This project will better determine the conditions under which near- Earth solar wind monitors can be relied upon to measure the parameters arriving at the dayside magnetopause. Using upstream spacecraft such as IMP-8, ISEE 1/2, and IRM, the project will attempt to (1) determine scale sizes of solar wind features, (2) compare observed and predicted time lags for tangential and rotationl discontinuities, (3) determine how well IMF Bz can be predicted from upstream monitors, (4) test if high time resolution magnetic field measurements can proxy for dynamic pressure, (5) determine how the foreshock preconditions the solar wind, and (6) determine how the waves generated by discontinuities interacting with the bow shock propagate to the magnetopause.

该项目将更好地确定在何种条件下可以依靠近地太阳风监测器来测量到达向阳面磁层顶的参数。 利用上游航天器，如IMP-8，ISEE 1/2，和E100，该项目将试图（1）确定太阳风特征的尺度大小，（2）比较切向和旋转不连续性的观测和预测时间滞后，（3）确定上游监测器预测IMF Bz的效果如何，（4）测试高时间分辨率的磁场测量是否可以代表动态压力，（5）确定前震如何预先确定太阳风，（6）确定不连续面与弓形激波相互作用产生的波如何传播到磁层顶。
