Potential Field Source Surface PFSS Models

PFSS models are perhaps the most useful Sun-heliosphere connection models to date and have many applications (Arge et al., 2002 Luhmann et al., 2002 DeRosa and Schrijver, 2002). They use the potential field assumption mentioned above and hence decouple the coronal heating problem and the open-flux connection problem by making the inner corona exclusively magnetically dominated and time-independent. For a given choice of source surface radius, rs , the magnetic field potential then can be...
