This dataset contains the mobile, ground-based Shared Mobile Atmospheric Research and Teaching (SMART) radar 2 dataset during the landfall of Hurricane Harvey (25-26 August 2017). The nearby United States Weather Surveillance Radar - 1988 Doppler (WSR-88D) in Corpus Christi, TX, USA was used to perform dual-Doppler analyses with SMART radar 2 to retrieve three-dimensional winds during Harvey's landfall. Included in this dataset are preliminary quality-controlled and dealiased Doppler velocity radar data, final quality-controlled and dealiased Doppler winds for volumes contributing to dual-Doppler analysis, unmodified dual-polarization moments from both radars, and dual-Doppler wind retrievals. This dataset is being submitted as a part of a Royal Meteorological Society Geoscience Data Journal submission entitled "Mobile Ground-Based SMART Radar Observations and Wind Retrievals During the Landfall of Hurricane Harvey (2017)." The use of this dataset should reference the manuscript once is has completed peer-review. The dataset is documented in detail in the manuscript and should be referenced for dataset structure.
