| In this session we will discuss non-linear force-free coronal magnetic field models. The candidate models will be discussed, along with the associated issues of how to perform the preprocessing and validation of these models. We would like to determine which model to run, and how often, taking into account the uncertainties in the resulting magnetic field models. For example, would running one of the three candidate models once per hour for each active region be useful? Or would it be better to run all of the different models less frequently? Or would it be better to hold off running these models automatically, until their validity can be better established. To do these calculations, we need vector magnetic field data (as a boundary condition), H-alpha data (for the preprocessing), EUV images (for validation), as well as extrapolation codes and a loop-tracing algorithm (for the validation).

Coronal Magnetic Field Tools and Models II: Nonlinear Force-Free Models
Leader: Marc DeRosa
In this session we will discuss non-linear force-free coronal magnetic field models. The candidate models will be discussed, along with the associated issues of how to perform the preprocessing and validation of these models. We would like to determine which model to run, and how often, taking into account the uncertainties in the resulting magnetic field models.
Schedule
10:30 Session intro (DeRosa)
10:40 NLFFF preprocessing/methods overview (Wiegelmann)
11:00 Loop tracing methods overview (Aschwanden)
11:15 Community discussion (DeRosa)
Possible topics for the discussion session:
1. Given the current state of NLFFF modeling and validation, which model results are useful to the science community? Should the results be available, warts and all?
2. How often should the NLFFF models be run? Given the currently budgeted computational resources, we will likely have to trade off between the methods and the regions of interest.
3. Do we need additional resources to develop better H-alpha data (for the preprocessing), better loop tracing algorithms (for automated validation)?
