作为该项目的一部分,将根据2000年至2004年CHAMP和GRACE卫星上的恒星加速度计实验的加速度计测量得出400-450公里处的密度和跨轨道(准纬向)风速。在逐个风暴的基础上,将检查、解释风暴响应的强度、赤道穿透程度、时间延迟和密度扰动的其他特征,并将其与经验模式的预测进行比较。还将推导和解释风型。完整的数据集将存放在雪松数据库中。将对北美防空司令部目前使用的J70模型进行修正,以便更好地再现观测到的密度扰动。
英文摘要
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.
