On 19 May 2010, during the Verification of the Origins of Rotation in Tornadoes Experiment 2 (VORTEX2), a Doppler on Wheels (DOW) radar recorded observations of a tornadic supercell near Kingfisher, OK. During this deployment, high-resolution single-Doppler radar data on a circulation within the rear-flank downdraft of a tornadic supercell were collected and are presented herein. These data will be edited for quality control and fields of reflectivity and radial velocity will be analyzed to determine the properties of the circulation, including its size and strength. Additionally, mobile mesonet data will be utilized to evaluate the thermodynamic characteristics of the ambient environment, the rear-flank downdraft, and of the circulation itself.
