WINTRE-MIX: Enhanced Airborne Doppler Radar Data from the NRC Convair 580

Two airborne Doppler radars deployed on the National Research Council (NRC) Convair 580 aircraft collected data during nine research flights of the WINTRE-MIX field campaign. One of these radars operates at W-band (94.05 GHz) and is called NAW while the other operates at X-band (9.41 GHz) and is called NAX. The two radar systems in combination are called NAWX. This dataset is an enhanced subset of the companion datasets that were published by Nguyen and Wolde. Specifically, the data are separated into legs when the NRC Convair 580 was flying approximately straight and mostly at constant altitude. These are periods when Doppler velocities from the radars are most usable due to relatively stable aircraft attitude. The NAWX dataset described here is also an enhancement relative to the companion datasets in that improvements to beam pointing vectors have been implemented, allowing a more accurate navigation correction of Doppler velocities (i.e., removing aircraft motion from the Doppler velocity data). Additionally, new fields are included in the dataset such as horizontal wind corrected Doppler velocities and quality control masks to mitigate artifacts in the data (e.g., ground clutter).
