# Dataset for Article: Rotation-Controlled Magnetotail Dynamics at Uranus: Asymmetric Current Sheet Morphology and Nightside IMF Coupling
Manuscript ID (AAS): AAS76813R1
Authors: Cao, X. et al.
Archive Host: Zenodo

## 1. Dataset Summary
This dataset contains numerical simulation outputs of "Rotation-Controlled Magnetotail Dynamics at Uranus: Asymmetric Current Sheet Morphology and Nightside IMF Coupling", including those for cross-sectional plots at multiple downtail distances, temporal-series evolution of the magnetotail, showing periodic variations during planetary rotation. All data correspond to the Figures 1-3 in the peer-reviewed article for ApJ (2026).

## 2. File Format Specification
| File Suffix | Format Introduction |
| ---- | ---- |
| .mat | standard structured binary data format where the simulation data are stored |
| .md  | Plain-text README.md file |

## 3. Relationship Between Dataset & Manuscript
- Files named Magnetotail_MHD_X*Ru_T*.mat: Raw data used to plot Figure 1-3 (near-tail & mid-tail& distant-tail cross-section); e.g., Magnetotail_MHD_X32Ru_T1 means the cross section at X = 32 Ru downtail region at time = T1.
