AB: The Hakamada-Akasofu-Fry (HAF) solar wind model has been used to simulate the ambient solar wind during quiet solar periods, and the propagation of interplanetary shocks and coronal mass ejections during times of solar activity. For the past five years the HAF model has played an important part in the real-time forecasting of solar wind conditions and the arrival of interplanetary shocks at Earth. Our group is now using the model to characterize and predict the propagation of disturbances beyond 1 AU. The model also maps the IMF lines connecting the traveling shock region to the Earth, to interplanetary spacecraft, and to other planets such as Mars. This allows simulation results to be compared with, and used to interpret, solar wind and energetic particle observations at Earth and at a variety of spacecraft locations. We will compare predicted solar wind characteristics with observations at Earth, Mars, and the Voyager spacecraft.
