Description
Magnetospheric substorms are global phenomena in which energy, transported from the solar wind into the magnetosphere where it is stored, is released and dissipated in the ionosphere and through other sinks. Since there are currently no continuous measures of flow of energy between the solar wind, magnetosphere, and ionosphere many empirical relations have been created to describe the transfer of energy between these different regions. From these, energy budgets have been created and studied to determine the relative roles of different energy sinks as well as determining the extent to which substorms are directly driven or a loading-unloading process. We will assess the dependence of the final energy budget on each of the inputs into these relations, and the variability in the estimate of total energy stored in the magnetosphere due to the choice of free parameters and empirical relations used to form the energy budget.
