As part of this project, densities and cross-track (quasi-zonal) winds at 400-450 km will be derived from accelerometer measurements by the STAR accelerometer experiment on the CHAMP and GRACE satellites from 2000 through 2004. On a storm-by-storm basis, the magnitude of storm response, degree of equatorward penetration, time delays, and other characteristics of the density perturbations will be examined, interpreted and compared with predictions by empirical models. Wind patterns will also be derived and interpreted. The full data set will be deposited in the CEDAR database. Corrections will be made to the J70 model currently in use at NORAD, so as to better reproduce the observed density perturbations.

作为该项目的一部分，在2000年至2004年的Champ和Grace卫星上进行的加速度计测量，在400-450公里处的密度和跨轨道（准区域）将从加速度计的测量中得出。在风暴逐渐逐步的基础上。通过经验模型进行预测。 风模式也将得出和解释。 完整的数据集将存放在Cedar数据库中。 将对NORAD当前正在使用的J70模型进行校正，以便更好地再现观察到的密度扰动。
