s DJI S-1000 small Unmanned Aircraft System (sUAS) in the Verifications of the Origins of Rotation in Tornadoes Experiment Southeast (VORTEX-SE) in the spring of 2016. The S-1000 was used to measure temperature and humidity profiles in the lower 125-213 m of the atmosphere, and map the Earth’s skin temperature during three intensive observation periods (13 March, 24 March, and 27 April) in the VORTEX-SE experiment. Additionally, the S-1000 was used to perform a damage survey from an EF-2 tornado that occurred within the VORTEX-SE domain on 31 March 2016.
