Horizontal and vertical thermospheric cross-wind from GOCE linear and angular accelerations

摘要: Abstract Thermospheric wind measurements obtained from linear non-gravitational accelerations of the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite show discrepancies when compared to ground-based measurements. In this paper cross-wind is derived both angular using a newly developed iterative algorithm. The two resulting data sets are test validity quantify uncertainty in accelerometer-derived data. general difference found be less than 50 m/s vertically after high-pass filtering, 100 m/s horizontally. A sensitivity analysis reveals that continuous thrusting major source torque-derived wind, as magnetic properties satellite. energy accommodation coefficient identified particularly promising parameter for improving consistency thermospheric future. algorithm may applied obtain density other missions lack accelerometer data, provided attitude orbit known with sufficient accuracy.
