Cross-wind from linear and angular satellite dynamics: The GOCE perspective on horizontal and vertical wind in the thermosphere

The decay of satellite orbits has been used extensively to obtain thermospheric density measurements. With the introduction of accelerometers in spacecraft, the spatial resolution of these data could be increased. At the same time, the direction of the measured acceleration provides a measure for the direction of the incoming flow, and therefore...
