The Tempest Unmanned Aircraft System (UAS) was deployed by the University of Colorado/University of Nebraska UAS team during the 2010 VORTEX2 field campaign to make in-situ measurements of pressure, temperature, and humidity in the supercell environment using a miniature dropsonde integrated into a wing-mounted pod on the aircraft. In June 2013, the CU/UNL UAS team and a NSSL Mobile Mesonet team conducted a one-week deployment in northeast Colorado for the Airdata Verification and Integrated Tempest Experiment with the purpose to obtain collocated humidity and wind measurements that included data from a wing-integrated multi-hole probe. In August 2014, several small UAS were simultaneously flown at the 300-m meteorological tower at NOAA Boulder Atmospheric Observatory as part of the NSF-sponsored multi-UAS evaluation field experiment. This experiment was followed by
the first multi-UAS intercept of a thunderstorm gust front with each of the three UAS making
measurements at staggered altitudes with about 500-m horizontal separation. Results from these
deployments will be presented and the challenges for accurate in-situ wind measurements with UAS
will be discussed.
