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: 2020.01.01 - 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
