- Description
- Shock-crossing data obtained from spacecraft are used to test the shock location models derived by Chapman and Cairns [2003] . Three sets of data are considered: (1) ISEE 1 for 24–25 September 1987, (2) Wind, Geotail, IMP 8, and Interball for the intervals 26–27 April and 10–13 May 1999, and (3) IMP 8, Geotail, Magion-4, and Cluster during the period 1973–2003 from the bow shock database (available at http://nssdc.gsfc.nasa.gov/ftphelper/bowshock.html). Derived from MHD simulations, the two shock models are for angles θ IMF = 45° and 90° between the upstream magnetic field B IMF and solar wind velocity v sw . These models have azimuthal asymmetries, and they depend explicitly on the upstream Mach number M A and ram pressure P ram. We also test Cairns et al.'s [1995] rotationally symmetric shock model. The new models perform better on average than the rotationally symmetric model, providing some evidence and support for the shock's shape being strongly dependent upon M A and θ IMF. We also compare our analyses here with model/spacecraft comparisons performed by Merka et al. [2003a] and discuss the importance of filtering on the model predictions.
