Dataset title: Three-dimensional wind syntheses from airborne dual-Doppler datasets obtained during the VORTEX project used to investigate the structure of vortex lines in supercell thunderstorms in the Markowski et al. (2008) study Contact: Paul Markowski, Professor of Meteorology, Department of Meteorology & Atmospheric Science, pmarkowski@psu.edu, 814-865-0428 Last updated 2017 Summary The dataset contains airborne Doppler radar data and gridded 3D wind syntheses from the Verification of the Origins of Rotation in Tornadoes Experiment in 1994-1995, sponsored by the National Oceanic and Atmospheric Administration and National Science Foundation. The dataset also includes the code used for the interpolation of the raw radar data to a Cartesian grid and the dual-Doppler wind retrieval. The code used to construct the vortex lines also is included. Publications using these data: Markowski, P. M., J. M. Straka, E. N. Rasmussen, R. P. Davies-Jones, Y. Richardson, and R. J.
