Surya-Bench Coronal Field Extrapolation Task
This foundation model task uses the foundation model to emulate the physics-based ADAPT-WSA PFSS code, driven by SDO/HMI observations. The parameters to predict are spherical harmonic coefficients which represent the magnetic potential for a domain between the photosphere and te source surface (set to 2.51 Rs). Included in these FITS files are other variables relating the WSA output that might be useful, such as photospheric polarity and open/closed masks.
See also the associated code on GitHub, which includes a pytorch data loader for use with the foundation model.
