Access
- Python (earthaccess):
use SunPy + VSO/JSOC; not via earthaccess - Portal: http://jsoc.stanford.edu/
- Pretrained weights: https://huggingface.co/nasa-ibm-ai4science/Surya-1.0
Gotchas
- Heliophysics has its own data system separate from EOSDIS
- Full-resolution data is petabytes; downsample temporally or spatially for most workflows
- Use SunPy, not raw FITS
