pyAMPP is a Python implementation of the Automatic Model Production Pipeline (AMPP) for solar coronal modeling. It streamlines the process of generating realistic 3D solar atmosphere models with minimal user input.
Full documentation is available at: https://pyampp.readthedocs.io/en/latest/
AMPP automates the production of 3D solar models by:
- Downloading vector magnetic field data from the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO)
- Optionally downloading contextual Atmospheric Imaging Assembly (AIA) data
- Performing magnetic field extrapolations (Potential and/or Nonlinear Force-Free Field)
- Generating synthetic plasma emission models assuming either steady-state or impulsive heating
- Producing non-LTE chromospheric models constrained by photospheric measurements
- Enabling interactive 3D inspection and customization through user-friendly GUIs
Install the latest version from PyPI:
pip install -U pyampppyAMPP installs two GUI applications:
- gxampp – Launches a GUI to select observation time and coordinates. It then invokes gxbox to build the 3D model.
- gxbox – Launches a GUI that builds and displays the 3D magnetic field and plasma model. Can be run independently if coordinates are known.
1. Launch the time/coord selector (gxampp)
gxampp2. Launch the modeling GUI directly (Gxbox Map Viewer)

The resulting model can be visualized in a VTK-based viewer (Gxbox 3D Viewer) that supports interactive exploration of the magnetic field structure.
Additionally, users can trace and extract magnetic field lines within the 3D model and send them back to the gxbox GUI, where they can be overlaid on solar images for contextual visualization.
Notes:
- --coords takes two floats, separated by space (no brackets or commas).
- One of --hpc, --hgc, or --hgs must be specified to define the coordinate system.
- Remaining parameters are optional and have default values.
After installation, the following commands become available:
gxampp: Launch the time and location GUI.gxbox: Launch the modeling GUI directly with CLI options.
