+# Dataset Card for 3D-NEXRAD
+
+<!-- Provide a quick summary of the dataset. -->
+
+3D gridded radar reflectivity data collected from the U.S.NEXRAD WSR-88D radar network. 
+
+## Dataset Description
+
+<!-- Provide a longer summary of what this dataset is. -->
+
+
+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:** 44 layers, spaced at 0.5 km intervals, covering altitudes from 0.5 km to 22 km.
+ 
+  - **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:**
+
+  This dataset was re-collected, collated and pre-processed from:
