The team seeks to:
- More accurately and precisely measure flows throughout the solar convection zone: differential rotation, meridional circulation, and other large-scale flows, as well as their spatial and temporal variations.
- Investigate the interior physical conditions that are associated with emergences of large active regions and active nests.
- Better map dynamics and structures at the tachocline.
The Team has extensive expertise working with SOHO/MDI, GONG, and SDO/HMI observations and has extensive technical skills in global, ring-diagram, and time-distance helioseismic analysis methods. In addition to achieving the COFFIES scientific goals, they also compare results from different techniques and solve discrepancies arising from different methods.
Initial activities include:
- Reconcile flow results from different helioseismic techniques.
- Improve inversions of differential rotation.
- Characterize the thermal structure at and near the tachocline.
- Understand and remove the center-to-limb effect that complicates meridional circulation measurements.
