# 🌞 SDO ML-Ready Dataset: AIA and HMI Level-1.5
## Overview
This dataset provides machine learning (ML)-ready solar data curated from NASA’s Solar Dynamics Observatory (SDO), covering observations from **May 13, 2010, to July 31, 2024**. It includes Level-1.5 processed data from:
- **Atmospheric Imaging Assembly (AIA)**:
- **Helioseismic and Magnetic Imager (HMI)**:
The dataset is designed to facilitate large-scale ML applications in heliophysics, such as solar activity forecasting, unsupervised representation learning, and scientific foundation model development.
