This report describes work that has been performed within the last year on the modeling of the disturbed magnetospheric magnetic field. The reasons for developing quantitative magnetospheric models are twofold: first, there are many model users who have practical needs. Their requirements are to specify and to predict such things as: radiation dose in the earth orbital environment, fluctuations in ionospheric electron density, variations in the earth's upper atmosphere density, and the impact of magnetic storms on loading changes in electrical power grids. The second set of model users have technical and scientific needs. They use the magnetic field models in studies of other magnetospheric, ionospheric, and upper atmospheric phenomena, or to understand the interactions of magnetospheric magnetic and electric fields with particle populations. This report should be the last of a series quantitatively describing the magnetospheric magnetic field. Some of the history of the magnetic field work that leads to the efforts pursued this last year is described. (Author) |
