Dataset Card for 3D-NEXRAD

3D gridded radar reflectivity data collected from the U.S.NEXRAD WSR-88D radar network.

Dataset Description

The 3D-NEXRDA dataset comprises 3D radar observations of severe storm events across the United States, with each event captured at different geographic locations. The dataset provides high-resolution insights into storm dynamics with high temporal and spatial resolution.

• Temporal Coverage:

  • Time Span: 2022.01.01 - 2022.12.31

  • Interval and Event Duration: 25 frames for each sequence spanning a period of 125 minutes per event

  we are actively working to expand this dataset to cover the period from 2020 to 2022

• Spatial Dimensions:

  • Horizontal Resolution: 512 × 512 for Each observation frame

  • Vertical Resolution: 28 levels, from 0.5 km to 7 km with 0.5 km intervals, and from 7 km to 22 km with 1 km intervals

  • Available Variables: 7 radar variables:

    • Radar Reflectivity
    • Velocity Spectrum Width
    • Azimuthal Shear of the Radial Velocity
    • Radial Divergence of the Radial Velocity
    • Differential Radar Reflectivity
    • Specific Differential Phase
    • Copolar Correlation Coefficient

• Data Source:
